1. In a reversible reaction at equilibrium, what does Le Chatelier's principle predict if pressure is increased?

✓ The reaction shifts to the side with fewer moles of gas

Le Chatelier's principle states that increasing pressure shifts equilibrium toward the side with fewer moles of gas to reduce pressure.

2. Identify the type of clause in bold: 'She left **before the show ended**.'

✓ Adverbial clause

'Before the show ended' is an adverbial clause modifying when she left.

3. An element has 17 protons and 18 neutrons. What is its mass number?

✓ 35

Mass number = protons + neutrons = 17 + 18 = 35.

4. Which type of bonding involves the sharing of electrons between two non-metal atoms?

✓ Covalent bonding

Covalent bonding occurs when two non-metal atoms share pairs of electrons to achieve stable electron configurations.

5. Active transport differs from diffusion because it:

✓ Moves substances against a concentration gradient using energy

Active transport uses ATP energy to move substances from low to high concentration — against the concentration gradient.

6. Decide which of the following sentences correctly employs verbs.

✓ An electrical phenomenon, such as static electricity or lightning, is fairly commonplace.

Subject-verb agreement dictates that a singular subject requires a singular verb. In option C, "An electrical phenomenon" is a singular subject, and the verb "is" correctly agrees with it. Options A, B, and D contain singular subjects ("layer," "training," "soil") paired incorrectly with plural verbs ("cover," "focus," "dry out").
