1. The correct formula of an ionic compound containing Al³⁺ and CO₃²⁻ is —
Show answer
Answer: C — Al₂(CO₃)₃
2. Which of the following orbital diagrams is incorrect because it violates Hund’s rule? Each option represents the filling of the 1s, 2s, and three 2p orbitals (2pₓ, 2pᵧ, 2p_z). Hund’s rule states that electrons occupy degenerate orbitals singly with parallel spins before pairing.
Show answer
Answer: B — Electrons fill 1s and 2s, then two electrons paired in one 2p orbital while the other 2p orbitals are empty
3. The rate of a certain reaction increases with temperature. According to the data, at 20 °C the rate is approximately half of the rate at 40 °C. To double the rate of the reaction starting at 20 °C, the temperature must be increased by approximately —
Show answer
Answer: B — 20 °C
4. Aluminum + sulfuric acid → aluminum sulfate + hydrogen gas Which of the following is the balanced chemical equation for the reaction shown above?
Show answer
Answer: B — 2Al + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂
