CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O 10.0 g of calcium carbonate reacts with 150 cm³ of hydrochloric acid of concentration 4.0 g/dm³. Calculate the volume of carbon dioxide produced at RTP.

Calcium carbonate decomposes according to the equation: CaCO₃ → CaO + CO₂ 12.5 g of calcium carbonate produces 5.0 g of calcium oxide. Calculate the percentage yield of calcium oxide.

Mg + 2HCl → MgCl₂ + H₂ 5.0 g of magnesium reacts with 20.0 g of hydrochloric acid. Calculate the maximum mass of magnesium chloride that can be produced.

Copper is produced from copper(II) oxide using carbon: 2CuO + C → 2Cu + CO₂ 20.0 g of copper(II) oxide reacts and produces 12.0 g of copper. Calculate the percentage yield of copper.
