Answers

Answer 1

Answer:

1. Ionic Compound

2.Lithium Oxide

3. Li2O

Explanation:

This is an Ionic Compound because (Lithium) the metal or cation is giving away electrons to the oxygen a nonmental or anion so both can have a full valence electron shell or have all the electrons on the outer most shell.

This is also Lithium Oxide because the metal goes first then the nonmetal and the ending of the non metal is ending with an ide.

The chemical formula is the periodic table symbols (usually the metal first) and then the charges are switched. E.g  Sample A has charge of 3 and sample B has a charge of 2. The formula would be A2B3. If the charge is 1 then you can leave it blank because it is understood. E.g is sample B had a charge of 1 then it would be AB3

Sucrose (C12H22011) is combusted in air according to the following reaction:
C12H22011(s) + O2(g) = CO2(g) + H2O(l )
How many moles of carbon dioxide would be produced by the complete combustion of 38.5 grams of sucrose in the presence of excess oxygen?

Answers

Okay, let's break this down step-by-step:

1) The molecular formula for sucrose is C12H22011. This means each mole of sucrose contains 12 moles of carbon and 22 moles of hydrogen.

2) You are combusting 38.5 grams of sucrose. To convert grams to moles, we divide by the molar mass:

Molar mass of C12H22011 = 342.3 g/mol

So 38.5 g / 342.3 g/mol = 0.113 moles of sucrose

3) According to the combustion reaction, each mole of sucrose produces 12 moles of CO2.

So 0.113 moles of sucrose will produce 0.113 * 12 = 1.356 moles of CO2.

4) Round to the nearest whole number:

1 mole of CO2

Therefore, the complete combustion of 38.5 grams of sucrose in excess oxygen would produce 1 mole of carbon dioxide.

Let me know if you have any other questions!

3) The following reaction is at equilibrium, when pressure is increased:
H₂(g) + CO2(g) + heat H₂O(g) + CO(g)
10
A. In order to restore equilibrium, the reaction shifts left, toward reactants
B. In order to restore equilibrium, the reaction shifts right, toward products
C. No change occurs

Answers

The effect of increasing pressure on the given equilibrium reaction:

H₂(g) + CO₂(g) + heat ⇌ H₂O(g) + CO(g)

is determined by the stoichiometry of the reaction and the number of moles of gas on each side of the equation.

On the left-hand side, there are two moles of gas (H₂ and CO₂), whereas on the right-hand side, there are only one mole of gas (CO). Therefore, increasing the pressure will shift the equilibrium towards the side with fewer moles of gas, in order to decrease the overall pressure.

In this case, the reaction will shift towards the right, towards the products, to decrease the pressure. Therefore, the correct answer is:

B. In order to restore equilibrium, the reaction shifts right, toward products.

Answers

The reaction order and rate law for this reaction is first, rate = k[A]. Option A is correct.

The reaction order and rate law for a reaction can be determined from the slope of a plot of ln[A] versus time.

Given that the plot of ln[A] versus time resulted in a straight line with a slope value of -2.97 x 10⁻² min⁻¹, we can determine the reaction order and rate law as follows;

If the slope is equal to 1, the reaction order is 1st order.

If the slope is equal to 2, the reaction order is 2nd order.

If the slope is equal to 3, the reaction order is 3rd order.

From the given slope of -2.97 x 10⁻² min⁻¹, we can conclude that the reaction order is 1st order, because the slope value is equal to -1 times the reaction order. So, the reaction order for this reaction is 1st order.

The rate law for a 1st order reaction will be given by;

rate = k[A]

where [A] is the concentration of the reactant, and k is the rate constant.

Therefore,  first, rate = k[A].

Calculate the molality of a solution prepared by dissolving 19.9 g of KCl in 750.0 mL of water.

