Question

How many moles of oxygen are required to burn in one mole of C4H8 completely?

Answer 1

Answer:

6 moles of oxygen is required to burn 1 mole of C4H8 completely

Explanation:

reaction is C4H8 + (6)O2 ------ (4)CO2+ (4)H2O

Answer 2

you get CO2 and H2O whenever you burn hydro carbons. so C4H8 + O2 = CO2 + H2O. Then, you must balance the equation: C4H8 + 6O2 = 4CO2 + 4H2O

burning 1 mol of butene gets you 6 mol of O2
