Question

please balance the equations ​

Answer 1

Answer:

3 $P_{4}$ + 20 $HNO_{3}$ + 8 $H_{2}$O → 12 $H_{\\3}$$PO_{4}$+ 20 NO

2NaOH + $Cl_{2}$ ---> NaClO + NaCl + $H_{2}$O

Answer 2

The balanced form of the given chemical equations are as follows :

(i) 3P4 + 20HNO3 + 8H2O 12H3PO4 + 20NO

(ii) Cl2 + 2NaOH NaCl + NaOCl + H2O

• An equation is called balanced if the number of atoms of a particular element present on the reactant side is equal to the number of atoms of the same element present on the product side.

• A chemical equation is balanced by a

trial and error method. The atoms on the sides of both reactants and products are multiplied by the lowest possible natural numbers in order to equalise their numbers.

Kindly refer to the image attached below to understand how the above two equations are balanced.