Answers

Answer:

Explanation:

First, we need to calculate the moles of KCl:

Calculate the molar mass of KCl:

KCl = 39.10 g/mol (atomic weight of K) + 35.45 g/mol (atomic weight of Cl)

= 74.55 g/mol

Calculate the moles of KCl:

moles of KCl = mass of KCl / molar mass of KCl

= 19.9 g / 74.55 g/mol

= 0.267 mol

Next, we need to convert the mass of the solvent (water) from milliliters to kilograms:

Convert mL to L:

750.0 mL = 750.0 mL * (1 L / 1000 mL)

= 0.7500 L

Calculate the mass of water:

mass of water = volume of water x density of water

= 0.7500 L x 1000 g/L

= 750.0 g

Convert the mass of water to kilograms:

mass of water = 750.0 g / 1000 g/kg

= 0.7500 kg

Now we can calculate the molality of the solution:

molality = moles of solute / mass of solvent (in kg)

molality = 0.267 mol / 0.7500 kg

= 0.356 mol/kg

Therefore, the molality of the solution is 0.356 mol/kg.

1. A new 125 g alloy of brass at 100°C is dropped into 76 g of water at 25 "C The final temperature of the water and brass is 35 "C. what is the specific heat of the sample of brass? The specific heat of water - 4.184 J/g. ​

Answers

We can solve this problem using the principle of conservation of energy, which states that the total energy of an isolated system remains constant.

The heat lost by the brass is equal to the heat gained by the water:

heat lost by brass = heat gained by water

The heat lost by the brass can be calculated as:

Qbrass = mbrass × cbrass × ΔT

where mbrass is the mass of the brass, cbrass is its specific heat, and ΔT is the change in temperature of the brass.

The heat gained by the water can be calculated as:

Qwater = mwater × cwater × ΔT

where mwater is the mass of the water, cwater is its specific heat, and ΔT is the change in temperature of the water.

Since the brass and water reach a final temperature of 35°C, we know that:

ΔT = Tfinal - Tinitial = 35°C - 25°C = 10°C

Plugging in the given values, we get:

Qbrass = mbrass × cbrass × ΔT = (0.125 kg) × cbrass × (10°C) = 1.25 cbrass J

Qwater = mwater × cwater × ΔT = (0.076 kg) × (4.184 J/g°C) × (10°C) = 31.97 J

Since Qbrass = Qwater, we can set the two equations equal to each other and solve for cbrass:

1.25 cbrass J = 31.97 J

cbrass = 31.97 J / 1.25 J/kg°C = 25.58 J/kg°C

Therefore, the specific heat of the brass sample is 25.58 J/kg°C.

what was its temperature at 346.9 mL?
T =

Answers

Answer:

216.9 K

Explanation:

We can use the combined gas law to solve this problem:

(P1V1/T1) = (P2V2/T2)

where P is pressure, V is volume, and T is temperature. We can assume that the pressure is constant, since the problem doesn't mention any changes in pressure.

Let's label the initial temperature T1 and the final temperature T2, and plug in the given values:

(P1V1/T1) = (P2V2/T2)

V1 = 346.9 mL

V2 = 596.2 mL

T2 = 373 K

(P1 * 346.9 mL / T1) = (P1 * 596.2 mL / 373 K)

Simplifying and solving for T1:

T1 = (P1 * 346.9 mL * 373 K) / (P1 * 596.2 mL)

T1 = (346.9 * 373) / 596.2

T1 = 216.9 K

Therefore, the temperature of the carbon dioxide sample at 346.9 mL was 216.9 K.

when 56.6 g of calcium and 30.5g of nitrogen gas under go a reaction that has 90% yield, what mass of calcium nitride is formed?​

Answers

Answer:

152.57 g

Explanation:

The balanced chemical equation for the reaction between calcium and nitrogen gas to form calcium nitride is:

3Ca + N2 → Ca3N2

From the balanced equation, we can see that the mole ratio between calcium and calcium nitride is 3:1. This means that 3 moles of calcium react to form 1 mole of calcium nitride.

