Question

P+HNO3->Cu(No3)2+H2O
ZnO+HCI->Q+H2O
R+H2SO4->MgSO4+S+H2o

Identify the P,Q,R and S
​

Answer 1

Answer:

P= CuO

Q= $ZnCl_{2}$

R= Mg

Explanation:

1. CuO + 2HNO3- -------> Cu(NO3)2 + H2O

The above chemical reaction is a neutralization reaction in which CuO is the base and HNO3- is an acid. Acid reacts with base to form salt and water.

2. ZnO + 2HCl --------->  $ZnCl_{2}$ + H2O

The above reaction is neutralization reaction in which the base is ZnO and HCl is an acid. Acid reacts with base to form salt and water.

3. 3Mg + 4H2SO4 --------> 3MgSO4 + S + 4H2O

The above chemical reaction is the balanced chemical reaction in which Mg metal reacts with acid to form salt, sulphur and water.
