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

Some fats are called "saturated" fats because __________. Select one: a. their carbon skeleton is bent to form four fused rings
marin [14]

Answer:

All carbons in the carbon skeleton contain the maximum number of hydrogen atoms

Explanation:

Saturated fats are class of compounds having all the fatty acids containing only single bonds. In other words, carbon skeleton has only single bonds.

Unsaturated compounds undergoes hydrogenation to form saturated fats.

In hydrogenation, hydrogen atoms are added to the carbon attached to double bond. After become saturated, no more hydrogen atoms can be added.

Therefore, it can be said that in saturated fats all carbons in the carbon skeleton contain the maximum number of hydrogen atoms.
