. Balance the following chemical equations
(a) HNO3+Ca(OH)2→Ca(NO3)2+H2O
(b) NaOH+H2SO4→Na2SO4+H2O
(c) NaCl+AgNO3→AgCl+NaNO3
(d) BaCl2+H2SO4→BaSO4+HCl
Best Answer
Ans. (a) 2HNO3+Ca(OH)2→Ca(NO3)2+2H2O
It is a double displacement reaction since both molecules of the reactions are displaced to form new products.
Nitric acid (HNO3) combines with calcium hydroxide [Ca(OH)2] to produce calcium nitrate[Ca(NO3)2]-a salt and water, which is a neutralization reaction.
Hence, this reaction is both a double displacement as well as a neutralization reaction.
(b) 2NaOH+H2SO4→Na2SO4+2H2O
It's a double displacement reaction since both molecules of the reactions are displaced to form new products.
It's a double relegation reaction since both atoms of the reactions are displaced to form new products.
Sulphuric acid (H2SO4) combines with sodium hydroxide (NaOH) to produce sodium sulphate (Na2SO4)-a swab and water, which is a neutralization response.
Hence, this response is both a expulsion as well as a neutralization reaction.
(c) NaCl+AgNO3→AgCl+NaNO3
This is a double relegation response since there's an exchange of ions between the reactants, forming new products
(d) BaCl2+H2SO4→BaSO4+2HCl
This is a double displacement response since there's an exchange of ions between the reactants, forming new products.
