1. all elements are made of small particles called atoms
2. atoms of one element are identical in their properties, different atoms from different elements differ in properties
3. chemical reactions consist of atoms rearranging in whole number ratios
4. atoms can not be subdivided, created, or destroyed
Answer:
P(H₂) = 0.8533 atm
Explanation:
n(CO) = 0.220 mole
n(H₂) = 0.350 mole
n(He) = 0.640 mole
_______________
∑ n = 1.210 moles
mole fraction => X(H₂) = 0.350/1.210 = 0.2892
Dalton's Law of Partial Pressures => P(H₂) = X(H₂)·P(ttl) = 0.2892(2.95 atm) = 0.8533 atm
Explanation:
It's so because we know that stone is insoluble, ain't it, so it takes space in water & the water level rises.
But, when a spoon of sugar is added to water, it is soluble & hence mixes with water, so it doesn't rise.

<span>A substance dissolves in water by breaking up into smaller pieces. these pieces of the same substance spread throughout the water. this process is known as d</span>iffusion.
In short, your answer would be : Diffusion.
