Can some one help pls give a 70 points When solids dissolve in water, they (or separate) into the atoms that formed that compound.

Electrolytes are ions in solution that are essential for . The carry . Give 2 examples of ions: and

Metals form in solution.

Cations combine with anions in solution to form that can be used to identify the of metal in that solution.

Solutions conduct __ __

Chemical reactions produce because the solution allows for electrons to flow from the cation to the anion.

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.
