Answer

Explanation:

Step1: Balance chlorine atoms

On the right - hand side, there are 2 chlorine atoms in $ZnCl_2$. In $HCl$, to have 2 chlorine atoms, the coefficient of $HCl$ should be 2. So far, the equation is $Zn + 2HCl\rightarrow ZnCl_2+H_2$.

Step2: Check other atoms

There is 1 zinc atom on both sides and 2 hydrogen atoms on both sides. The equation is balanced.

Answer:

  1. $Zn+(2)HCl\rightarrow(1)ZnCl_2+(1)H_2$
