Answer 1

C. aluminum + hydrochloric acid → aluminum chloride + hydrogen

Step-by-step explanation:

Usually reactants are written on the left and products on the right side.

The question says aluminum and hydrochloric acid are the reactants and aluminum chloride and hydrogen are the products, thus
