The image above was taken by the Galileo spacecraft as it visited the asteroid belt on its way to Jupiter. Shown in the image are two rocky-iron bodies. The large object on the left is an asteroid named Ida. The object on the right, which measures only about 1 mile across, is named Dactyl. Dactyl is a tiny moon that orbits the asteroid Ida. Dactyl orbits Ida due to
A.
the mutual gravitational attraction between the two objects.

B.
small differences in the objects' rocky-iron compositions.

C.
electrical energy transferred between the two objects.

D.
the magnetic force field that defines the asteroid belt.

Idid a lab for chemistry where we put nails in a copper (ii) chloride solution. 1. why did the reaction stop? which reactant was used up? how do you know? 2. describe what was happening to the atoms of iron and copper during the reaction. what is this type of reaction called? 3. what would happen to the ratio of copper to iron if you had placed more nails in the beaker? if you had let the reaction go for less time? 4. what is the accepted ratio of copper atoms to iron atoms in this reaction? account for differences between your experimental value and the accepted value. write the balanced equation for the reaction.
