Question

what is the balanced equation for the complete combustion of each of the following: hexane, methylcyclohexane, cyclopentane and 2-dimethylpropane

Answer 1

Do you want to learn to do these or do you want someone to do your work. All of these are hydrocarbons. Adding oxygen and burning them produces CO2 and H2O for all.
All follow this routine:
CH4 + 2O2 ==> CO2 + 2H2O

Answer 2

I don't have a chemistry background, I was tring tolearn more, then to ask questions on things that I find difficult to do. Thanks for the idea, it helped me with the practice. I wasn't to give my work to somebody.
