With each set of elements and their electronegativities, determine if the electrons will be shared equally (non-polar, NPC) or unequally (polar, PC) between the two atoms when they bond together. For polar bonds, use 8* or 8 to
indicate the resulting slightly positive and slightly negative atoms, respectively. Then, use an arrow (+-> or <--+)
above the bond to show the resulting direction of polarity in each bond.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other
