need help showing my work and balancing these equations, thank you!

A+BAB In decomposition, one reactant decomposes into two or more compounds. ABA+B State whether the reactions below are synthesis or decomposition reactions THEN BALANCE THE EQUATION AND SHOW YOUR WORK. Some reactions may already be balanced. Ca+O2CaOBaCO3BaO+CO2 Reaction Type: Fe(OH)2FeO+H2O KClO3KCl+O2 SO2+H2OH2SO3 H2+Cl2+HCl Reaction Type: NaClO3NaCl+O2 Reaction Type: Li2O+H2OLiOH Reaction Type: Al+Br2AlBr3 Reaction Type: Zn(OH)2ZnO+H2O CuSO4CuO+SO3 Ag+S8Ag2S Reaction Type: Reaction Type: Reaction Type
