Question

@ 4. Balance the equation-
i HNO3 + Ca(OH)2 Ca(NO3)₂ + H₂O
(ii) BAcl2+H2SO4 =BASo4 +HCl​

Answer 1

Answer:

@ 4. Balance the equation-

i HNO3 + Ca(OH)2 Ca(NO3)₂ + H₂O

(ii) BAcl2+H2SO4 =BASo4 +HCl

Answer 2

SOLUTION :

I) HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + H₂O

2HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + 2H₂O

ii) BaCl₂ + H₂SO₄ → BaSo₄ + HCl

BaCl₂ + H₂SO₄ → BaSo₄ + 2HCl

EXPLANATION :

• Count atoms of reactant in LHS and product RHS.

• Accordingly, use coefficient to balance it

• Don't make any change in subscript of formula

NOTE : Add coefficient in front of formula.