First, let's calculate the number of moles of calcium and nitrogen gas given:

Mass of calcium = 56.6 g

Molar mass of calcium (Ca) = 40.08 g/mol

Moles of calcium = Mass of calcium / Molar mass of calcium = 56.6 g / 40.08 g/mol = 1.41 mol

Mass of nitrogen gas = 30.5 g

Molar mass of nitrogen gas (N2) = 28.02 g/mol

Moles of nitrogen gas = Mass of nitrogen gas / Molar mass of nitrogen gas = 30.5 g / 28.02 g/mol = 1.09 mol

Since the reaction has a 90% yield, only 90% of the limiting reactant (which is calcium in this case) will be converted to product. Therefore, we need to multiply the moles of calcium by 0.90 to account for the yield:

Moles of calcium nitride formed = Moles of calcium x Yield = 1.41 mol x 0.90 = 1.27 mol

Now, using the mole ratio from the balanced equation, we can determine the mass of calcium nitride formed:

Molar mass of calcium nitride (Ca3N2) = 40.08 g/mol (molar mass of calcium) x 3 + 14.01 g/mol (molar mass of nitrogen) x 2 = 120.25 g/mol

Mass of calcium nitride formed = Moles of calcium nitride formed x Molar mass of calcium nitride = 1.27 mol x 120.25 g/mol = 152.57 g

So, the mass of calcium nitride formed in the reaction is 152.57 g.

The amount of matter in an item is measured by the fundamental physical quantity known as mass. It is a scalar quantity that is measured in grams (g) or kilograms (kg) (g). No matter where it is or what force is pushing against it, an object's mass always remains constant.

How do you determine it?

For butane and oxygen to burn, the chemical equation is balanced as follows:

2C4H10+13 O2→ 8 CO2+ 10 H2O

According to the equation, 1 mole of butane (C4H10) and 13/2 moles of oxygen (O2) combine to form 5 moles of water (H2O).

To begin with, we must count the butane moles that are present:

Mass of butane divided by its molar mass yields moles of butane.

1.03 g/58.12 g/mol is the formula for butane.

A mole of butane weighs 0.0177 mol.

Then, we can calculate the quantity of water created using the butane-to-water mole ratio:

Moles of water = [tex]\frac{5 mol H2O}{(1 mol C4H10 ×0.0177 mol C4H10)}[/tex] = 0.0885 mol.

Eventually, we can determine how much water was generated:

moles of water equal 0.0885 mol when 5 mol H2O is divided by 1 mol C4H10 and multiplied by 0.0177 mol C4H10.

Lastly, we can determine the mass of created water:

Water's mass is equal to its moles times its molar mass= 0.0885 mol × 18.02 g/mol = 1.59 g.

As a result, 1.03 g of butane will yield 1.59 g of water when it reacts with to moles of water equal 0.0885 mol when 5 mol H2O is divided by 1 mol C4H10 and multiplied by 0.0177 mol C4H10.

Lastly, we can determine the mass of created water:

Water's mass is equal to its moles times its molar mass = 0.0885 mol × 18.02 g/mol = 1.59 g.

As a result, 1.03 g of butane will yield 1.59 g of water when it reacts with too much oxygen.

Determine which statements are consistent with Daltons atomic theory

Answers

Answer:

Explanation:

Dalton's atomic theory had several postulates, including:

1. All matter is made up of atoms, which are indivisible and indestructible.

2. All atoms of a given element are identical in mass and properties.

3. Compounds are formed by a combination of two or more different kinds of atoms.

4. A chemical reaction is a rearrangement of atoms.

Based on these postulates, the following statements are consistent with Dalton's atomic theory:

1. Chemical reactions involve the rearrangement of atoms to form new compounds.

2. Elements are composed of small, indivisible particles called atoms.

3. Atoms of the same element have the same mass and chemical properties.

4. A compound is made up of two or more different elements.

5. Atoms can neither be created nor destroyed in a chemical reaction.

However, the following statements are not consistent with Dalton's atomic theory:

1. Atoms are divisible into smaller particles.

2. Isotopes of the same element have different chemical properties.

3. The mass of an atom is distributed uniformly throughout the atom.

It's worth noting that while Dalton's atomic theory has been largely superseded by modern atomic theory, it remains an important historical milestone in the development of atomic theory.

