question 9 in the excel book (new one) in POM:
after ethylene was reacted with a certain chemical it was
oxidised. The oxidised product turned litmus red. Identify the chemical that reacted with ethylene.
The answer is H2O but if someone could explain to me how to get this answer that would be great
sorry but, are u sure that it is oxidized not combusted, or reacted to oxygen or something else. (lol being a little too optimistic)
oxidized seems a little vague for this question. if it reacted with oxygen, then i would be able to tell u the answer.
oh well, i will just assume that oxidized means, reacting with oxygen.
C2H4 + 302 ---> 2CO2 + 2H2O (complete combustion)
any hydrocarbon that undergoes complete combustion produces CO2 and water. CO2 and water are the products of this equation, it will form an equilibrium
CO2 + H2O <---> H2CO3
CO2 and water react together to form an acidic substance, which in turn will make litmus blue turn red.
what happens is that CO2 dissolves in water, which in turn allows the pH to decrease, making the water slightly acidic. it is a common misconception that rain water is neutral, but actually the CO2 in the atmosphere, dissolves in those rain droplets, making them slightly acidic.
hopefully this right. if that oxidised meant reacted with oxygen, then i am pretty sure i am right, if not then ...... i dunno.
hope it helps.
