xFeS2 + yO2 -> zFe2O3 + wSO2, what is the value of x + y + z + w?(a) 16(b) 21(c) 25(d) 32The question was asked in homework.The query is from Stoichiometry in section The Chemical Reaction Equation & Stoichometry, Material Balances for Processes Involving Reaction and Multiple Units of Basic Chemical Engineering

Answer»

Correct option is (c) 25

The best EXPLANATION: The balanced chemical reaction is 4FeS2 + 11O2 -> 2Fe2O3 + 8SO2, => X + y + z + w = 25.
