For this question the answer is c
Because Na+ has less electrons than Na which means Na+ will be a smaller atom (give me brainliest please)
Answer:
5=C, every action has an equal or opposite reaction,
6=B, since it has less air drag and more force exerted on it
7= You're correct
Answer:
The molecular formula of an ascenapthalene is 
Explanation:


where,
=Elevation in boiling point = 
Mass of acenapthalene = 0.515 g
Mass of
= 15.0 g = 0.015 kg (1 kg = 1000 g)
= boiling point constant = 3.63 °C/m
m = molality
Now put all the given values in this formula, we get


Let the molecule formula of the Acenapthalene be ![C_{6n]H_{5n}](https://tex.z-dn.net/?f=C_%7B6n%5DH_%7B5n%7D)

n = 2.0
The molecular formula of an ascenapthalene is
