A dilute acid solution is prepared by adding the concentrated acid to water. If you do the reverse, i.e. add water to the acid it is possible that a small amount water could react with acid and boil and explode thus splashing the acid onto you or someone else near the activity.
it’s previous models because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter

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.
