What is the specific heat capacity for a 5 g sample of metal that absorbs
100 Joules of heat energy when its temperature changes from 10 degrees
C to 40 degrees C?*
A) 15, 000 J/gC
B) 2 J/go
C)0.67 J/gC
D) 0.50 J/go

Answers

Answer 1

Answer:

The specific heat capacity is 0.67 [tex]\frac{J}{g*C}[/tex]

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

The amount of heat that a body receives or transmits is determined by the following expression:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

This expression indicates that between heat and temperature there is a direct proportional relationship.

In this case:

Q= 100 Jc= ?m= 5 gΔT= Tfinal - Tinitial= 40 °C - 10 °C= 30 °C

Replacing:

100 J= c*5 g* 30°C

Solving:

[tex]c=\frac{100 J}{5 g* 30C}[/tex]

c= 0.67 [tex]\frac{J}{g*C}[/tex]

The specific heat capacity is 0.67 [tex]\frac{J}{g*C}[/tex]

A gas occupies a volume of 2.45 L at a pressure of 1.03 atm. What volume will the
gas occupy if the pressure changes to 0.980 atm and the temperature remains
unchanged? Show your work in the space below. *​

Answers

Answer:

2.58 L

Explanation:

Please see the step-by-step solution in the picture attached below.

Hope this answer can help you. Have a nice day!

At constant temperature, if the pressure of the gas decreases to the given value, the volume increases to 2.58L.

What is Boyle's law?

Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.

Given the data in the question

Initial volume V₁ = 2.45LInitial pressure P₁ = 1.03atmFinal pressure P₂ = 0.980 atmFinal volume V₂ = ?

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

V₂ = ( 1.03atm × 2.45L ) / 0.980atm

V₂ = 2.5235Latm / 0.980atm

V₂ = 2.58L

Therefore, at constant temperature, if the pressure of the gas decreases to the given value, the volume increases to 2.58L.

Suppose the yield of the first step is 71.% and the yield of the second step is 72.%. Calculate the mass of oxygen required to make 7.0 kg of iron.
Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

Answers

Answer:

5.9 kg  

Explanation:

We must work backwards from the second step to work out the mass of oxygen.

1. Second step

Mᵣ:                                     55.84

            Fe₂O₃ + 3CO  ⟶  2Fe  +  3CO₂

m/kg:                                    7.0

(a) Moles of Fe

[tex]\text{Moles of FeO} = \text{7000 g Fe} \times \dfrac{\text{1 mol Fe}}{\text{55.84 g Fe}} = \text{125 mol Fe}[/tex]

(b) Moles of CO

[tex]\text{Moles of CO} = \text{125 mol Fe} \times \dfrac{\text{3 mol CO}}{\text{2 mol Fe}} = \text{188 mol CO}[/tex]

However, this is the theoretical yield.

The actual yield is 72. %.

We need more CO and Fe₂O₃ to get the theoretical yield of Fe.

(c) Percent yield

[tex]\begin{array}{rcl}\text{Percent yield} &=& \dfrac{\text{ actual yield}}{\text{ theoretical yield}} \times 100 \, \%\\\\ 72. \, \% & = & \dfrac{\text{188 mol}}{\text{actual yield}} \times 100 \,\%\\\\0.72 &= &\dfrac{\text{188 mol}}{\text{actual yield}}\\\\\text{Actual yield} & = & \dfrac{\text{188 mol}}{0.72}\\& = & \textbf{261 mol}\\\\\end{array}[/tex]

We must use 261 mol of CO to get 7.0 kg of Fe.

2. First step

Mᵣ:                32.00

            2C   +  O₂   ⟶  2CO

n/mol:                             261

(a) Moles of O₂

[tex]\text{Moles of O}_{2} = \text{261 mol CO} \times \dfrac{\text{1 mol O}_{2}}{\text{2 mol CO}} = \text{131 mol O}_{2}[/tex]

(b) Mass of O₂

[tex]\text{Mass of O}_{2}= \text{131 mol O }_{2} \times \dfrac{\text{32.00 g O}_{2}}{\text{1 mol O}_{2}} = \text{4180 g O}_{2}[/tex]

However, this is the theoretical yield.

The actual yield is 71. %.

We need more C and O₂ to get the theoretical yield of CO.

(c) Percent yield

[tex]\begin{array}{rcl}71. \, \% & = & \dfrac{\text{188 mol}}{\text{actual yield}} \times 100 \,\%\\\\0.71 &= &\dfrac{\text{4180 g}}{\text{actual yield}}\\\\\text{Actual yield} & = & \dfrac{\text{4180 g}}{0.71}\\\\& = & \text{5900 g}\\& = & \textbf{5.9 kg}\\\end{array}[/tex]

We need 5.9 kg of O₂ to produce 7.0 kg of Fe.

