Question

Помогите пожалуйста:Co2+Zn(OH)2=?Co2+Al(OH)3=?ZnO+HCl=?H2SO4+Na2O=?

Answer 1

2Zn(OH)2 + CO2 = Zn2CO3(OH)2↓ + H2O
CO2+Al(OH)3 ≠ реакция не идет
ZnO + 2HCl = ZnCl2 + H2O
H2SO4 + Na2O = Na2SO4 + H2O

Answer 2

Co2 + Zn(OH)2

The reaction between carbon dioxide (Co2) and zinc hydroxide (Zn(OH)2) can be represented as follows:

Co2 + Zn(OH)2 → ZnCO3 + H2O [[3]](https://publications.hse.ru/pubs/share/direct/249069387.pdf).

The reaction produces zinc carbonate (ZnCO3) and water (H2O).

Co2 + Al(OH)3

The reaction between carbon dioxide (Co2) and aluminum hydroxide (Al(OH)3) can be represented as follows:

Co2 + Al(OH)3 → Al2(CO3)3 + H2O [[3]](https://publications.hse.ru/pubs/share/direct/249069387.pdf).

The reaction produces aluminum carbonate (Al2(CO3)3) and water (H2O).

ZnO + HCl

The reaction between zinc oxide (ZnO) and hydrochloric acid (HCl) can be represented as follows:

ZnO + 2HCl → ZnCl2 + H2O.

The reaction produces zinc chloride (ZnCl2) and water (H2O).

H2SO4 + Na2O

The reaction between sulfuric acid (H2SO4) and sodium oxide (Na2O) can be represented as follows:

H2SO4 + Na2O → Na2SO4 + H2O.

The reaction produces sodium sulfate (Na2SO4) and water (H2O).
