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.
`2Cu(NO_(3))_(2).6H_(2)OtoNO_(2)+H_(2)O+O_(2)+2CuO`

Options

A. 2:3:1
B. 1:2:3
C. 1:1.5:1
D. 3:2:1

Answer

b

Explanation

`2Cu(NO_3)_2 . 6H_2O to 2CuO + 4NO_2 + O_2 + 6H_2O`
Coefficients of CuO, `NO_2` and `H_2O` are respectively 2, 4 and 6.
`:.` Ratio is 1:2:3
