Answer:

  • Mg + 2HCl ⇒ MgCl₂ + H₂
  • Coefficient of HCl = 2

Explanation:

Equation (given) :

  • Mg + HCl ⇒ MgCl₂ + H₂

Compare the LHS and RHS :

  • On the left side, there are only single atoms of H and Cl, whereas there are 2 of each on the right side
  • As HCl is a single compound on the left, multiply HCl into 2 to balance the reaction
  • Coefficient of HCl = 2

Balanced Equation :

  • Mg + 2HCl ⇒ MgCl₂ + H₂
