Balancing Equations

Question

Balance the equation. Then add up the coefficients on both sides of this properly balanced equation and identify the total

~

N₂ + H₂ → NH₃

_~

KNO₃ + H₂CO₃ → K₂CO₃ + HNO₃

_~

Na₃PO₄ + HCl → NaCl + H₃PO₄

_~

KClO₃ + P₄ → P₄O₁₀ + KCl

~

Hg(OH)₂ + H₃PO₄ → Hg₃(PO₄)₂ + H₂O

~

Fe + HC₂H₃O₂ → Fe(C₂H₃O₂)₃ + H₂

Answer 1

Na₃PO₄ + 3HCl → 3NaCl + H₃PO₄

_~

10KClO₃ + 3P₄ → 3P₄O₁₀ + 10KCl

~

3Hg(OH)₂ + 2H₃PO₄ → Hg₃(PO₄)₂ + 6H₂O

~

Fe + 2HC₂H₃O₂ → Fe(C₂H₃O₂)₃ + H₂

Answer 2

You always want to make sure you are counting the subscript. So have 3 H2 is the same thing as 2 H3.

N₂ + 3 H₂ → 2NH₃

2KNO₃ + H₂CO₃ → K₂CO₃ + 2HNO₃
