You are given 4.5 moles of O_2O2 to react with 1.60 x10^21.60x102 g C_2H_4C2H4. Upon completion of the reaction, will there be any remaining C_2H_4C2H4?
1 Answer
There is insufficient dioxygen to combust the ethylene completely.
Explanation:
We represent the combustion of ethylene by this reaction:
For complete combustion,
Here,
And, this quantity of ethylene requires,
However, we can certainly represent incomplete combustion:
And
Both of these reactions would occur to some extent in any combustion reaction. Given the limited quantity of oxidant, some ethylene would remain unreacted.
