Answer:
The resultant molarity is 0,7 M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
3,5 M x 20 ml= C2 x 100ml
C2= (3,5 M x 20 ml)/100ml
<em>C2= 0,7M</em>

It requires a force in the direction opposite to the motion of the object for it to slow down.
I think I have done a question like this before and i'm pretty sure your answer would be the 2nd one 1s22s22p4. I'm not 100% sure but try it at least.
The correct answer is A. Ammonia.
