Explanation:
For example, Identify the number and type of ions formed in a reaction of calcium and carbon. Step 1: Determine the number of valence electrons for each element and whether the element loses or gains electrons. Calcium has 2 valence electrons and is a metal so it will give up two electrons.
Mg is magnesium. NO3 is nitrate. This gives you magnesium nitrate as an answer.

Answer:
6 cm Hg
Explanation:
Boyles Law: P1V1=P2V2
(100 mL)(x)=(20 mL)(30 cm Hg)
x = 6 cm Hg

Answer:
<u>Solubility of the liquid increases with temperature.</u>
Explanation:
The solubility of the liquid increases with increase in the temperature but there is no effect of the pressure on the solubility of a liquid, whereas, the solubility of gases in liquids increases on increasing the pressure above above the surface of the liquid.
On increasing temperature of a liquid solvent the kinetic energy of the particles of the solvent increases which makes particles to move faster which breaks the particles of the solute more rapidly with more energy.
Also the saturation point of a solvent can be increased by increasing the temperature of it which allows to dissolve more solute in the solvent beyond the saturation point.
