Conservation of Mass

Balance the f...

Question

Balance the following equations:

$(e) . Z n + H C l \to Z n C l_{2} + H_{2}$

Open in App

Solution

The skeletal equation is:
$Z n + H C l \to Z n C l_{2} + H_{2}$

Count the number of atoms of each element on either side of the reaction

Number of atoms on reactant side:

$Z n = 1, H = 1, C l = 1$

Number of atoms on the product side:

$Z n = 1, H = 2, C l = 2$

To equalize $H$ and $C l$ , multiply $H C l$ by $2$ .

$Z n + 2 H C l \to Z n C l_{2} + H_{2}$

Therefore, the balanced chemical equation for the reaction is:
$Z n + 2 H C l \to Z n C l_{2} + H_{2}$
