1.	Study the following conversion schemes:For each of the conversion in the scheme given below, state briefly in words or by means of chemical equation, how the conversion is carried out ?
Answer» [A] Copper (II) oxide, when heated with coke powder is reduced to metallic copper. CuO + C → Cu(Metallic copper) + CO [B] Copper (II) oxide is dissolved in dilute sulphuric acid to form copper sulphate. CuO + H₂SO₄ → CuSO₄(Copper sulphate) + H₂O [C] Copper sulphate is dissolved in water and hydrogen suiphide gas is passed, a black precipitate of copper suiphide is formed. CuSO₄ + H₂S → CuS(Black ppt.) + H₂SO₄ [D] Copper (II) oxide is dissolved in dilute hydrochloric acid to form copper chloride. To the solution of copper chloride, when a saturated solution of sodium carbonate is added, a light blue precipitate of copper (II) carbonate is formed. CuCl₂ + Na₂CO₃ → CuCO₃ + 2NaCl

Answer»

[A] Copper (II) oxide, when heated with coke powder is reduced to metallic copper.

CuO + C → Cu(Metallic copper) + CO

[B] Copper (II) oxide is dissolved in dilute sulphuric acid to form copper sulphate.

CuO + H₂SO₄ → CuSO₄(Copper sulphate) + H₂O

[C] Copper sulphate is dissolved in water and hydrogen suiphide gas is passed, a black precipitate of copper suiphide is formed.

CuSO₄ + H₂S → CuS(Black ppt.) + H₂SO₄

[D] Copper (II) oxide is dissolved in dilute hydrochloric acid to form copper chloride. To the solution of copper chloride, when a saturated solution of sodium carbonate is added, a light blue precipitate of copper (II) carbonate is formed.

CuCl₂ + Na₂CO₃ → CuCO₃ + 2NaCl
