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.

What is the difference between a weak and strong base? only some of the molecules of a weak base dissociate to produce hydrogen ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydrogen ions. strong bases result in the production of hydronium, while weak bases produce hydroxide ions. only some of the molecules of a weak base dissociate to produce hydroxide ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydroxide ions. strong bases react with acids to produce water, but weak bases do not react at all.
