Answer is no, oil is not soluble in water.

Reason: oils are hydrophobic, or “water fearing.” Instead of being attracted to water molecules, oil molecules are repelled by them. As a result, when you add oil to water the two don't mix with each other.
Oil does not have any polar part and so for them to dissolve in water they would have to break some of waters hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.

Calculate the molarity of 13.1 g of NaCl in 727 mL of solution
valentina_108 [34]

Answer:

The molarity of the solution is 0,31 M

Explanation:

We calculate the weight of 1 mol of NaCl from the atomic weights of each element of the periodic table. Then, we calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter)

Weight 1 mol NaCl= Weight Na + Weight Cl= 23 g + 35, 5 g= 58, 5 g

58, 5 g-----1 mol NaCl

13,1 g ---------x= (13,1 g x 1 mol NaCl)/58, 5 g= 0, 224 mol NaCl

727 ml solution------ 0, 224 mol NaCl

1000ml solution------x= (1000ml solutionx0, 224 mol NaCl)/727 ml solution

x=0,308 mol NaCl---> <em>The solution is 0,31 molar (0,31 M)</em>

Which of the following is NOT an example of potential energy?
Diano4ka-milaya [45]

Answer:

A. car moving down the highway

Explanation:

Potential energy is when the energy is being held in, as in, it is very still, and not moving.

When a car is moving down a highway, it is releasing kinetic energy, instead of potential.
