3.
а) Ca + H₂SO₄ = CaSO₄ + H₂↑
б) 2AgNO₃ + t = 2Ag↓ + 2NO₂↑ +O₂↑
4. CuSO₄→Cu→CuCI₂→Cu(OH)₂→CuO→Cu(NO₃)₂→Cu→CuO→CuSO₄→BaSO₄
CuSO₄ + Fe = Cu + FeSO₄
Cu + 2AgCI=CuCI₂ + 2Ag
CuCI₂ + 2NaOH= Cu(OH)₂↓ +2NaCI
Cu(OH)₂ + t = CuO + H₂O
CuO + 2HNO₃ = Cu(NO₃)₂ + H₂O
Cu(NO₃)₂ + Zn = Cu + Zn(NO₃)₂
2Cu + O₂= 2CuO
CuO + H
₂SO₄=
CuSO₄ + H
₂O
CuSO₄ + BaCI₂ = CuCI₂ + BaSO₄↓
