Answer:
D. zinc and hydrochloric acid.
Step-by-step explanation:
Step 1: The balanced equation:
Zn + 2HCL → ZnCl2 + H2
Step 2:
All chemical reactions involve both reactants and products. Reactants are substances that start a chemical reaction, and products are substances that are produced in the reaction.
This means the substances on the left side, Zinc (Zn) and hydrochloric acid (HCl) are the reactants and will react with eachother, to form the products Zinc chloride (ZnCl2) and hydrogen gas (H2).
Option A: is not correct because zinc chloride and hydrogen are the products
Option B: is not correct because there is no hydrogen carbonate in the reaction
Option C: is not correct because there is no zinc chlorate, neither water in the reaction
The correct answer is D. zinc and hydrochloric acid.
