Answer:
The only balanced equation is:
2KClO₃ → 2KCl + 3O₂
Explanation:
In reactant side: 6 atoms of O, 2 atoms of Cl and 2 atoms of K
In product side: 2 atoms of K and 2 atoms of Cl + 6 atoms of O
CO + 3H₂ → CH₃OH
In reactant side: 1 C, 1 O and 6 H
In product side: 1 C, 4 H and 1 O
PCl₃ + 2Cl₂ → PCl₅
In reactant side: 1 P, 7 Cl
In product side. 1 P, 5 Cl
Mg + N₂ → Mg₃N₂
In reactant side 1 Mg and 2 N
In product side 3 Mg and 2 N
