Answer 1

Ответ:

1.

a) CuO, K₂O, PbO, BaO

b) AI(OH)₃, Mg(OH)₂

c) H₂SiO₃, H₂SO₄

d) Fe(OH)₂CI, CuOHCI

2.

a) 2KOH+H₂SO₄=K₂SO₄+2H₂O

b) 3NaOH+H₃PO₄=Na₃PO₄+3H₂O

3.

a) CuO+2HCI=CuCI₂+H₂O

b) Cu(OH)₂+2HCI=CuCI₂+2H₂O

4. Mg→MgSO₄→Mg(OH)₂→MgO→MgCI₂

Mg+H₂SO₄=MgSO₄+H₂

MgSO₄+2NaOH=Mg(OH)₂+Na₂SO₄

Mg(OH)₂+t°C=MgO+H₂O

MgO+2HCI=MgCI₂+H₂O

5.

a) K₂SiO₃

b) Zn₃(PO₄)₂
