1. Sarah also wants to offer her vegan guests a slightly more filling option such as a light soup with some biscuits. Which two chapters of the cookbook should she consult?

• A. Chapter II and Chapter III
• B. Chapter I and Chapter III
• C. Chapter II and Chapter IV
• D. Chapter V and Chapter VI

Correct answer: C

Rationale: Sarah wants to offer her vegan guests a slightly more filling option such as a light soup with some biscuits. Chapter II of the cookbook covers light soups, making it a suitable choice for soup ideas. Chapter IV focuses on baking and bread recipes, including biscuits. By consulting Chapter II for soup recipes and Chapter IV for biscuit recipes, Sarah can find appropriate dishes for her vegan guests. Choice A (Chapter II and Chapter III) is incorrect because Chapter III does not cover biscuits. Choice B (Chapter I and Chapter III) is incorrect as biscuits are not part of Chapter I. Choice D (Chapter V and Chapter VI) is incorrect because these chapters do not contain relevant recipes for a light soup with biscuits.

2. Two even integers and one odd integer are multiplied together. Which of the following could be their product?

• A. 3.75
• B. 9
• C. 16.2
• D. 24

Correct answer: D

Rationale: When multiplying two even integers and one odd integer, the product will always be even. This is because multiplying any number of even integers will always result in an even number. Therefore, the only possible product from the given options is 24, as it is the only even number listed. Choices A, B, and C are incorrect as they are all odd numbers, and the product of two even integers and one odd integer will never result in an odd number.

3. Which of the following factors would NOT affect the solubility of a solid solute in a liquid solvent?

• A. Temperature
• B. Pressure
• C. Particle size
• D. Nature of the solute and solvent

Correct answer: B

Rationale: Pressure does not typically affect the solubility of a solid solute in a liquid solvent. Solubility is primarily influenced by factors such as temperature, particle size, and the nature of the solute and solvent. Increasing pressure generally has a minimal effect on the solubility of solids in liquids. The impact of pressure on solubility is more significant for gases in liquids rather than solids in liquids. Therefore, option B is the correct answer. Options A, C, and D directly impact the solubility of a solid solute in a liquid solvent. Temperature affects the solubility as it changes the kinetic energy of particles, particle size can impact the surface area available for interaction between solute and solvent, and the nature of the solute and solvent influences their intermolecular interactions and compatibility.

4. What property of a substance remains constant regardless of changes in its shape or size?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: A

Rationale: Mass is a measure of the amount of matter in an object and remains constant regardless of changes in its shape or size. Weight, density, and volume can all change depending on the conditions, but mass remains the same. For example, if you have a piece of clay and you shape it into a ball or flatten it into a pancake, the amount of clay (mass) will remain the same, even though the shape and size have changed. Weight is the force acting on an object due to gravity, which can vary depending on the gravitational pull. Density is the mass per unit volume, so it changes with variations in volume. Volume is the amount of space occupied by an object, which can change if the shape or size of the object is altered.

5. Imagine you have an element with atomic number 11 and mass number 23. How many neutrons does it have?

• A. 11
• B. 12
• C. 23
• D. 21

Correct answer: B

Rationale: - The atomic number (Z) of an element is the number of protons in its nucleus. In this case, the element has an atomic number of 11. - The mass number (A) of an element is the sum of its protons and neutrons. Given that the mass number is 23 and the atomic number is 11, we can calculate the number of neutrons by subtracting the atomic number from the mass number: Neutrons = Mass number - Atomic number = 23 - 11 = 12. - Therefore, the element with atomic number 11 and mass number 23 has 12 neutrons.
