Yes. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
Since a percentage is out of 100, do the % / 100
Divide the percent by 100
Answer:

Explanation:
Hello,
In this case, since the molarity is computed by:

Whereas the solute is the hydrochloric acid, we compute the corresponding moles with its molar mass (36.45 g/mol):

Next, since the solution contains both HCl and water, we compute the volume in liters by using its density:

Therefore, the molarity turns out:

Answer:
Compound B is ionic. The electronegativity difference is 2.2, which can be determined by subtracting the electronegativity of Element Y from that of Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.
Hope that helps.
Answer: V = 16.1 L
Explanation:Using Ideal gas law formula PV = nRT, we will derive for Volume. V = nRT / P
V = 0.34 mole ( 0.0820574 L.atm/ mole .K)(321 K ) / 0.5567 atm
= 16.1 L
