Answer

Explanation:

Step1: Identify reactants and products

Reactants are 2 HCl (aqueous) and solid Zn. Products are ZnCl₂ (aqueous) and H₂ gas.

Step2: Check stoichiometry and phases

For every 1 Zn atom reacting with 2 HCl molecules, 1 ZnCl₂ molecule and 1 H₂ molecule are formed. Also, phases should match given in problem.

Answer:

C. 2HCl (aq) + Zn (s) → ZnCl₂ (aq) + H₂ (g)
