Answer 10

bitumen for roads and roofs

Question 11

properties of small hydrocarbon molecues

Answer 11

low boiling poinr, very volatile, flows easily, ignites easily

Question 12

properties of large hydrocarbon molecues

Answer 12

high boiling point, not very volatile, does not flow easily, does not ignite easily

Question 13

which is better fuel? small or large hydrocarbon

Answer 13

small because they are volitle, flow easily, and are easily ignited

Question 14

unique properties of carbon

Answer 14

each carbon can have up to 4 bonds, catenation, c-c bonds are stronger than elements in the same group thus greater stability in compounds containing c-c

Question 15

catenation

Answer 15

carbon atoms bond to each other & form long chain like structures
