Question

1) nitric acid reacts with calcium hydroxide and forms calcium nitrate and water .
2) sodium bicarbonate decomposes to give sodium carbonate , carbon die oxide and water .
3) sodium chloride reacts with water to give aluminium sulphate and hydrogen gas .
4 )aluminium metals reacts with sulphuric acid to give aluminiun sulphate and hydrogen gas .
5 ) phosphorus pentoxide reacts with water to give phosphoric acid .

Answer 1

Hey frnd .....

1) Nitric acid reacts with calcium hydroxide and forms calcium nitrate and water.
2HNO3 + Ca(OH)2 → Ca(NO3)2 + 2H2O


2) Sodium bicarbonate decomposes to give sodium carbonate, carbon di oxide and water.
2NaHCO3 → Na2CO3 + CO2 + H2O



3) Sodium chloride reacts with water to give aluminium sulphate and hydrogen gas.
Given reaction is wrong (not possible). Actual reaction will be
NaCl + H2O → NaOH + HCl (these products are unstable and reaction proceeds towards otherside)



4) Aluminum metals reacts with Sulphuric acid to give Aluminium sulphate and hydrogen gas.
2Al + 3H2SO4 → Al2(SO4)3 + 3H2


5 ) Phosphorus pentoxide reacts with water to give phosphoric acid.
P2O5 + 3H2O → 2H3PO4

Answer 2

Answer:

1) Nitric acid reacts with calcium hydroxide and forms calcium nitrate and water.

2HNO3 + Ca(OH)2 → Ca(NO3)2 + 2H2O

2) Sodium bicarbonate decomposes to give sodium carbonate, carbon di oxide and water.

2NaHCO3 → Na2CO3 + CO2 + H2O

3) Sodium chloride reacts with water to give aluminium sulphate and hydrogen gas.

Given reaction is wrong (not possible). Actual reaction will be

NaCl + H2O → NaOH + HCl (these products are unstable and reaction proceeds towards otherside)

4) Aluminum metals reacts with Sulphuric acid to give Aluminium sulphate and hydrogen gas.

2Al + 3H2SO4 → Al2(SO4)3 + 3H2

5 ) Phosphorus pentoxide reacts with water to give phosphoric acid.

P2O5 + 3H2O → 2H3PO4
