Question

Используя выданные реактивы,осуществите практически последовательное превращение веществ:а)оксид кальция-гидроксид кальция-сольб)оксид фосфора 5-фосфорная кислота-сольнапишите уравнения реакций дайте название солей

Answer 1

a) cao+h2o=ca(oh)2

ca(oh)2+2hcl=cacl2+2h2o

б) p2o5+h2o=h3po4

h3po4+3naoh=na3po4+3h2o

Answer 2

Conversion of Calcium Oxide to Calcium Hydroxide to Salt

To convert calcium oxide (CaO) to calcium hydroxide (Ca(OH)2), we can use water (H2O) to react with calcium oxide. This reaction is known as the hydration of calcium oxide.

The balanced chemical equation for the reaction is:

CaO + H2O → Ca(OH)2

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

The name of the salt formed in this reaction is calcium hydroxide.

Conversion of Phosphorus Pentoxide to Phosphoric Acid to Salt

To convert phosphorus pentoxide (P2O5) to phosphoric acid (H3PO4), we can use water (H2O) to react with phosphorus pentoxide. This reaction is known as the hydration of phosphorus pentoxide.

The balanced chemical equation for the reaction is:

P2O5 + 3H2O → 2H3PO4

Phosphorus pentoxide (P2O5) reacts with water (H2O) to form phosphoric acid (H3PO4).

The name of the salt formed in this reaction is phosphoric acid.

Please note that the names of the salts formed in these reactions are calcium hydroxide and phosphoric acid, respectively.
