2) If cobalt(II) sulfate is heated too strongly, the following reaction will occur CoSO4(s) → COO(s) + SO3(g)
If you are heating a sample of CoSO: 6H30 and this reaction occurs along with
dehydration, what will happen to the experimental percent water? Explain your
answer.

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.
