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 since each $HCl$ has 1 chlorine atom. So far, the equation is $Zn + 2HCl\rightarrow ZnCl_2+H_2$.

Step2: Check other elements

The zinc atom is already balanced (1 zinc atom on both sides), and with the coefficient of 2 for $HCl$, the hydrogen atoms are also balanced (2 hydrogen atoms on both sides).

Answer:

  1. $Zn + 2HCl\rightarrow1. ZnCl_2+1. H_2$ (The coefficients are 1, 2, 1, 1 respectively)
