Question

An amount of 2 moles of KClO3 is decomposed completely to produce O2 gas. How many moles of butene C4H8 can be burnt completely by the O2 gas produced?

Options

A.0.5
B.1.0
C.2.0
D.3.0

Solution

2KClO3 → 2KCl + 3O2

C4H8 + 6O2 → 4CO2 + 4H2O

2 mole of KClO3 ≡ 3 mole of O2 ≡ 0.5 mole of C4H8
