Answer
2NaCl + Cal₂ → 2Nal + CaCI₂
Explanation
Given unbalanced equation;
NaCl + _Cal₂ → Nal + CaCI₂
Step 1: Balance the Cl atom on both the reactant and product sides of the equation by putting 2 as the coefficient of NaCl in the reactant side.
2NaCl + _Cal₂ → Nal + CaCI₂
Step 2: Balance the Na atom on both the reactant and product sides of the equation by putting 2 as the coefficient of NaI in the product side.
2NaCl + Cal₂ → 2Nal + CaCI₂
Therefore, the balanced equation is: 2NaCl + Cal₂ → 2Nal + CaCI₂
