Question
The oxygen needed for complete combustion of 8 g CH4 may be obtained from complete decomposition of
Options
A.2/3 mole of KClO3
B.1 mole of H2O2
C.2 mole of NaNO3 (up to 300o C)
D.2 mole of BaO2
Solution
CH4 + 2O2 → CO2 + 2H2O
16 g 2 mole
∴8 g 1 mole
2KClO3 → 2KCl + 3O2
2H2O2 → 2H2O + O2
2NaNO3 → 2NaNO2 + O2
2BaO2 → 2BaO + O2
