1.	Take copper nitrate in a test tube heat it over the flame. (i)What is the colour of cupric nitrate ? (ii)What do you observe ? (iii)Name the type of reaction that takes place. (iv)Write the balanced equation.
Answer» SOLUTION :(i)The COLOUR of cupric NITRATE is blue. (II)When cupric nitrate is heated in a test tube,we can observe the evolution of reddish brown GAS `(NO_(2))` Nitrogen di-oxide. (iii)The reaction takes place is decomposition reaction. `underset("Cupric nitrate")(2Cu(NO_(3))_(2))overset(Delta)tounderset("Cuprix oxide")(2CuO)+underset("Nitrogen di-oxide")(4NO_(2)uarr+O_(2)uarr)`
