| Arrange the coefficients: Ba + O2 → BaO Na + S → Na2S Fe + O2 → Fe3O4 C + O2 → CO2 CH4 → C2H2 + H2 Ca + HCl → CaCl2 + H2 K + S → K2S Fe + Cl2 → FeCl3
2Ba + O2 → 2BaO (compound reaction).
2Na + S → Na2S (compound reaction).
3Fe + 2O2 → Fe3O4 (compound reaction).
C + O2 → CO2 (compound reaction).
2CH4 → C2H2 + 3H2 ↑ (decomposition reaction).
Ca + 2HCl → CaCl2 + H2 ↑ (substitution reaction).
2K + S → K2S (compound reaction).
2Fe + 3Cl2 → 2FeCl3 (compound reaction).
