Answers

Answer 1

Answer: The final temperature is 248.7 K

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.

Mathematically,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.

[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.

We are given:

[tex]P_1=951.72kPa\\T_1=653.34K\\P_2=362.29kPa\\T_2=?[/tex]

Putting values in above equation, we get:

[tex]\frac{951.72}{653.34}=\frac{362.29}{T_2}\\\\T_2=248.7K[/tex]

Thus the final temperature is 248.7 K

How many grams of CO2 will be produced when 8.50 g of methane react with 15.9 g of O2, according to the following reaction? CH4(g) +2 O2(g) = CO2(g) +2 H2O(g)

Answers

Taking into account the reaction stoichiometry, 10.93 grams of CO₂ are formed when 8.50 g of methane react with 15.9 g of O₂.

Reaction stoichiometry

In first place, the balanced reaction is:

CH₄ + 2 O₂  → CO₂ + 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

CH₄: 1 mole O₂: 2 molesCO₂:  1 moleH₂O: 2 moles

The molar mass of the compounds is:

CH₄: 16 g/moleO₂: 32 g/moleCO₂:  44 g/moleH₂O: 18 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

CH₄: 1 mole ×16 g/mole= 16 gramsO₂: 2 moles ×32 g/mole= 64 gramsCO₂:  1 mole ×44 g/mole= 44 gramsH₂O: 2 moles ×18 g/mole=36 grams

Limiting reagent

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

Limiting reagent in this case

To determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 16 grams of CH₄ reacts with 64 grams of O₂, 8.50 grams of CH₄ reacts with how much mass of O₂?

[tex]mass of O_{2} =\frac{8.50 grams of CH_{4}x64 grams of O_{2} }{16grams of CH_{4}}[/tex]

mass of O₂= 34 grams

But 34 grams of O₂ are not available, 15.9 grams are available. Since you have less mass than you need to react with 8.50 grams of CH₄, O₂ will be the limiting reagent.

Mass of CO₂ formed

The following rule of three can be applied: if by reaction stoichiometry 64 grams of O₂ form 44 grams of CO₂, 15.9 grams of O₂ form how much mass of CO₂?

[tex]mass of CO_{2} =\frac{15.9 grams of O_{2}x44 grams of CO_{2} }{64grams of O_{2}}[/tex]

mass of CO₂= 10.93 grams

Then, 10.93 grams of CO₂ are formed when 8.50 g of methane react with 15.9 g of O₂.

Answers

Answer:

9.21 kJ is the enrgy required to vaporize 11.0 grams of ethanol.

Explanation:

Energy of vaporization can be stated as 38.6 kj/mole for ethanol.  ["It takes 38. 6 kj of energy to vaporize 1. 00 mol of ethanol"]

11.0 grams of ethanol is not 1 mole.  Calculate the moles of ethanol by dividing t=it's mass by its molar mass:

What is dissolution of a substance in water?

Water is known as the universal solvent. Water is a polar substance hence it is often used to dissolve polar substances. It has a dipole and being that there is a high degree of electronegativity difference between the oxygen and the hydrogen atoms in water, it is feasible that the degree of hydrogen bonding between the two is high.

We know that dissolution is favored when there will be an increase in entropy as a result of that, that is; if more particles will appear. Now we know that ΔG = ΔH - TΔS.

Answers

The volume of water that must be add is 20 mL. Volume of water that must add is new volume after dilution minus initial volume.

How to determine the volume that must be add?

As per data given:

Initial volume (V1) = 40 mL = 0.040 L

Initial molarity(C1) = 9.0 M

New molarity (C2)= 6.0 M

As we want to know to the new volume of water(V2). We have to use dilution formula where the formula is C1 x V1 = C2 x V2. So, the calculation would be:

9.0 x 0.040 = 6.0 x V2

V2 = 0.06 L

V2 = 60 mL

Since the addition water is the difference between V2 and V1:

Volume add = V2 -V1

Answers

In the electrolysis of water,  3490 hour will it take to produce 165.0 L of H2 at 1.0 atm and 273 K using an electrolytic cell through which the current is 113.0 mA.

What is Ideal Gas Law ?

The ideal gas law states that the pressure of gas is directly proportional to the volume and temperature of the gas.

It is expressed as

PV = nRT

where,

P = Pressure

V = Volume in liters

n = number of moles of gas

R = Ideal gas constant

T = Temperature in kelvin

Here,

P = 1.0 atm

V = 165.0 L

R = 0.0821 atm. L/mol.K (Ideal gas constant)

T = 273 K

n = ?

Now put the value in above expression, we get

PV = nRT

1.0 atm × 165.0 L = n × 0.0821 atm. L/mol.K × 273 K

165.0 atm. L = n × 22.4  atm. L/mol

[tex]n = \frac{165.0\ \text{atm. L}}{22.4\ \text{atm. L/mol}}[/tex]

n = 7.36 mol

The reaction is

2H⁺ + 2e⁻ → H₂

1 mol of electrons is produced from 96500 C

So,

[tex]96500 \frac{C}{\text{mol} \times e} \times 2e \times 7.36\ \text{mol}[/tex]

= 1,420,480 C

Convert milliampere to C/s

1mA = 0.001 C/s

113.0 mA = 113.0 × 0.001

               = 0.113 c/s

What is relationship between current, charge and time ?

The relation between current, charge and time is expressed as:

[tex]I = \frac{Q}{t}[/tex]

where,

I = Current

Q = Charge in Coulomb

t = time

Now put the value in above formula we get

[tex]I = \frac{Q}{t}[/tex]

  [tex]= \frac{1,420,480\ C}{0.113\ C/s}[/tex]

  = 12,570,619.469 s

  = 3490 hour

Thus from the above conclusion we can say that In the electrolysis of water,  3490 hour will it take to produce 165.0 L of H2 at 1.0 atm and 273 K using an electrolytic cell through which the current is 113.0 mA.

The number of mole of Ag formed from the reaction of 8.0 moles of AgNO₃ and 5.0 moles of Zn, given the chemical reaction is 8 moles

How do I determine the number of mole of Ag formed?

To know the number of mole of Ag formed, we'll begin by obtaining the limiting reactant. Details below:

From the balanced equation above,

2 moles of AgNO₃ reacted with 1 mole of Zn

Therefore,

8 moles of AgNO₃ will react with = (8 × 1) / 2 = 4 moles of Zn

From the above calculation, 8 moles of AgNO₃ requires only 4 moles out of 5 moles of Zn given. Thus, AgNO₃ is the limiting reactant

Finally, we shall determine the number of moles of Ag formed. This is shown below:

From the balanced equation above,

2 moles of AgNO₃ reacted to produce 2 moles of Ag

Therefore,

8 moles of AgNO₃ will also react to produce 8 moles of Ag
