Question 1

Which of the following best describes the key concept of 'Atoms and forces' in the Cambridge International AS & A Level Chemistry syllabus?

Accepted Answer

Matter is built from atoms interacting and bonding through electrostatic forces, which influences both physical and chemical properties.

Question 2

A student is asked to predict the products of a chemical reaction using patterns in chemical behavior. Which key concept from the syllabus is being applied?

Accepted Answer

Patterns in chemical behaviour and reactions

Question 3

Which of the following is a direct application of the concept 'Energy changes' in chemical reactions?

Accepted Answer

Calculating the enthalpy change $$\Delta H$$ for a reaction to determine its feasibility.

Question 4

A scientist uses experimental data to build a model of the structure and reactivity of a new material. Which key concept is most relevant?

Accepted Answer

Experiments and evidence

Question 5

Which equation is used to calculate the energy change when a chemical reaction occurs at constant pressure?

Accepted Answer

$$\Delta H = \Delta U + P\Delta V$$

Question 6

A student observes that sodium reacts vigorously with water, producing hydrogen gas and a strong alkaline solution. Which syllabus concept does this observation best illustrate?

Accepted Answer

Patterns in chemical behaviour and reactions

Question 7

Which of the following is NOT a skill developed by Cambridge International AS & A Level Chemistry according to the syllabus?

Accepted Answer

Memorizing chemical formulas without understanding their application

Question 8

Which formula would you use to calculate the amount of heat absorbed by 100 g of water when its temperature increases by $$10 ^\circ C$$? (Specific heat capacity of water $$c = 4.18 	ext{ J g}^{-1} 	ext{K}^{-1})$$

Accepted Answer

$$q = mc\Delta T$$

Question 9

Which of the following best explains why understanding chemical bonds is important in predicting the properties and uses of materials?

Accepted Answer

The strength and type of chemical bonds determine the structure, reactivity, and physical properties of materials.

Question 10

A student is asked to explain why ice floats on water. Which concept and property should they use?

Accepted Answer

Atoms and forces; hydrogen bonding causes ice to be less dense than liquid water.

Question 11

Which of the following is a correct statement about the role of experiments in chemistry according to the syllabus?

Accepted Answer

Experiments are used to build models and test theories about the structure and reactivity of materials.

Question 12

Which equation is used to relate the pressure, volume, and temperature of an ideal gas?

Accepted Answer

$$PV = nRT$$

Question 13

A student is tasked with evaluating the feasibility of a chemical reaction. Which concept and calculation should they use?

Accepted Answer

Energy changes; calculate $$\Delta G ($$Gibbs free energy) to determine spontaneity.

Question 14

Which of the following is a transferable skill developed by studying Cambridge International AS & A Level Chemistry?

Accepted Answer

Applying scientific thinking to unfamiliar situations

Question 15

Which of the following best describes the relationship between chemical bonds and energy changes in reactions?

Accepted Answer

Breaking chemical bonds requires energy, while forming new bonds releases energy.

Question 16

A student is asked to use the periodic table to predict the reactivity of Group 1 elements. Which concept is being applied?

Accepted Answer

Patterns in chemical behaviour and reactions

Question 17

Which of the following is a correct statement about the Cambridge learner profile for Chemistry?

Accepted Answer
