Identify the coefficients of the product CuO andNO2formed respectively when hydrated copper nitrate is themally decomposed.2Cu(NO_(3))_(2).6H_(2)OtoCuO+NO_(2)+6H_(2)O+O_(2)

Answer»

3 , 4
2 , 4
4 , 5
2 , 3

Solution :`2Cu(NO_(3))_(2)*6H_(2)Ooverset(Delta)to2CuO+4NO_(2)+O_(2)+6H_(2)O`
Coefficients of`CuOand NO_(2)`are respectively 2 and 4.