A compound has a similar molecular mass of 180grams/mol. It contains 40.8% carbon,5.8% hydrogen and 53.4% oxygen. Calculate its empirical formula and molecular formula, and give its common name.

Answers

Answer:

To find the empirical formula of the compound, we need to determine the simplest whole-number ratio of atoms in the molecule.

First, we can assume that we have 100 grams of the compound, and calculate the number of moles of each element present in it:

Carbon: 40.8 g / 12.011 g/mol = 3.398 mol

Hydrogen: 5.8 g / 1.008 g/mol = 5.753 mol

Oxygen: 53.4 g / 15.999 g/mol = 3.337 mol

Next, we divide each of these values by the smallest one, which is 3.337, to get the mole ratio:

Carbon: 3.398 mol / 3.337 mol = 1.019

Hydrogen: 5.753 mol / 3.337 mol = 1.723

Oxygen: 3.337 mol / 3.337 mol = 1.000

Rounding these values to the nearest whole number, we get the empirical formula: C1.0H1.7O1.0, which can be simplified to CH1.7O.

To find the molecular formula, we need to know the actual molecular mass of the compound. We can estimate it by adding the atomic masses of the elements in the empirical formula:

Carbon: 1 x 12.011 = 12.011

Hydrogen: 1.7 x 1.008 = 1.714

Oxygen: 1 x 15.999 = 15.999

Total = 29.724 g/mol (approx.)

The molecular mass is close to 180 g/mol, which suggests that the actual molecular formula is a multiple of the empirical formula. Dividing 180 by 29.724, we get a value of about 6.05. Multiplying the subscripts in the empirical formula by this value, we get the molecular formula: C6H10.2O6, which can be further simplified to C3H5.1O3.

The compound with the empirical formula CH1.7O and the molecular formula C3H5.1O3 is commonly known as glyoxylic acid.

Under what conditions would one mole of methane gas, ch4 , occupy the smallest volume?

Answers

Under the condition A. 273 K and 1.01 × [tex]10^{5}[/tex] Pa, one mole of methane gas, [tex]CH_{4}[/tex], occupy the smallest volume.

What is the smallest volume ?

The ideal gas law, PV = nRT, can be rearranged to solve for volume as V = nRT/P, where V is volume, n is the number of moles, R is the gas constant, T is temperature in Kelvin, and P is pressure.

To find the conditions under which one mole of methane gas occupies the smallest volume, we need to find the combination of temperature and pressure that results in the smallest volume.

Using the equation V = nRT/P, we can see that volume is inversely proportional to pressure, so we want the highest pressure possible. Therefore, we can eliminate choices A and C, which have lower pressures than B and D.

Next, we need to consider temperature. Using the same equation, we can see that volume is directly proportional to temperature, so we want the lowest temperature possible. Therefore, the correct choice is A, which has a temperature of 273 K, the lowest temperature of all the choices.

Therefore, the answer is A. 273 K and 1.01  × [tex]10^{5}[/tex]  Pa.

A compound contains 0.58 m Ag, 0.58 mol N, and 1.79 mol O. What is its empirical formula?

Answers

Explanation:

To find the empirical formula of the compound, we need to determine the simplest whole-number ratio of the atoms in the compound.

First, we need to find the number of moles of Ag, N, and O relative to each other. The smallest number of moles is used as a reference point, and the other moles are divided by this value to get their ratios:

0.58 mol Ag : 0.58 mol N : 1.79 mol O

Dividing each mole value by 0.58 mol (the smallest number of moles), we get:

1 mol Ag : 1 mol N : 3.09 mol O

We can see that the ratio of Ag:N:O is 1:1:3.09. However, we need to express the ratio in whole numbers, so we divide each number by the smallest number in the set of ratios:

1 : 1 : 3.09/1.00 ≈ 3.

Rounding to the nearest whole number, we get the empirical formula of the compound:

AgN3O3

Therefore, the empirical formula of the compound is AgN3O3.
