Identify the ratio of the coefficients of the products `CuO,NO_(2) and H_(2)O` formed respectively when hydrated copper nitrate is thermally decomposed. `Cu(NO_(3))_(2).6H_(2)OtoNO_(2)+H_(2)O+O_(2)`A. `2 : 3 : 1`B. `1 : 2 : 3`C. `1 : 1.5 : 1`D. `3 : 2 : 1`

Answer» Correct Answer - 2
`2Cu(NO_(3))_(2).6H_(2)Oto2CuO+4NO_(2)+O_(2)+6H_(2)O`
Coefficients of CuO, `NO_(2) and H_(2)O` are respectively 2 , 4 and 6.
`:.` Ratio is `1 : 2 : 3`
