Chemistry 30 Diploma Practice Questions - Alberta Grade 12 Diploma Examination - Chemistry 30 Exam - Chemistry 30 Diploma Practice Questions - Alberta Grade 12 Diploma Examination

Question 1

In Alberta Chemistry 30, an exothermic reaction is best described by which statement about enthalpy change?

The enthalpy of products is greater than the enthalpy of reactants, so delta H is positive Energy is absorbed from the surroundings, so the surroundings cool down The system gains potential energy and delta H equals zero The enthalpy of products is less than the enthalpy of reactants, so delta H is negative

Correct Answer:

The enthalpy of products is less than the enthalpy of reactants, so delta H is negative

Question 2

The molar enthalpy of combustion of methane is -802.3 kJ/mol. How much energy is released when 2.00 mol of methane is completely combusted?

-401.2 kJ -802.3 kJ -1604.6 kJ -1204.5 kJ

Correct Answer:

-1604.6 kJ

Question 3

In a calorimetry experiment, the quantity of heat absorbed by water is calculated using which equation?

q = m x c x delta T q = n x delta H q = c x delta T / m q = m x delta T / c

Correct Answer:

q = m x c x delta T

Question 4

A 100.0 g sample of water is heated from 20.0 degC to 45.0 degC. Using c = 4.19 J/(g.degC), how much heat energy was absorbed?

1.05 x 10^4 J 8.38 x 10^3 J 1.88 x 10^4 J 4.19 x 10^3 J

Correct Answer:

1.05 x 10^4 J

Question 5

On a potential energy diagram, the activation energy of the forward reaction is represented by the difference between which two points?

The energy of the products and the energy of the reactants The energy of the activated complex (peak) and the energy of the products The energy of the activated complex (peak) and the energy of the reactants The energy of the reactants and the energy of the products at equilibrium

Correct Answer:

The energy of the activated complex (peak) and the energy of the reactants
