Answer:
D. zinc and hydrochloric acid.
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) Â 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.
