Polarity Multiple Choice, Circle the best answer
1. Why is H2O a polar molecule?
a. It will freeze at polar temperatures
b. Since Hydrogen is polar and so is Oxygen, then the combination is also polar
c. The Oxygen bonds with the Hydrogen electrons, causing the (+) Hydrogen nucleus to be exposed at one end
2. Why don't the electrons give a non-polar molecule charges at their ends?
a. Charges from the protons cancel out charges from the electrons
b. Non-polar molecules don't have charged “ends”
c. Electrons don't have any charge
3. What happens if you mix two liquids, where each consists of polar molecules, and the liquids don't react chemically?
a. The combination turns to a solid substance
b. The combination becomes a solution
c. Such liquids will not mix
