reactions

Question 1

describe hydrocarbon reactions with oxygen (consider reaction type, products, endo/exothermic, uses of this reaction, types)

Answer 1

• combustion (react with oxygen to get CO2 and water vapour)
• exothermic
• release energy and create fuel
• two types: complete and incomplete combustion

Question 2

what hydrocarbon reaction has excess oxygen?

Answer 2

complete combustion

Question 3

what hydrocarbon reaction has a blue flame?

Answer 3

complete combustion

Question 4

what hydrocarbon reaction has limited amount of oxygen?

Answer 4

incomplete combustion

Question 5

what hydrocarbon reaction has a yellow/orange flame?

Answer 5

incomplete combustion

Question 6

main products of complete combustion

Answer 6

CO2 gas and water gas

(never fully a complete combustion, always have some CO and C produced as well)

Question 7

is it easy to start a complete combustion reaction?

Answer 7

no, requires high activation energy even though its exothermic, because only once it is started can the reaction be self-sustaining.

Question 8

main products of incomplete combustion

Answer 8

carbon monoxide gas and carbon solid

(never a fully incomplete combustion, always have some CO2 produced as well)
