1)P+O2=2)MgO+HCI=3)N2O5+H2O4)CaO+CO2=5)KOH+SO2=6)Cu(OH)2=7)CuS+O2=​

Answer 1

Объяснение:

1)4P+5O2=2P2O5

2)MgO+2HCI=MgCl2 + H2O

3)N2O5+H2O= 2HNO3

4)CaO+CO2=CaCO3

5)KOH+SO2=KHSO3

6)Cu(OH)2=CuO+H2O

7)2 CuS + 3 O2=2 CuO + 2 SO2

Answer 2

1) P + O2

The reaction between phosphorus (P) and oxygen (O2) results in the formation of phosphorus pentoxide (P2O5).

2) MgO + HCl

The reaction between magnesium oxide (MgO) and hydrochloric acid (HCl) produces magnesium chloride (MgCl2) and water (H2O).

3) N2O5 + H2O

When nitrogen pentoxide (N2O5) reacts with water (H2O), it forms nitric acid (HNO3).

4) CaO + CO2

Calcium oxide (CaO) reacts with carbon dioxide (CO2) to produce calcium carbonate (CaCO3).

5) KOH + SO2

The reaction between potassium hydroxide (KOH) and sulfur dioxide (SO2) results in the formation of potassium sulfite (K2SO3).

6) Cu(OH)2

Copper hydroxide (Cu(OH)2) is a compound that consists of copper (Cu) and hydroxide (OH) ions.

7) CuS + O2

When copper sulfide (CuS) reacts with oxygen (O2), it forms copper oxide (CuO).
