Answer:D
Explanation:
The equilibrium partial pressure of D is 0.362atm.
2A(g) + B(s) <==> 2C(s) + D(g)
The pressure that a gas, in a mixture of gases, would exert if it alone occupied the whole volume occupied by the mixture is called partial pressure of the gas.
In the equilibrium expression, we ignore solids as they are considered to have a value of unity. Thus, we can write the equilibrium expression for the above reaction as:
K = (PD) / (PA)²
where, K = Partial pressure equilibrium
PD = Partial pressure of gas D
PA = Partial pressure of gas A
Kp = 8210
PA = 0.021 atm
8210 = PD / (0.021)²
PD = 8210 × (0.021)²
PD = 0.362 atm.

Please explain/show how to create a concept map with the following terms. See picture for question. Thank you
Answer:
We are asked to create a concept map with the terms:
• chemical bonds
,• ionic bonds
,• covalent bonds
,• metallic bonds
,• Molecules
,• ions
As we can see we have a general topic which is chemical bonds.
Then we have 3 different types of bonds: ionic, covalent and metallic.
Finally, these types of bonds can form either molecules or an array of ions (in the case of metallic bonds.
In orther to understant it better we first list the deffinitions of these 3 types of bonding:
Covalent bonds: is a bond between two atoms that share a pair of valence electrons. This bond produces a molecule.
Ionic bonds: is a bond between a metallic element and a non metallic element. The first gives electrones to the other, resulting in a molecule.
Metallic bonds: these are bonds that result exclusevely in metal compound. Metals are crystalline solids, a huge array of atoms that share valence electrones.
Therefore we can array these concepts in the following map:
A beaker is filled with 225.0mL of sodium hydroxide solution with an unknown concentration. A 0.00100 M solution of HCI is used in the titration. the equivalence point is reached when 27.0mL of HCI have been added.What is the initial concentration of NaOH in the beaker
The titration formula is used when we have an equivalence point of neutralization between acid and base, the formula is:
Ma * Va = Vb * Mb
Where:
Ma = concentration of acid
Va = volume of acid
Mb = concentration of base
Vb = volume of base
This formula tells us the concentration and volume of an acid must be equal to the concentration and volume of a base in order to neutralize the reaction (this applies to strong acids and strong bases only)
Ma * Va = Vb * Mb
0.00100 * 27 = 225 * Mb
0.027 = 225Mb
Mb = 0.00012M

The heat released by the experiment, assuming that the solution's final volume is 200.0 mL, the density is 1.00 g/mL, and the heat capacity is 4.184 J/g⋅°C is -194 KJ/mol.
What is density?Density is defined as mass of a material substance per unit of the volume. The equation for density is d = M/V, where d stands for density, M for mass, and V for volume.
Grams per cubic centimeter are a common unit of density measurement. For instance, the density of Earth is 5.51 grams per cubic centimeter, whereas the density of water is 1 gram per cubic centimeter.
The equation of the reaction is;
CaOH(aq) + 2HCl(aq) --------> CaCl2(aq) + 2H2O(l)
From the information provided in the question;
No. of moles of CaO = 1.23 g/ 56 g/mol = 0.022 moles
No. of moles of HCl = 0.500 M × 200/1000 = 0.1 moles
We now have to obtain the limiting reactant
From the reaction equation;
one mole of CaO reacts with 2 moles of HCl
0.022 moles moles of CaO reacts with 0.022 moles × 2 moles/1 mole
= 0.044 moles
Hence there is more than enough HCl so CaO is the limiting reactant.
Temperature rise of the reaction = 5.10 °C
Total volume of solution = 200.0 ml
Density of solution = 1.00 g/ml
Mass of solution = 200 g
Heat capacity of solution = 4.184 J/g·°C
We know that, heat absorbed by solution = heat released by the reaction
Heat absorbed by solution = mcθ
m = mass of solution
c = heat capacity of solution
θ = temperature rise
Substituting values;
ΔH = 200g × 4.184J/g·°C × 5.10°C
ΔH = 4.27 KJ
Therefore, heat released by the reaction;
ΔHrxn = (- 4.27 KJ)/0.022 moles
ΔHrxn = -194 KJ/mol

would He gain stability by adding one H
Helium gains no stability by adding one H because it is already stable due to a complete valance shell or orbit.
How do elements gain stability?
To attain stability an atom will gain, lose, or share electrons to complete the outermost shell means the last shell. Helium atom has two electrons in the first orbit which completes the doublet rule so it is stable we know that noble gases are stable elements and we know that helium is also a member of a noble family. Nuclides are the most stable because it contains even numbers of both protons and neutrons which make them less radioactive. Nuclear stability is greater in nuclides that comprise even numbers of protons and neutrons or both.

a balloon has a volume of 1.20 L at 24.0 C. The balloon is heated to 48.0 C. Calculate the new volume of the balloon.
Answer
To solve this excescise we use the ideal gas equation:
[tex]P.V=n.R.T[/tex]Where:
P is the pressure of the gas
V is the volume
T is the temperature
R is the ideal gas constant
n is the number of moles
As the balloon is a closed recipient n is the same in state 1 (T: 24°C) and state 2 (T: 48°C).
R is a constant so also remains the same.
The pressure is also a constant in this case as the only thing that we do to the balloon is heat it.
So therefore:
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}=\frac{n.R}{P}[/tex]Now we calculate the volume at 48°C (V2):
[tex]V_2=\frac{V_{1.}T_2}{T_1}=\frac{1.2L.48\degree C{}}{24\degree C}=2.4L[/tex]As we can see as the temperature rises the volume of the gas increases because the molecules have more kinetic energt and they remain farther apart.
The answer then is the new volume of the balloon is 2.4L

