Question

Write balanced chemical equation for the following: (a) Burning of coal in a sufficient supply of air. CH4 +2O2 gives CO2 +2H2O+ heat+ light (b) Burning of coal in insufficient supply of air. 2CH4 +3O2 gives 2CO +4H2O+ heat+ light Name the type of reaction in both the cases and give reason why the second case is more dangerous

Answer 1

C+O2 gives CO2 sufficient supply of air

2C+O2 gives 2CO insufficient supply of air

complete combustion and incomplete combustion

second case is more dangerous becuase it produces highly toxic gas carbon monoxide.
