1. What literary device is used in the phrase "a heart of gold"?

• A. Metaphor
• B. Simile
• C. Hyperbole
• D. Personification

Correct answer: A

Rationale: The phrase directly compares someone's good nature to gold, making it a metaphor.

2. What is the coefficient of oxygen in the balanced chemical equation for the combustion of methane (CH4)?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: b

Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, so the coefficient of oxygen is 2.

3. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.

4. Which of the following is an example of a weak acid?

• A. Hydrochloric acid (HCl)
• B. Sulfuric acid (H2SO4)
• C. Acetic acid (CH3COOH)
• D. Nitric acid (HNO3)

Correct answer: C

Rationale: Weak acids only partially dissociate in water, releasing a lower concentration of hydrogen ions.

5. What is the difference between mass and weight?

• A. Mass is the force exerted on an object due to gravity, whereas weight is the amount of matter in an object.
• B. Mass is a measure of inertia, whereas weight is a measure of the force of gravity acting on an object.
• C. Mass is measured in pounds, whereas weight is measured in kilograms.
• D. Mass is a vector quantity, whereas weight is a scalar quantity.

Correct answer: b

Rationale: Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

6. Which of the following factors would increase the solubility of a gas in a liquid?

• A. Decreasing temperature
• B. Increasing pressure
• C. Decreasing surface area
• D. Increasing particle size

Correct answer: b

Rationale: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The other choices would typically decrease solubility.
