    Q1. O2 (2Ag2O => 4Ag + O2)Q2. SO3 + H2O => H2SO4 (there is only one product, aka synthesis)Q3. SO2 + H2O => H2SO3Q4. Cu(OH)2 => H2O + CuO Q5.- They start with one reactant and end with more than one product.Q6. Mg(ClO3)2 => MgCl2 + 3O2Q7. Na2O + H2O => 2NaOHQ8. 3Ba + N2 => Ba3N2I want that hug!

    1) O22) SO3 + H2O3) SO2 + H2O4) Cu(OH)24) Cu(OH)25) They start with more reactive products etc.6) Mg(ClO3)2(s) + heat –> MgCl2(s) + 3O2(g)7) NaOH
