Answer

Explanation:

Step1: Balance chlorine atoms

On the right - hand side, in $ZnCl_2$, there are 2 chlorine atoms. In $HCl$ on the left - hand side, to balance the chlorine atoms, the coefficient of $HCl$ should be 2. $Zn + 2HCl\rightarrow ZnCl_2+H_2$

Step2: Check other atoms

For zinc ($Zn$), there is 1 zinc atom on both sides, and for hydrogen ($H$), there are 2 hydrogen atoms on both sides. So the balanced equation is $Zn + 2HCl\rightarrow ZnCl_2+H_2$.

Answer:

  1. $Zn$ coefficient: 1
  2. $HCl$ coefficient: 2
  3. $ZnCl_2$ coefficient: 1
  4. $H_2$ coefficient: 1
