Option 1: When dissolved, sugar molecules have more opportunities to bond with positive-negative water molecules. Therefore, sugar dissolves faster than salt, because its component molecules are more soluble in water.
❤️
Option 2: Sugar can dissolve easier than salt because when you add 8 spoons of salt into water the salt already starts to stay in the bottom of the cup. And, when you add 30 spoons into water the sugar just starts to stay in the bottom of the cup. It’s almost the same.
Hope it helps.
Have a nice day!~ ￣▽￣❤️
Answer:
By using magnet.

Answer: Option (e) is the correct answer.
Explanation:
According to Henry's Law, mass of a gas which will dissolve into a solution is directly proportional to the partial pressure of that gas above the solution.
Mathematically, C = 
where, 
= Henry's constant
P = partial pressure
Since, concentration is directly proportional to partial pressure of a gas. Hence, more is the partial pressure more will be the number of molecules present in the liquid.
Thus, we can conclude that the statement there are twice as many gas molecules in the liquid, is true.
Answer:
I am pretty sure that I know what Anna is working on, given that she wants to find the patterns of demographic variation, is population structure. This structure deals with variations in age, gender, and other qualities of a population, and I believe that is what she wants to find out. So the answer to your question would be that population structures are the patterns of demographic variation.
