The formula unit cso, als, rbi, or becl is neutral

RbI

Explanation:

Let is carefully look at the charges on each option.

Rb is in group one of the periodic table, therefore it has a charge of +1. Iodine is in group seventeen of the periodic table hence it has a charge of -1. The two charges cancel out thereby leaving a neutral formula unit. That is RbI has a net charge of 1+(-1)=0. RbI is neutral.

None of the other options or remaining choices end up being neutral. Therefore the correct answer is RbI.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
