Determine the ions of ammonium, in 870.4x10-23 grams of (NH4)3PO4. Round the results to the tenths.

it's c. elements are placed in rows based on how may valencies electrons have.

you gotta add the following molecules so we can give u an answer

explanation:

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.
