C2H4 + xO2 -> 2CO2 + yH2O, what is the value of x + y?(a) 2(b) 3(c) 5(d) 8The question was posed to me during an online interview.This is a very interesting question from Stoichiometry in chapter The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Answer»

The correct option is (C) 5

The best explanation: The balance combustion EQUATION is C2H4 + 3O2 -> 2CO2 + 2H2O, => X = 3, y = 2, => x + y = 5.
