. Balance the following chemical equations


(a) HNO3​+Ca(OH)2​→Ca(NO3​)2​+H2​O

(b) NaOH+H2​SO4​→Na2​SO4​+H2​O

(c) NaCl+AgNO3​→AgCl+NaNO3​

(d) BaCl2​+H2​SO4​→BaSO4​+HCl

Best Answer

Ans. (a) 2HNO3​+Ca(OH)2​→Ca(NO3​)2​+2H2​O

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+H2​SO4​→Na2​SO4​+2H2​O

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​+H2​SO4​→BaSO4​+2HCl

This is a double displacement response since there's an exchange of ions between the reactants, forming new products.
