the answer is C.) Ca + HCl

Answer:

The correct answer is option d: CaCl2 + H2

Explanation:

Hello!

Let's solve this!

When the Ca + HCl is joined there is a replacement reaction in which Ca takes the place of H and to balance loads, we need two atoms of Cl.

The resulting reaction is CaCl2 + H2

The complete reaction is

Ca + 2HCl ---> CaCl2 + H2

We conclude that the correct answer is option d: CaCl2 + H2
