Predict the products for the reaction of the following set of reactants. Mg(s) + Cl₂(g) $\to$ A) MgCl(s) B) MgCl₂(s) C) MgCl(l) D) MgCl₂(l) E) MgCl₂(aq)

Question

Quizplus · Accepted Answer

When magnesium reacts with hydrogen chloride (HCl) gas, it undergoes a single displacement reaction to form magnesium chloride (MgCl2) and hydrogen gas (H2). Therefore, the correct formula for the product is MgCl2. The (s) in the product indicates that it is a solid. However, MgCl2 can also exist in liquid and aqueous states, but that would depend on the conditions of the reaction. Therefore, options A, C, D, and E can all be potential products under different conditions. However, option B, MgCl2 as a solid, is the most suitable choice.
