The percent yield of a reaction in 2 points which 52 grams of a reactant is expected to yield 30 grams of product is 25%. What is the actual yield of the reaction? 208 grams 120 grams O 13 grams 7.5 grams

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

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.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

it is reliable if two scientists recorded it
