For diffusion, it could be: particles have inter- particle spaces between them, particles of matter attract each other, which is the strongest in the case of a solid, little less in liquids, and least in gases, and states of matter that are packed tightly together diffuse slowly.
For Brownian motion, it could be: particles have spaces between them, particles are incredibly small, and that particles are always, continuously moving.
Hope this helps!
Answer:
Helium
Explanation:
Atomic radii vary in a predictable manner across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group and decreases from left to right over a period of time. Helium is therefore the smallest element, and francium is the largest.

In the problem, we are tasked to solved for the amount of carbon (C) in the acetone having a molecular formula of C 3 H 6 O. We need to find first the molecular weight if Carbon (C), Hydrogen (H), Oxygen (O).
Molecular Weight:
C=12 g/mol
H=1 g/mol
O=16 g/mol
To calculate for the percent by mass of acetone, we assume 1 mol of acetone.
%C=
%C=62.07%
Therefore, the percent by mass of carbon in acetone is 62.07%
