Answer:
Solubility refers to the maximum amount of solute that dissolves in a given amount of solvent at a particular temperature Factors Affecting Solubility 1. Effect of Temperature For some substances to dissolve in a given solvent, heat is absorbed. The reaction is endothermic. In this case, an increase in temperature increases solubility.
Explanation:
Answer:
mass of calcium chloride = 290.49g
mass of water = 494.61 g
Explanation:
The percentage of calcium chloride in the mixture is 37.0%
It means in each 100g of mixture the mass of calcium chloride = 37.0 g
if the total mass of the mixture = 785.1 g
the mass of calcium chloride =
= ![\frac{37X785.1}{100}=290.49g](https://tex.z-dn.net/?f=%5Cfrac%7B37X785.1%7D%7B100%7D%3D290.49g)
The mass of water = 785.1-290.49 = 494.61 grams
Answer: true
Viewed simply, electrons are arranged in shells around an atom's nucleus. Electrons closest to the nucleus will have the lowest energy. Electrons further away from the nucleus will have higher energy. An atom's electron shell can accommodate 2n2 electrons (where n is the shell level).
