Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()zn
Bingel [31]

Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.

Given chemical reaction is:

Zn + HCl → ZnCl₂ + H₂

Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:

Zn + 2HCl → ZnCl₂ + H₂

Hence we add 2 as a coefficient of HCl to balance the equation.
