Question 5 If 0.664 g of an acid was required to neutralize 10.0 mL of 0.800 M NaOH,
calculate the Molar Mass of
the acid given it reacts with sodium hydroxide in a 1:2 istio. e., 1 ACID : 2 NaOH. (3)

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.
