1 The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth but it is only about 60 percent as dense as Earth. Thus the gravitational attraction on the Moon is much less than it is here on Earth and a person weighs less on the Moon
2 The strength of the gravitational force between two objects depends on two factors mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled the force of gravity between the objects is doubled increases, the force of gravity decreases.
3 If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

Answer:
There would be an over population of seals and less food for the species that eat what seals eat or for their prey it can be extinction, all of this can possibly causing extinction.
Calcium chloride is a salt, which is used in household and in industries. The calcium chloride is an ionic compound which can be split in ionic form such as one cation (Ca2+) and two anions (Cl-). Therefore, the cation in the CaCl compounds is Ca2+ ions.
