Synthesis/decomposition reactions + key terms

Synthesis - oxy acids formation

non-metal oxide reacts with water produces an oxy acid

Ex; N2O5(g) + H2O(L) = NO3(aq)

Synthesis - base formation

Metal oxide + water, produce metal-hydroxide

Synthesis ex; CaO(s) + H2O(L) = Ca(OH)2 (aq)

Decompostion ex; Mg(OH)2 = Mg2O(s) + H2O(L)

Chlorate (ClO3-) —> ?

becomes —> Cl2 + O2

Ex with a metal chlorate;

Metal chlorate yields metal chloride + oxygen gas

• NaClO3 —→ NaCl(s) + O2(g)

Nitrate (NO3-) —> ?

becomes metal oxide(s) + NO2(g) + O2(g)

Carbonate (CO3)2 —> ?

becomes CO2(g)+ O2(g)

Ex with metal carbonate;

Metal carbonate yields metal oxide + carbon dioxide gas

• Li2CO3(s) = Li2O(s) + CO2(g)
