In this lab, the objective was to determine which iron ion was formed in the chemical reaction between copper(II) solution and iron by combining 2 bright box #6 nails with a CuSO4 solution. According to the ion chart, iron can only form the ions of +2 and +3, so that means the iron and copper solution reaction can be expressed in the formula CuSO4+Fe→FeSO4+Cu or 3CuSO4+2Fe→Fe2(SO4)3+3Cu for irons +2 ion or +3 ion, respectively. Next, the mass of the sample changed as it dried because it was left out by the window, meaning that some of the copper solution evaporated into gas, meaning that the mass of the solution was decreasing. Lastly, a real life application of this concept would be used in everyday cooking or baking. In order for a baker to know how to bake a certain amount of cookies, they would have to have a specific amount ingredients or else the cookies wouldn’t turn out very nice. …show more content…
These numbers were determined by adding the individual mass of all the elements in one molecule, which added up to 151.92 grams. Then, the total masses of the elements, 55.85 grams for iron, 32.07 grams for sulfur, and 64.00 grams for oxygen, were individually divided by 151.92 grams to find the percent of composition in the molecule. Next, to find the empirical formula from the experiment data, the total amount of iron lost, 0.28 grams, was divided by it's atomic mass, 55.85 grams, to find the number of moles lost. This resulted in .0050 moles. The same algorithm was reciprocated for the amount of copper gained, 0.39 grams divided by its atomic mass, 63.55 grams, which lead to the answer of .0061 moles. From these numbers, they can be compared in a ratio, 0.0050:0.0061, and when then compared to the copper to iron +2 ratio of 1:1, it can be concluded that the ratio of copper to iron in this experiment is similar and can be deduced that the iron in the experiment formed a +2

Ammonia and Oleic Acid Essay

Many chemical reactions do not go to completion. Rather, they come to a point of chemical equilibrium before the reactants are fully converted to products. At the point of equilibrium, the concentrations of all reactants remain constant with time. In this experiment, you will investigate how outside forces acting on a system at equilibrium provoke changes within the system (Le Chatelier’s principle). Introduction Early in the study of chemical reactions, it was noted that…
