10.2234 kJ of heat is needed to completely melt 1.70 moles of H2O, given that the water is at its melting point and the heat of fusion for water is 6.02 kJ/mole.

What is latent heat?

The term "latent heat" refers to the heat energy that a substance retains when its phase changes during a specific process. The latent heat of evaporation, which occurs when a liquid absorbs heat from an external source at its boiling point, is one of many types of latent heat.

Similarly, the latent heat of fusion is used when any substance melt at its melting point to change the liquid phase of that substance.

As given in the problem, The heat of fusion for water is 6.02 kJ/mole. This means 6.02 kJ heat is needed to melt 1 mole of ice into water

Then the heat are needed to completely melt 1.70 moles of H2O,

Heat  = 1.70 moles ×6.02 kJ/mole

Heat = 10.2234 kJ

Thus, the heat needed to completely melt 1.70 moles of H2O is 10.2234 kJ

A molecule has sp3 hybridization with 1 lone pair. The electron pair geometry of this molecule is:________ . The geometry of this molecule is:___________ This molecule will have approximate bond angles of (If more than one bond angle is possible, separate each with a space.):______

Answers

Answer:

Tetrahedral

Trigonal pyramidal

less than 109.5°

Explanation:

If a molecule has a hybridization of sp3 it must have four electron domains which corresponds to a tetrahedral geometry.

Now we were told that the molecule also has one lone pair. It means that one out of the four electron domains is composed of a lone pair. Thus the molecular geometry will be trigonal pyramidal (e.g NH3).

Recall that lone pairs usually decrease the bond angle to a value less than the expected value for that particular electron domain geometry.

The expected bond angle for a tetrahedral geometry is 109.5° but that of the trigonal planar geometry is less than this.

If 1.0 mol of N2 and 3.0 mol of H2 in a closed container initially at STP react completely in the reaction shown below, then the final pressure in the flask will be ________ atm at 273 K.

Answers

Answer:

[tex]p_f=0.5atm[/tex]

Explanation:

Hello!

In this case, since the reaction between nitrogen and hydrogen produces ammonia:

[tex]N_2+3H_2\rightarrow 2NH_3[/tex]

We can compute the volume of the container by using the ideal gas law at STP (1 atm and 273.15 K):

[tex]V=\frac{4.0mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}=89.7L[/tex]

Next, since nitrogen and hydrogen are in a 1:3 mole ratio, we understand all the nitrogen and hydrogen are consumed and only ammonia remains at the end of the reaction in the following amount:

[tex]n_{NH_3}=1.0molN_2*\frac{2molNH_3}{1molN_2} =2.0molNH_3[/tex]

Thus, the final pressure turns out:

[tex]p_f=\frac{2.0mol*0.08206\frac{atm*L}{mol*K}*273.15K}{89.7L}\\\\p_f=0.5atm[/tex]

According to Boyle’s law, when the pressure of a gas increases at constant temperature, its volume

Answers

Answer:

reduces

Explanation:

According to Boyle's law, when the pressure of a gas increases at constant temperature the volume reduces.

Boyle's law states that "the volume of fixed mass of a gas is inversely proportional to the change in pressure if the temperature is constant".

It suggests that at constant temperature, if pressure increases, temperature reduces.

Mathematically, it is expressed as;

     P1 V1  = P2 V2

P and V are pressures

1 and 2 are initial and finals state.

Boyle's law is stated for the ideal gas at a constant temperature. According to Boyle's law, with an increase in pressure, the volume of the gas decreases.

What is an ideal gas?

The ideal gas is given as the gas in which the interatomic collisions are zero, and the changes are produced with the collisions to the walls.

Boyle's law is stated as the gas is at a constant temperature. According to the ideal gas, the pressure and volume are inversely related.

With the increase in pressure, the volume of the gas decreases and vice versa.

For an aqueous solution of sucrose (C12H22O11), determine: (a) the molarity of 3.30 L of a solution that contains 225.0 g of sucrose M (b) the volume of this solution that would contain 4.30 mole of sucrose L (c) the number of moles of sucrose in 1.00 L of this solution mol C12H22O11

Answers

Answer:

a) Molarity = 0.199M

b) 21.6L of solution

c) 0.199 moles of sucrose in 1L

Explanation:

a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):

Moles sucrose -Molar mass: 342,3g/mol-:

225.0g * (1mol / 342,2965g) = 0.6573 moles

Molarity = 0.6573 moles / 3.30L

Molarity = 0.199M

b) 0.199M means 0.199 moles in 1L. 4.30 moles are in:

4.30 mol * (1L / 0.199mol) = 21.6L of solution

c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M

The molarity of 3.30 L of a solution that contains 225.0 g of sucrose is 0.2MThe volume of this solution that would contain 4.30 mole of sucrose is 21.5LThe number of moles of sucrose in 1.00L of this solution is 0.2mol

HOW TO CALCULATE MOLARITY:

The molarity of a solution can be calculated by dividing the number of moles of the substance by its volume. That is:

Molarity (M) = no. of moles ÷ volume

QUESTION A:

Molar mass of C12H22O11 = 342.3 g/molno. of moles = 225g ÷ 342.3g/mol = 0.66mol

Molarity of sucrose = 0.66mol ÷ 3.30L = 0.2M

QUESTION B:

Volume = no. of moles ÷ molarity

Volume = 4.30 mol ÷ 0.2M = 21.5L

QUESTION C:

no. of moles = molarity × volume

no. of moles = 0.2M × 1L

no. of moles = 0.2mol

this * 16 =15.43 grams

According to stoichiometry and balanced chemical equation of iron and oxygen 17.15 g of rust is produced when 12 g iron reacts with oxygen.

What is  stoichiometry?

Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.

The balanced chemical equation for formation of rust when iron reacts with oxygen  is,

4 Fe + 3 O₂[tex]\rightarrow[/tex] 2 Fe₂O₃

223.36 g of iron produces 319.38 g of rust

∴ 12 g iron will produce 12×319.38/223.36= 17.15 g of rust.

Therefore, 17.15 g rust is produced from 12 g iron when it reacts with oxygen.

Andy rides a a speed of 8 miles per hour. How far does he ride in 3 hours?

Answers

Answer:

The answer is 24 miles.

Explanation:

Every hour he rides 8 hours. If he rides for three hours you can take 8 miles x 3 hours which is 24 miles.

The speed of the  riding is 8 miles/hours . Within a time of 3 hours Andy will go for a distance of 24 miles.

What is speed?

Speed is a physical quantity which measures the distance covered per unit time. The rate of speed is called velocity both having the units m/s, km/hr, miles/hr etc.

Speed is directly related to the distance covered. As the speed increases, distance covered by the object also increases. Whereas as the time increases, distance covered will decreases.

Given the speed of ride = 8 miles/s

time  = 3 hours.

Distance = speed × time.

               = 8 miles/ hr × 3 hours

               = 24 miles.

Therefore, Andy will reach out a distance of 24 miles within 3 hours when ride with a speed of 8 miles/s.
