Question

Three Marks Question
1. Balance the following chemical equations :
(a) HNO3+ Ca(OH2), → Ca(NO3)2, + H2O

​

Answer 1

Answer:

2HNO3+ Ca(OH)2→ Ca(NO3)2+ 2H2O

Answer 2

Given Reaction:-

$HNO_3+ Ca(OH)_2 → Ca(NO_3)_2 + H_2O$

Balanced reaction :-

$4HNO_3+ 2Ca(OH)_2 → 2Ca(NO_3)_2 + 4H_2O$

Balanced reaction:- The reaction in which the total number of atoms in L.H.S or reactant is equal to R. H. S.or product side.

Step to balance the reaction :-

• First count the each atoms of each elements.

• Try to balance with elements having less number of atoms balance oxygen and hydrogen in last.

• If need multiply with suitable coefficients.

Note :- Reaction should be balanced so that they can follow law of conservation of mass.
