Question

Give balanced equation for the action of heat on :

Silver nitrate

Answer 1

When silver nitrate is heated it gives Silver, oxygen, and nitrogen dioxide.

This can be represented by the equation-

${\mathrm{AgNO}}_3\left(\mathrm{l}\right)\to \mathrm{Ag}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)+{\mathrm{NO}}_2\left(\mathrm{g}\right)$

We get an unequal number of atoms on the reactant and product side.

Atoms	Reactant	Product
Ag	1	1
N	1	1
O	3	4

Balancing the equation-

• We multiply the Silver nitrate molecule by 2.
• We get extra silver and nitrogen atoms, we multiply silver and nitrogen dioxide in the product by 2.

Atoms	Reactant	Product
Ag	2	2
N	2	2
O	6	6

Hence, the balanced equation is-

$\underset{\mathrm{Silver}\mathrm{nitrate}}{2{\mathrm{AgNO}}_3\left(\mathrm{s}\right)}\to \underset{\mathrm{Silver}}{2\mathrm{Ag}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Nitrogen}\mathrm{dioxide}}{2{\mathrm{NO}}_2\left(\mathrm{g}\right)}$
