Answer 1

Answer :-

Balanced reaction :- The reaction in which the total number of atoms on the reactant side is equal to the total number of atom on the product side.

Given reaction:-

$HNO_3+Ca(OH)_2→Ca(NO3)_2+H_2O$

Balanced reaction:-

$2HNO_3+Ca(OH)_2→Ca(NO3)_2+2H_2O$

Given reaction:-

$NaOH+H_2SO_4→Na_2SO_4+H_2O$

Balanced reaction:-

$2NaOH+H_2SO_4→Na_2SO_4+2H_2O$

Given reaction:-

$NaCI_2+AgNO_3→AgCI+NaNO_3$

Balanced reaction:-

$2NaCI_2+2AgNO_3→2AgCI+2NaNO_3$

Given reaction:-

$BaCI_2+H_2SO_4→BaSO_4↓+HCI$

Balanced reaction:-

$2BaCI_2+2H_2SO_4→2BaSO_4↓+4HCI$
