Incomplete combustion gives

a. co2

b. carbon

c. water vapour

d. co

Answer 1

a) co2 is raised......

Answer 2

Since it's incomplete combustion, there won't be enough oxygen to produce CO2, and that's why carbon monoxide will be produced.

All a little bit of water vapor and carbot soot will be produced, but mostly carbon monoxide.

Hope it helped. ^^
