How do different factors affect solubility? Check all of the boxes that apply. Increasing temperature decreases the solubility of gases.

Stirring increases the solubility of solids.

Increasing pressure increases the solubility of liquids.

Decreasing temperature decreases the solubility of solids.

Increasing pressure increases the solubility of gases.

Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
