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:
If there is 0.66 moles of iron(III)oxide produced, there reacte 0.99 moles of oxygen (O2)
Explanation:
Step 1: Data given
Number of moles iron (III) oxide (Fe2O3) = 0.66 moles
Step 2: The balanced equation
4Fe + 3O2 → 2Fe2O3
Step 3: Calculate moles of oxygen (O2)
For 4 moles Fe consumed, we need 3 moles of O2 to produce 2 moles of Fe2O3
For 0.66 moles Fe2O3 produced, we need 3/2 * 0.66 = 0.99 moles of O2
If there is 0.66 moles of iron(III)oxide produced, there reacte 0.99 moles of oxygen (O2)
Answer:
A
Explanation:
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane
