Balance the following chemical equations

Remember that chemical reactions are also chemical changes. In a chemical equation you can see how reactants change AND other products are formed. Classify the following chemical reactions as: synthesis or combination reaction, decomposition reaction, substitution or single displacement reaction, substitution or double displacement reaction. 2 NaI + Br2 → 2 NaBr + I2 2 HCl + Zn → Cl2Zn + H2 KCl + AgNO3 → KNO3 + AgCl K2S + MgSO4 → K2SO4 + MgS Na2O (s) + H2O (l) → 2Na (OH) (aq) SO3 (g) + H2O (l) → H2SO (aq) HCl + NaOH → NaCl + H2O
