    Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry

    PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium

    Stoichiometry Lab Name Questions A. From your balanced equation‚ what is the theoretical yield of your product? Theoretical yield of the CaCO3 is expected to be .69g. B. According to your data table‚ what is the actual yield of the product? The mass of the filter paper was 1.1g‚ and the total mass of the filter paper when dried with the CaCO3 was 1.8 total. Thus the actual yield of the product was .70g. C. What is the percent yield? Percentage yield is actual yield over the theoretical

    Stoichiometry lab By: James Stewart Purpose: To calculate mole ratios Introduction: There are two types of chemical analysis; qualitative analysis which is the identification of a substance present in a material‚ and qualitative analysis which measures the amount of the substance. In this lab‚ you will perform a quantitative analysis of a two-step reaction. Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation

    Stoichiometry I. Introduction/ Purpose: Stoichiometry is the study of the quantitative‚ or measurable‚ relationships that exist in chemical formulas and also chemical reactions. The calculations of a stoichiometry problem depend upon balanced chemical equations. The coefficients of the balanced equations indicate the molar ratio of the reactants and products taking part in the reaction. There are three major categories of stoichiometry problems such as mass-mass‚ mass-volume‚ and volume-volume

    Basic Stoichiometry PhET Lab rvsd 2/2011 Let’s make some sandviches! _ Introduction: When we bake/cook something‚ we use a specific amount of each ingredient. Imagine if you made a batch of cookies and used way too many eggs‚ or not enough sugar. YUCK! In chemistry‚ reactions proceed with very specific recipes. The study of these recipes is stoichiometry. When the reactants are present in the correct amounts‚ the reaction will produce products. What happens if there are more or less of

    AP Chemistry Unit 2 Notes Stoichiometry  You should understand all that is presented in chapter 3 of your text (Zumdahl: Chemistry‚ 8th edition). Some of the highlights are presented below.  Atomic Masses (Section 3.1)       Nearly every element is made up of atoms of more than one isotope for that element. A few‚ like Be‚ only have one isotope. Others can have a large number of isotopes. Tin (Sn) has ten isotopes. (No pun intended.) Isotopic abundance is determined by the use of

    The calculations completed for this experiment include determining the amount of Na2CO3 needed to do a full reaction. This was calculated through stoichiometry calculations: Molar mass was first calculated for CaCl2*2H2O Ca = 40.078g Cl2 = 35.453g*2 = 70.906g 2H2 = 1.00794g*4 = 4.03176g 2O = 15.9994g*2 = 31.9988g 40.078g + 70.906g + 4.03176g + 31.9988g = 147.01456g or 147.0 g CaCl2 1g CaCl2 * 2H2O x (1 mol CaCl2 *2H2O/147g CaCl2 *2H2O) = 0.0068 mol of CaCl2*2H2O Molar mass was then
