  When Iron nail (Ferrum) is dipped in Copper sulphate (CuSO4) there takesreaction between them and coppersulphate change its color from blue to light green. ... 2) colour of the solution turns from blue to light green. The formula for this reaction is: Fe + CuSO4 --> FeSO4 + Cu. Here, Fe is more reactive than Cu.

 In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases heat. If carried out in atmospheric airinstead of pure oxygen (as is usually the case), hydrogen combustion may yield small amounts of nitrogen oxides, along with the water vapor.
