Stoichiometry Lab Report

In order to create 5 grams of MgSO4 from MgO (Magnesium Oxide) and H2SO4 (Sulfuric acid), we needed to create a balanced equation to find the amount of other chemicals we would need. The balanced equation was MgO + H2SO4 --> MgSO4 + H2O. After creating a balanced equation, we found the amounts of MgO and H2SO4 using stoichiometry. The amount of Magnesium Oxide was 1.674 grams and the amount of Sulfuric acid was 6.923 milliliters. In order to create as close to 5 grams of MgSO4 as possible, we decided to ignore sig-figs, and go to the hundreds place for the sake of exactness (getting an A). For safety purposes, we also looked up what each chemical was and how to handle it without killing jack :(. Magnesium Oxide, also known as magnesia,

    The chemical elements are divided into two broad groups, the metals and the non-metals. In this experiment, you will examine some members of the metal group and identify similarities and differences in their physical and chemical properties. Metals are the elements that are found in the left of the periodic table with high electrical and thermal conductivity. Metals lose electrons to create positive ion charges. Metals have a unique shine, are prone to forming, have a high tendency to form cations, and combine with oxygen to give mostly basic oxides.

    In order to begin this experiment, first one must find the balanced chemical equation for the reaction which occurs between the aluminum and copper (II) chloride. This balanced equation being 2Al(s)+3CuCl2 (aq)3Cu(s)+2AlCl3 (aq). After finding this equation, one must use the process of stoichiometry in order to find how many grams of aluminum are needed in order to produce 0.15 grams of copper. In this experiment, the purpose was to produce between 0.1 and 0.2 grams of copper, so one should attempt to produce 0.15 grams of copper seeing as it is the average of those two numbers. The first step in the stoichiometric process which one has to complete is finding how many grams of copper are in one mole of copper.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.

    In this project, titanium(IV) ethoxide, Ti(CC2H5)4, Cobalt(II) nitrate, Co(NO3)2.6H2O, Iron(III) nitrate-9-hydrates, Fe(NO3)3.9H2O, and strontium nitrate, Sr(NO3)2 are needed to prepare both non-substituted strontium ferrite and substituted strontium ferrite. In this case, non-substituted strontium ferrite acts as a control in this project to compare with the characteristics of cobalt-titanium substituted strontium ferrite. The main objective of this project is to compare the effect of substitution of cobalt-titanium ions to strontium ferrite using the control, the strontium ferrite without any substitution.

    INTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture. The principle of gas chromatography can be explained as following: A micro syringe is used to inject a known volume of vaporous or liquid analyte into the head or entrance of a column whereby a stream of an inert gas acts a carrier (mobile phase). The column acts as a separator of individual or chemically similar components.

Background: Just like a recipe would call for a specific amount of one ingredient to a specific amount of another, stoichiometry is the same exact method for calculating moles in a chemical reaction. Sometimes, we may not have enough of or too much of one ingredient , which would be defined as limiting and excess reagent, respectively.

    The experiment was to indicate if the substances are acidic, base or neutral and was tested during the lab to obtain a final answer. The procedure we followed were simple: we gathered the materials and cleaned them out and then shortly after we tested the fluids with 2 Litmus paper of each color. As we finished the procedures we got result almost immediately with four out of the six being neutral and only two being acidic. The results supported part of our hypothesis as the last two were incorrect. The last two were guessed as being base and acidic but was neutral which was astonishing because rubbing alcohol showcased characteristics of being acidic which led us to believe it was, but was not supported with the data.

    In this experiment, we sought to determine what type of iron was used in the nails which we utilized in our reaction. In order to determine this, we added the said nails into a mixture of H2O and CuCl2 with the intention of reacting the two to create copper. Because of the law of conservation of mass, the creation of copper had to take mass from one of the reactants, in this case, iron. We observed the mass of the iron nails decrease between the start and the end of the lab, and we then converted that mass in grams into moles of iron and did the same with the amount of copper that we recorded after the decanting process. We used these two measurements to calculate the mole ratio between iron and copper.

    Abstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
