Reflect on the claims and the evidence you examined today. At this point, which claim do you think is best supported by the evidence? Claim 1: There is frozen water in tank 2, which is blocking some of the oxygen from going into tank 3.

Claim 2: Some of the liquid oxygen evaporated in tank 3.

Claim 3:, Some of the oxygen didn’t condense in tank 2.

give me abc and i will get it for u.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
