B. AH = 31 kJ/mol, AS = 0.093 kJ/(mol-K)
C. AH = 8.7 kJ/mol, AS = 0.008 kJ/(mol-K)
D. AH = 205 kJ/mol, AS = 0.210 kJ/(mol-K)

Answers

Answer:

A

∆H = 28 kJ/mol, ∆S = 0.109 kJ/(mol-k)

Explanation:

A P E X

The spontaneous reaction at 298 K is the one having

ΔH = 28 kJ/mol, ΔS = 0.109 kJ/(mol-K)

We know the formula of Gibb's free energy as-

ΔG = ΔH - TΔS

ΔG = 28 - (298 × 0.109)

ΔG = -4.48

If a reaction is spontaneous, change in Gibb's free energy is negative and change in entropy is positive.

Therefore, The spontaneous reaction at 298 K is the one having

ΔH = 28 kJ/mol, ΔS = 0.109 kJ/(mol-K)

4.62 grams of oxygen and 2.98 grams of carbon monoxide are placed in a closed

reaction vessel and the mixture is ignited. Combustion occurs until one of the

gases is totally consumed.

1. Identify the limiting reagent and the excess reagent

2. Determine the amount of excess reagent.

3. Calculate the grams of carbon dioxide produced.

Answers

Answer: 1. [tex]CO[/tex] is the limiting reagent and [tex]O_2[/tex] is the excess reagent.

2. 2.91 g of excess reagent

3. 4.66 g of carbon dioxide produced.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} CO=\frac{2.98g}{28g/mol}=0.106moles[/tex]

[tex]\text{Moles of} O_2=\frac{4.62g}{32g/mol}=0.144moles[/tex]

[tex]O_2+2CO\rightarrow 2CO_2[/tex]  

According to stoichiometry :

2 moles of [tex]CO[/tex] require = 1 mole of [tex]O_2[/tex]

Thus 0.106 moles of [tex]CO[/tex] will require=[tex]\frac{1}{2}\times 0.106=0.053moles[/tex]  of [tex]O_2[/tex]

Thus [tex]CO[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.

Amount of excess reagent = ( 0.144-0.053) moles = 0.091 moles

Mass of excess reagent [tex]O_2=moles\times {\text {Molar mass}}=0.091moles\times 32g/mol=2.91g[/tex]

As 2 moles of [tex]CO[/tex] give = 2 moles of [tex]CO_2[/tex]

Thus 0.106 moles of [tex]CO[/tex] give =[tex]\frac{2}{2}\times 0.106=0.106moles[/tex]  of [tex]CO_2[/tex]

Mass of [tex]CO_2=moles\times {\text {Molar mass}}=0.106moles\times 44g/mol=4.66g[/tex]

How much heat (in kJ) would need to be removed to cool 150.3 g of water from 25.60°C to -10.70°C?

Answers

Answer:

Q = -22.9 kJ

Explanation:

Given that,

Mass of water, m = 150.3 g

Water gets cool from 25.60°C to -10.70°C.

The specific heat of water, c = 4.2 J/g°C

The formula for heat needed is given by :

[tex]Q=mc\Delta T\\\\Q=150.3\times 4.2 \times (-10.7-25.6)\\\\Q=-22914.738\\\\or\\\\Q=22.9\ kJ[/tex]

So, 22.9 kJ of heat is needed to be removed to cool.

Ammonium perchlorate is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas , chlorine gas , oxygen gas , water , and a great deal of energy. What mass of water is produced by the reaction of of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

Answers

Answer:

2.9 g of water are produced by 9.6 g of ammonium perchlorate

Note: The question is incomplete. The complete question is given below:

Ammonium perchlorate (NH₄ClO₄) is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) , and a great deal of energy. What mass of water is produced by the reaction of 9.6 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

Explanation:

The reaction of ammonium perchlorate (NH₄ClO₄) to produce nitrogen gas (N₂) , chlorine gas (Cl₂), oxygen gas (O₂), water (H₂O) is shown in the balanced chemical equation given below:

2 NH₄ClO₄ →  N₂ +  Cl₂ + 2 O₂ + 4 H₂O

From the equation, 2 moles of ammonium perchlorate produces 4 moles of water, i.e. mole ratio of NH₄ClO₄ to H₂O = 2 : 4 = 1 : 2

molar mass of ammonium perchlorate, NH₄ClO₄ = (14 + 4 * 1 + 35.5 +16 * 4) = 117.5

molar mass of water,  H₂O = (2 * 1 + 16) = 18.0 g

mass of water produced = moles of ammonium perchlorate * 2 * molar mass of water

moles of perchlorate = mass / molar mass = 9.6/117.5

mass of water produced = 9.6/117.5 * 2 * 18.0 g  = 2.94 g of water

Therefore, 2.9 g of water are produced by 9.6 g of ammonium perchlorate

Combustion of hydrocarbons such as octane (C_8H_18) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.
1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid octane into gaseous carbon dioxide and gaseous water.
2. Suppose 0.330 kg of octane are burned in air at a pressure of exactly 1 atm and a temperature of 10.0 ?C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits.

Answers

Answer: 1. [tex]2C_8H_{18}(l)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)[/tex]

2. The volume of carbon dioxide gas that is produced is 537 L

Explanation:

1. Combustion is defined as the type of chemical reaction where a hydrocarbon is combusted in the presence of oxygen to give carbon dioxide and water.

The balanced reaction for combustion of octane is:

[tex]2C_8H_{18}(l)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)[/tex]

2.

