I am clueless on this question please help me !

The Answer is B, 18 smores.

Explanation:

It takes simple math. There are 36 graham crackers. You divide it by 2 because you have to use 2 crackers for each smore. There is more than enough marshmallows and squares of chocolate to make 18 smores.

You can only make 18 smores because even though there's a lot of marshmallows and square of chocolate, there is no more graham crackers to make more smores.

Hope this helped :)

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.
