Answer
Products: $ZnCl_2(aq)$ and $H_2(g)$
Balanced equation:
$Zn(s) + 2HCl(aq) --\gt ZnCl_2(aq) + H_2(g)$
Work Step by Step
1. In a single replacement reaction, an element/compound switches places with an element in the other reacting compound.
In this case, the $Zn$ will replace the hydrogen in the reaction.
$Zn(s) + HCl(aq) --\gt ZnCl + H$
To balance the charge, there must be 2 $Cl$s with $Zn$. And hydrogen occurs as $H_2(g)$.
$Zn(s) + HCl(aq) --\gt ZnCl_2(aq) + H_2(g)$
2. Balance the equation.
- To balance the number of chlorine atoms, put a "1" in the front of $HCl$:
$Zn(s) + 2HCl(aq) --\gt ZnCl_2(aq) + H_2(g)$
