Equation
Balance the chemical equation
2H2 + O2 → 2H2O
2H + O → 2H2O
H + O→ 2H2O
It is already balanced
Balance the chemical equation
4Na + O2 → 2Na2O
3Na + 2O2 → 2NaO
Na + 4O2 → 8Na2O
It is already balance
Balance the chemical equation.
C + 2H2 → CH4
5C + H2 + O2 → CH4
3C + 2H2 → CH4
It is already balanced
Balance the chemical equation
2Al2O3 → 4Al + 3O2
Al2O3 → 4Al + 3O2
8Al2O3 → Al + O2
It is already balanced.
Balance the chemical equation.
N2 + 3H2 → 2NH3
8N2 + 6H2 → 2NH3
N2 + H2 → 2NH3
It is already balanced.
