Answer:
Explanation:
Polar molecules interact with other molecules of similar polarity to form solutions. Non-polar molecules do not interact the same way.
Answer:
0.0102 mole
Explanation:
Use and solve proportions for these with x as the unknown value.
Answer:
B. 0.55 M
Explanation:
Step 1: Given data
- Moles of calcium chloride (solute): 1.5 mol
- Volume of solution: 2.75 M
Step 2: Calculate the molarity of the aqueous solution
The molarity is a way to express the concentration of a solution. It is equal to the quotient between the moles of solute and the liters of solution.
M = moles of solute / liters of solution
M = 1.5 mol / 2.75 L = 0.55 mol/L = 0.55 M
Friction because smooth ice provides very little resistance against objects, like ice skates being dragged across its surface.
