Answer 1

Ответ:

Объяснение:

а) Fe(ОН)3  3) Fe2О3

б) Н2СO3    1) CО2

в) Н3РO4     2) Р2О5

Answer 2

1) Fe(OH)3 (Iron(III) hydroxide) - 3) Fe2O3 (Iron(III) oxide) 2) H2CO3 (Carbonic acid) - 1) CO2 (Carbon dioxide) 3) H3PO4 (Phosphoric acid) - 2) P2O5 (Phosphorus pentoxide)

Explanation:

Fe(OH)3 (Iron(III) hydroxide) is a base, while Fe2O3 (Iron(III) oxide) is an oxide.

H2CO3 (Carbonic acid) is an acid, while CO2 (Carbon dioxide) is an oxide.

H3PO4 (Phosphoric acid) is an acid, while P2O5 (Phosphorus pentoxide) is an oxide.

When an acid reacts with an oxide, a salt and water are typically formed. In these cases, the acids (H2CO3 and H3PO4) are reacting with the respective oxides (CO2 and P2O5) to form salts.
