1. which of the following statements is true?
the square root of the molecular weight of a gas is equal to its rate of diffusion.
the rate of diffusion of a gas in inversely proportional to the square root of its molecular weight.
the rate of diffusion of a gas is directly proportional to the square root of its molecular weight.
the square root of the molecular weight of a gas is not related to its rate of diffusion.
2. choose all that apply. solids, liquids, and gases can be distinguished by their:

molecular weight
shape
temperature
kinetic energy
mass
density
(you can select as many that are correct, if you have to, all of them)
3. list the 4 main components of air in their molecular form.

(just go under 3 put 1, then list it, 2 then list it and so on)

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
