Copper Carbonate

Copper I Carbonate → Copper Oxide + Carbon Dioxide
Cu₂CO₃ → CuO + CO₂
(unbalanced)


Copper II Carbonate → Copper Oxide + Carbon Dioxide
CuCO₃ → CuO + CO₂
123.6 g of CuCO₃ → 79.6 g of CuO + 44 g of CO₂


Copper II Carbonate + Sulfuric acid → Copper Sulfate + Water + Carbon Dioxide
CuCO₃ + H₂SO₄ → CuSO₄ + H₂O + CO₂
123.6 g of CuCO₃ + 98 g of H₂SO₄ → 159.6 g of CuCO₃ + 18 g of H₂O + 44 g of CO₂

check: 123.6 g+ 98 g = 159.6 + 18 + 44

H₂SO₄ = 2+32+64 = 98 g/mol
CuSO₄ = 63.6+32+64 = 159.6 g/mol
CuCO₃ = 123.6 g g/mol
Water = 18 g/mol
CO₂ = 44 g/mol
