HI

Following one three sets of chemical reactions. Decide if any of them can be replaced by a smaller equivalent set of reactions. 2C2H4 + O2 = 2C2H4O C2H4 + 3O2 = 2CO2 + 2H2O 2c2H4O + 5O2 = 4CO2 + 4H2O 4NH3 + 5O2 = 4NO + 6H2O 4NH3 + 3O2 = 2N2 + 6H2O 4NH3 + 6NO = 5N2 + 6H2O 2NO + O2 = 2N)2 2NO = N2 + O2 2NO= N2 + O2 N2 + 2O2 = 2NO2 2NaCI + H2SO4 = Na2SO4 + 2HCI Na2SO4 + 4C = Na2S + 4CO Na2S + CaCO3 = Na2CO3 + CaS

Solution

1. adding,3C2H4+9O2--> 6CO2+6H2O,C2H4+3O2---> 2CO2+2H2O
