1.133 g of silver nitrate was heated in an open tube. The silver residue weighed 0.720 g. During the reaction 0.307 g of nitrogen dioxide was also produced. The rest of the mass loss was due to oxygen. Use the data to write the equation for the reaction.

Answer :

[tex]AgNO_3--^T-->Ag_2O+NO_2\uparrow+O_2\uparrow\\\\ N^{+V}+1e\rightarrow N^{+IV}|4\\ 2O^{-II}-4e\rightarrow O_2^0|1\\\\ 4AgNO_3--^T-->2Ag_2O+4NO_2\uparrow + O_2\uparrow[/tex]
