Question

$Zn+XHCl\to ZnC{l}_2+H_2$

In the above equation, the value of X is:

Answer 1

In a balanced chemical equation, the number of atoms on the reactant side is equals to the number of atoms on the product side,

so on balancing the equation we have,

$Zn+2HCl\to ZnC{l}_2+H_2$

so value of X = 2
