Question

Осуществите превращения:Ca—»CaO—»Ca(OH)2Cu—»CuO—»CuSO4

Answer 1

Ответ:

2Ca + O₂ = 2CaO

CaO + H₂O = Ca(OH)₂

2Cu + O₂ = 2CuO

CuO + H₂SO₄ =CuSO₄ + H₂O

Answer 2

Ca → CaO → Ca(OH)₂:

1. Ca (calcium) reacts with oxygen (O₂) to form CaO (calcium oxide).
2. CaO reacts with water (H₂O) to form Ca(OH)₂ (calcium hydroxide).

Cu → CuO → CuSO₄:

1. Cu (copper) reacts with oxygen (O₂) to form CuO (copper oxide).
2. CuO reacts with sulfuric acid (H₂SO₄) to form CuSO₄ (copper sulfate).
