Why does oil not dissolve in water? O A) Oil is an extended structure, and water is made of polar molecules

B) Oil is a extended structure, and water is made of non polar molecules

C) Oil is made of non polar molecules, and water is made of polar molecules

D) Oil is made of polar molecules, and water is made of non polar molecules

C. Oil is made of non-polar molecules, and water is made of polar molecules.

Explanation:

Non-polar molecules = hydrophobic (water-fearing, doesn’t readily dissolve in water)

Ions & Polar molecules: hydrophilic (water-loving, does readily dissolve in water)

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
