Zinc oxide reacts with water to form zinc hydroxide. If 0.25 mol of zinc oxide is reacted with 0.25 molof water to produce 0.19 mol of zinc hydroxide, what is the percent yield of this reactio

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.

you need to have a picture of the atom that way we can answer it

idk what is it? is this a question that you know the answer or u dont