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]   [tex]\text{Moles of octane}=\frac{0.330\times 1000g}{114.23g/mol}=2.89moles[/tex]

According to stoichiometry:

2 moles of octane produce = 16 moles of carbon dioxide

2.89 moles of octane produce = [tex]\frac{16}{2}\times 2.89=23.1moles[/tex] of carbon dioxide

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1 atm

V = Volume of gas = ?

n = number of moles = 23.1

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]10.0^0C=(10+273)K=283K[/tex]

[tex]V=\frac{nRT}{P}[/tex]

[tex]V=\frac{23.1\times 0.0821Latm/K mol\times 283K}{1atm}=537L[/tex]

Thus the volume of carbon dioxide gas that is produced is 537 L

8.07. 1024 particles
04.49. 1022 particles
6.02. 1024 particles
6.02. 1023 particles

Answers

Answer:

[tex]\boxed {\boxed {\sf 8.07 *10^{24} \ particles}}[/tex]

Explanation:

To convert from moles to representative particles, Avogadro's number: 6.02*10²³ is used. This number tells us the amount of particles in 1 mole of a substance. We can use it as a ratio.

[tex]\frac {6.02*10^{23} \ particles}{1 \ mol \ CO_2}}[/tex]

Multiply by the given number of moles.

[tex]13.4 \ mol \ CO_2 *\frac {6.02*10^{23} \ particles}{1 \ mol \ CO_2}}[/tex]

The moles of carbon dioxide will cancel out.

[tex]13.4 *\frac {6.02*10^{23} \ particles}{1}}[/tex]

The denominator of 1 can be ignored and this becomes a simple multiplication problem.

[tex]13.4 * {6.02*10^{23} \ particles[/tex]

[tex]8.0668*10^{24} \ particles[/tex]

The original number of moles has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 6 in the thousandth place tells us round the 6 to a 7.

[tex]8.07 *10^{24} \ particles[/tex]

13.4 moles of carbon dioxide has approximately 8.07*10²⁴ particles.

Ni 12.7g
CO 1.98g

Calculate the value of the equilibrium constant for this reaction. Round your answer to significant digits.

Answers

Answer: The value of the equilibrium constant for this reaction is [tex]2.8\times 10^{-5}[/tex]

Explanation:

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

Moles of  [tex]Ni(CO)_4[/tex] = [tex]\frac{0.597g}{170.7g/mol}=0.0035moles[/tex]

Moles of  [tex]Ni[/tex] =  [tex]\frac{12.7g}{58.7g/mol}=0.216moles[/tex]

Moles of  [tex]CO[/tex] =  [tex]\frac{1.98g}{28.01g/mol}=0.071moles[/tex]

Volume of solution = 2.7 L

Equilibrium concentration of [tex]Ni(CO)_4[/tex] = [tex]\frac{0.0035mol}{2.7L}=1.29\times 10^{-3}M[/tex]

Equilibrium concentration of [tex]Ni[/tex] = [tex]\frac{0.216mol}{2.7L}=0.08M[/tex]

Equilibrium concentration of [tex]CO[/tex] = [tex]\frac{0.071mol}{2.7L}=0.026M[/tex]

The given balanced equilibrium reaction is,

                            [tex]Ni(CO)_4\rightleftharpoons Ni+4CO[/tex]

The expression for equilibrium constant for this reaction will be,

[tex]K_c=\frac{[Ni]^1\times [CO]^4}{[Ni(CO_4]^1}[/tex]

Now put all the given values in this expression, we get :

[tex]K_c=\frac{(0.08)^1\times (0.026)^4}{(1.29\times 10^{-3})^1}[/tex]

[tex]K_c=2.8\times 10^{-5}[/tex]

Thus the value of the equilibrium constant for this reaction is [tex]2.8\times 10^{-5}[/tex]

3.00 g of a fuel (MW = 650.0 g/mol) is combusted in a bomb calorimeter. The temperature of the calorimeter increases by 25.0 degrees Celsius. The heat capacity for the calorimeter has been determined to be 9.001kJ/C. What is the heat of reaction (in kJ/mol)?​

Answers

Answer:

-4.88 × 10⁴ kJ/mol

Explanation:

Step 1: Calculate the heat gained by the calorimeter (Qcal)

We will use the following expression.

Qcal = C × ΔT

where,

C: heat capacity of the calorimeterΔT: temperature change

Qcal = 9.001 kJ/°C × 25.0°C = 225 kJ

Step 2: Calculate the heat released by the fuel

According to the law of conservation of energy, the sum of the heat released by the fuel (Qf) and the heat absorbed by the calorimeter is zero.

Qf + Qcal = 0

Qf = -Qcal = -225 kJ

Step 3: Calculate the heat of reaction in kJ/mol

3.00 g of a fuel (MW = 650.0 g/mol) released 225 kJ of heat. The heat of reaction is:

-225 kJ/3.00 g × 650.0 g/mol = -4.88 × 10⁴ kJ/mol

It is also used as a safe replacement for mercury in thermometers as it melts at 29.8 °C and has a heat of fusion of 5.59 kJ/mol. What is the entropy change of 22 g of gallium in J/K as it melts when placed on a surface at 29.8°C?

Answers

Answer:

4.255 J/ K

Explanation:

Given data :

mass of Gallium = 16 gm

molar mass = 69.723 g/mol

hence no of moles = 16 / 69.723 = 0.23 moles --------- ( 1 )

Δh ( heat fusion ) = 5.59 KJ/mol

Temperature = 29.8°C = 302.8 k

Determine the entropy change of gallium

Δs ( entropy change ) =  heat fusion / temperature

 = ( 5.59 * 1000) J/mol / 302.8 = 18.46 J/k*mol

Hence entropy change of gallium

= Δs * no of Gallium moles

= 18.46 * 0.23 = 4.255 J/ k
