. Hydrogen peroxide is a volatile substance, it breaks down easily. The products of this decomposition reaction are
water and oxygen gas. The reaction starts with 50.0g of
hydrogen peroxide and produces 21.76 g of water. What is
the percent yield of this experiment?
2H,0, à 2H,0 +0,

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.
