Which type of fossil fuel is made from trees, ferns, mosses, and other marsh plants?

petroleum

crude oil

coal

natural gas

i would say b

explanation:

but i think i would need more information than that

fe 55.85 g/mol and h2o 18.02 g/mol.

im pretty sure its b

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.
