How many electrons are transferred in the given reaction? Ni + 2 HCl → Ni Cl₂ + H₂ A) 0 B) 1 C) 2 D) 3 E) 4

Question

Quizplus · Accepted Answer

In the reaction, nickel (Ni) reacts with hydrochloric acid (HCl) to form nickel chloride (NiCl2) and hydrogen gas (H2). Nickel goes from a 0 oxidation state to a +2 oxidation state, meaning it loses 2 electrons. Hydrogen goes from a +1 oxidation state in HCl to a 0 oxidation state in H2, each hydrogen atom gains 1 electron, but since there are 2 hydrogen atoms involved, they collectively gain 2 electrons. Thus, 2 electrons are transferred in total.
