__**Purpose:**__ The purpose of this lab is to determine which metal is more active then other metals. Through a series of single replacement reactions, you can rank the highest to lowest metal. __**Data:**__ The solids being used are Copper, Zinc, Aluminum, and Iron The solutions used are Pb(NO3)2, FeCl2, CuSO4, AgNO3, and HCl Copper only reacted to AgNO3 Zinc reacted to Pb(NO3)2, and CuSO4, AgNO3 Aluminum reacted to none of the solutions Iron reacted to CuSO4
 * Rank || Metal ||
 * 1 || Zinc ||
 * 2 || Lead ||
 * 3 || Copper ||
 * 4 || Silver ||
 * 5 || Iron ||

__**Conclusion:**__ This lab shows us that over the series of reactions, Zinc has the highest reaction activity, as you work your way down the ranks, the metals have less of a reactivity than the one above it. The lowest ranked metal was Iron. We were able to determine the ranks due to the single displacement reaction, so when the metal came into contact with the aqueous, if nothing happened then the metal has a less reactivity than the metal in the aqueous. If there is a reaction, and something occurs visually than the metal that was put into the aqueous has a greater reactivity then the metal in the aqueous.

__**Purpose:**__ The purpose of this lab is to test a hydroscopic ionic compound to determine its water of hydration. __**Data:**__ __**Conclusion:**__ 1. 3.58g / 18.0mol= 0.199 g/mol 2. 6.12g/ 159.609mol= 0.038 g/mol Calculate moles of Hydrate- 5.2 g/mol Conclusion: This lab shows that by heating up the wet hydrated sample, you get the dry dehydrated sample which can be used to find out how much water is in the hydrated sample. To get the answer to one we had to take the mass of the water and divided it by 18.0 mol. To find number two, we took the mass of dehydrate and divided it by molar mass dehydrate. To calculate the moles of Hydrate we took moles of the water and divided it by the moles of dehydrate.