Answers

Answer: 780 kcal are required to produce 12.00 mol of [tex]Cl_2O_7[/tex]

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and written along with reactants.

The balanced chemical reaction is:

[tex]2Cl_2(g)+7O_2(g)+130kcal\rightarrow 2Cl_2O_7(g)[/tex]

According to stoichiometry :

2 moles of [tex]Cl_2O_7[/tex] are produced by absorption of energy = 130 kcal

Thus 12.00 moles of [tex]Cl_2O_7[/tex] are produced by absorption of energy = [tex]\frac{130}{2}\times 12.00=780kcal[/tex]

Thus 780 kcal are required to produce 12.00 mol of [tex]Cl_2O_7[/tex]

Answers

Answer:

28.98°C

Explanation:

Mass = 52g

Initial temperature (T1) = 10°C

Final temperature (T2) = ?

Heat energy (Q) = 4130J

Specific heat capacity of water = 4.184J/g°C

Heat energy (Q) = mc∇T

Q = heat energy

M = mass of the substance

C = specific heat capacity of the substance

∇T = change in temperature (T2 - T1)

Q = mc∇T

4130 = 52 * 4.184 * (T2 - 10)

4130 = 217.568 * ( T2 - 10)

4130 = 217.568T2 - 2175.68

217.568T2 = 4130 + 2175.68

217.57T2 = 6305.68

T2 = 6305.68 / 217.57

T2 = 28.98°C

Final temperature is 28.98°C

Explanation:

A student investigates a pure metal, X. The student takes a 100.0 g piece of metal X, heats it
to 500.0°C, then places it on a 1000.0 g block of ice at 0.0°C. The ice partially melts, and
the final temperature of the metal, ice, and melted water is 0.0°C. The student calculates the
experimental value of the specific heat capacity of metal X and records it as
0.90 J/(g • °C).
(C) Calculate the magnitude of the energy change of metal X during the experiment.
(d) Calculate the mass of ice melted by metal X. (The enthalpy of fusion of ice is 330J/g.
(e) A student claims that the energy transferred to the ice breaks the polar-covalent O-H
bonds found between atoms within water molecules. Do you agree or disagree with this
claim? Justify your answer.

Answers

Answer: The answer would be D

Explanation:

The magnitude of the energy change of metal X during the experiment is 6500 J, and the mass of ice melted by metal X is 19.7 g and the claim of the student is correct.

What are changes in ice?

The magnitude of energy change of metal is equal to the mass of metal x specific heat capacity of metal x temp. difference

= 100 g x 0.13 J / ( g- oC) x (500 - 0) oC

= 6500 J

According to the question, the enthalpy of the fusion of ice is 330 J / g

Thus 330 J heat is used to melt 1 g of ice

So 6500 J heat is used to melt = 1 x (6500 / 330) = 19.7 g ice

Although hydrogen bonds can form in both a solid and a liquid state, they are more stronger in the solid state. In order to partially dissolve its hydrogen bonds and turn solid ice into liquid water, whatever heat is applied to it is therefore used.

Therefore, the student's assertion is true.

Answers

Answer:

19.47%

Explanation:

The percentage by mass of [tex]H_2SO_4[/tex] would be 19.47%.

The percentage by mass of a substance in solution is calculated as:

   [tex]\frac{mass of substance}{mass of substance + water} * 100%[/tex]

Given that the mole fraction of [tex]H_2SO_4[/tex] = 0.432

The total number of mole fraction of a solution = 1

Hence, mole fraction of water = 1 - 0.432 = 0.568

Mass of water = molar mass x mole

                              = 98.079 x 0.432 = 42.37 g

Mass of [tex]H_2SO_4[/tex] = molar mass x mole

                          = 18.02 x 0.568 = 10.24 g

Hence,

%mass of [tex]H_2SO_4[/tex] = [tex]\frac{10.24}{10.24 + 42.37} * 100[/tex]

The strong nuclear force is always smaller than the electrostatic force true or false

Answers

Answer:

False

Explanation:

The Strong Nuclear Force is defined as an attractive force between neutrons and protons which is responsible to hold the nucleus together.

Electrostatic force is the repulsive or attractive force between two electrically charged objects.

Strong nuclear force is always greater than electrostatic force but changes with the distance. Strong nuclear attraction keeps the nucleus of an atom together in a small space as well which is stronger  than their electrostatic repulsion.

it is said that, the strong nuclear force is the strongest force in the universe.

Hence, the given statement is false.

Answer:

False

Explanation:

Strong nuclear forces are much higher than the electrostatic repulsive force. In case if these strong nuclear forces would have not been there, then the nucleus would have disintegrated. This is so because only gravity cannot keep hold on these particles. The nuclear force varies with the size of nucleus. As the size of nucleus increases, the electrostatic repulsion becomes greater

Hence, the given statement is false
