Introduction: In this experiment, calcium chloride was reacted with sodium hydroxide understanding to the following fit equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) The purpose doing this reaction was to feat stoichiometry calculations. Stoichiometry is the process of keeping track of the quantitative relationship mingled with reactants and produces in a reaction. In a stoichiometry fuss, the coefficients in the equilibrize equation provide the correction number of moles of each substances that is inerrant to complete the reaction. Often in a reaction, there is a narrowing reagent since the exact proportions of moles of the reactants are not present. Thus, a passing reagent is the reactant that determines how far the reaction will go before do the it to stop since there are fewer moles of it than the proportion requires. When acting a limiting reagent stoichiometry problem, one is given the starting amounts of the reactants which should b e converted into moles. Next, the problem should be treated as both separate problems, and each amount of moles of reactants should be multiplied by the proportion of growth to reactant. This will solve for the amount of product that can be made with each of the two gelid reactants.

The correct amount of product that can be produced is the small of the two values since that reactant limits the production of product. In this lab, the theoretical break up down of the equation is found by using the pillowcase of stoichiometry problem mentioned above, and the actual stand is how much product is real fo rm in the lab. The percent yield, a comparis! on betwixt theoretical and actual yield, is than found using the equation: percent yield = (actual yield / theoretical yield) X 100% selective information and Calculations: balance Equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) Table 1: Results al-Quran of CaCl2 Added (mL)| Volume of NaOH Added (mL)| potful of Ca(OH)2 Obtained (grams)| 5.00| 2.97| .26|...If you want to get a full essay, collection it on our website: OrderCustomPaper.com
