Identify what type of reaction is below. Also determine what coefficients that would balance the chemical equation. ___ HCl + ___Zn → ___ H2 + ___ZnCl2 A) Double Replacement; 2, 1, 1, 1 B) Single Replacement; 2, 1, 1, 1 C) Synthesis; 1, 2, 1, 2 D) Double Replacement; 1, 2, 1, 1

Single Replacement; 2, 1, 1, 1

Explanation:

2HCl + Zn → H2 + ZnCl2

In a single replacement reaction, one specie is replaced by another specie in a chemical reaction.

If we look at the reaction above, zinc metal reacted with hydrochloric acid. The reaction proceeds in such a manner that zinc replaces hydrogen in hydrochloric acid. This is a single replacement reaction because only one chemical specie is displaced in the reaction.

8 carbon atoms forming single bonds with 18 hydrogen atoms; a triple bond exists between the third and fourth carbon atom from the right

explanation:

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid
