Hi this question is on my study guide and I want to make sure I get to the right answer and know why.

Explain why the following reaction goes to completion instead of to equilibrium.
Mg(s) + 2HCL(aq) -> MgCl2 (aq) + H2(g) (subscript 2 after MgCl2 and H2)

1 answer

Reactions go to completion for three (3) reasons.
1. A gas is formed. Here H2 gas is formed.
2. A ppt (a solid; i.e., an insoluble substance) is formed.
3. A weak electrolyte is formed.
