The nail in a jar lab

The lab we did over the past 3 days has been to find the product of a reaction of iron and copper chloride. To start this we had to mass a baby food jar, acquire around 4g of copper chloride (put it into the baby food jar with water to mix it), and put a iron nail in the jar. after letting this sit for one day we took out the nail and washed out the jar while leaving the produced copper inside of the jar. After letting this sit for the weekend we to the dried pure copper and got the mass of it and the nail. Using the mass of the nail we found out if the reaction made iron(II) chloride or iron(III) chloride. Most of the reactions made iron(III) chloride.

More Stoichiometry

Its still fun to say. Besides that though we can also use stoic. to tell which reactant (if there is multiple) is the limiting factor and which one will have excess in the equation. This will help us get the proper yield and understand how the reaction works. The limiting factor wil only be needed to be found if the problem gives you more than one reactants mass. If the equation gives 2 or more masses then you must do the standard Stoic. equation on both reactants to find the same product. Whichever reactant yields the least amount of product is the limiting factor and gives the theoretical yield. This forces the other reactant to be the excess. To find the amount of excess used in the reaction you must take the proven theoretical yield and find the mass used of the excess by using the standard stoic. equation on the product.

intro to Stoichiometry

Stoichiometry is fun to say. Also the main idea so far into this unit is to find out the mass of a product by using the B.C.E and mass of one of the reactants. To do this one must take the reactants usable mass and multiplying it by 1mol/reactants mass X moles of reactant/moles of product X product mass/1mol. this equation will give you the theoretical yield of the desired product.