What is the molarity of a solution containing 14.6 g of KCl in 281 mL of KCl solution?
Answer:
0.698 M.
Explanation:
Let's remember the concept of molarity: The molarity (M) of a solution is the number of moles of solute dissolved in one liter of solution. To calculate the molarity of a solution, divide the moles of solute by the volume of the solution expressed in liters, like this:
[tex]Molarity\text{ \lparen M\rparen=}\frac{moles\text{ of solute}}{liter\text{s of solution}}=\frac{mol}{L}.[/tex]To find the moles of solute (KCl, in this case) we have to convert 14.6 g of KCl to moles using its molar mass which is 74.5 g/mol, like this:
[tex]14.6\text{ g KCl}\cdot\frac{1\text{ mol KCl}}{74.5\text{ g KCl}}=0.196\text{ moles KCl.}[/tex]Now, let's convert 281 mL to L. Remember that 1 L equals 1000 mL:
[tex]281\text{ mL}\cdot\frac{1\text{ L}}{1000\text{ mL}}=0.281\text{ L.}[/tex]The final step is to replace the data that we obtained in the molarity formula:
[tex]Molarity=\frac{0.196\text{ moles}}{0.281\text{ L}}=0.698\text{ M.}[/tex]The answer would be that the molarity of the solution is 0.698 M.

How many moles of C₂H5OH
are there in 45.0 mL of 0.250 M
C₂H5OH?
Answer:
no. of moles = 0.0113
Explanation:
To calculate the number of moles of a substance given its concentration and volume, we can use the following formula:
[tex]\boxed{\mathrm{No. \ of \ moles = Concentration \times \frac{Volume}{1000}}}[/tex],
where concentration is mole/dm³ or M, and volume is in cm³ or ml.
In this question, we are told that:
• concentration = 0.250 M
• volume = 45.0 ml
Substituting these values into the formula above, we get:
No. of moles = [tex]0.250 \times \frac{45.0}{1000}[/tex]
= [tex]0.250 \times 0.045[/tex]
= 0.01125
[tex]\approx[/tex] 0.0113 (3 s.f.)
Therefore, the number of moles of C₂H₅OH is 0.0113.
The 0.0112 moles of C2H5OH are present in the 0.250 M solution of C2H5OH.
What is a mole?
Mole is used as a concentration unit in chemistry terms. One mole is equal to the mass of the given compound which is divided by the molar mass of the same compound.
Given:
M= 0.250M ( M stands for molarity)
Volume = 45.0 ml
The molar mass of C2H5OH = 46.07 g/mol
Now, we use molarity formula M = Moles of the substance/volume in liter
Let say moles = x
Units of M = mol/L
Therefore, units of volume need to be converted in to Liters = 1L = 1000ml
By using molarity equation, X= 45.0*0.250/1000 = 0.0112 moles
Hence, the required number of moles of C2H5OH = 0.0112 moles.

Because amount has no effect on mass percentages, the mass percentage of carbon in 5, 50, and 500 g of sucrose is 42.1 %
The mass:
It also represents the body's inertia, or resistance to acceleration (change in velocity) when a net force is applied. The mass of an object dictates the strength of its gravitational attraction to other bodies.
The kilogram is the SI base unit of mass (kg). Mass is not the same as weight in physics, despite the fact that mass is frequently calculated by measuring the object's weight using a spring scale rather than a balance scale and comparing it directly with known masses. Because of the reduced gravity, an object on the Moon would weigh less than it does on Earth, yet it would still have the same mass.
Molecular formula of sucrose is C12 H22 O11
Molar mass of Sucrose , C12 H22 O11 is = ( 12 x 12 ) + ( 22 x 1 ) + ( 11 x 16 ) g/mol
= 342 g/mol
The molar mass of Carbon is 12 g/mol
342 g of C12 H22 O11 contains 12 x 12 g of C
5 g of C12 H22 O11 contains Y g of C
Y = ( 12x12x 5 ) / 342
= 2.105 g of C
mass % of C = (mass of C / mass of sucrose ) x 100
= (2.105 / 5 ) x 100
= 42.1 %
342 g of C12 H22 O11 contains 12 x 12 g of C
50.0 g of C12 H22 O11 contains Y g of C
Y = ( 12x12x 50 ) / 342

The atomic size of elements increases down a group but decreases across a period.
The reason for this trend is that, on going down a group, an extra electron shell is added to the element below. However, across a period, the electron shell remains the same whereas the size of the positive nuclear charge increases, therefore, the atomic size of atoms in the same period decreases from left to right across the period.

(COOH)₂ (aq) + 2 NaOH (aq) ---> (COONa)₂ (aq) + H₂O (l)
The mole ratio of oxalic acid to NaOH is 1 : 2
moles = volume * molaritymoles of NaOH = Moles of oxalic acid /2
Moles of NaOH = 35.2 mL * 0.546 = 19.2 mmoles
Moles of oxalic acid = 19.2 / 2 = 9.6 mmoles
Volume of oxalic acid required = 9.6 / 0.125
Volume of oxalic acid = 76.8 mL
