Balanced chemical equations for each of the following reactions: Aluminum nitrate → Aluminum oxide + Nitrogen dioxide + Oxygen

4Al(NO3)3 → 2Al2O3 + 12NO2 + 3O2

Balanced chemical equations for each of the following reactions: Nitrogen gas + Hydrogen gas → Ammonia gas

N2(g) + 3H2(g) → 2NH3(g)

Balanced chemical equations for each of the following reactions: Sodium metal + Water → Aqueous solution of sodium hydroxide + Hydrogen gas

2Na(s) + 2H2O(I) → 2NaOH(aq) + H2(g)

Balanced chemical equations for each of the following reactions: Solid copper(II) carbonate decomposes into solid copper(II) oxide and carbon dioxide gas when heated

CuCO3(s) → CuO(s) + CO2(g)

Balanced chemical equations for each of the following reactions: Burning of aluminium powder in excess oxygen produces white aluminium oxide powder

4Al(S) + 3O2(g) → 2Al2O3(S)

Balanced chemical equations for the following reactions: KI(aq) + Br2(aq) → I2(s) + KBr(aq)

2KI(aq) + Br2(aq) → I2(s) + 2KBr(aq)

Balanced chemical equations for the following reactions: Zn(s) + AgNO3(aq) → Zn(NO3)2(aq) + Ag(s)

Zn(s) + 2AgNO3(aq) → Zn(NO3)2(aq) + 2Ag(s)

Balanced chemical equations for the following reactions: C3H8(g) + O2(g) → CO2(g) + H2O(l)

C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(I)

Balanced chemical equations for the following reactions: AgNO3(s)→Ag(s) + NO2(g) + O2(g) Δ

2AgNO3(s) → 2Ag(s) + 2NO2(g) + O2(g) Δ
