Short On a scientific expedition across the ocean, your ship takes a sample of rock at locations A and E on the diagram and you compare the samples in the lab. Make a claim
about which rock is older and use evidence from the diagram to explain how you know which
of the two samples is older based on your knowledge of seafloor spreading. Use at least 3-4
complete sentences.

I don't see a diagram so I am just gonna guess

Explanation:

I believe that the sample at location (E) is older. This is because it would be more down stream so I was at location (A). Where as the rock at location (A) is newer because its more up stream.

no

explanation:

go away, people want answers, not to hook up

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.
