Introduction: In this experiment, calcium chloride was reacted with sodium hydroxide compliance to the following fit equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) The purpose doing this reaction was to accomplishment stoichiometry calculations. Stoichiometry is the process of keeping track of the quantitative relationship in the midst of reactants and produces in a reaction. In a stoichiometry fuss, the coefficients in the match equation provide the correction number of moles of each substances that is unfailing 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 contain 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 contend a limiting reagent stoichiometry problem, one is given the starting amounts of the reactants which sh ould be converted into moles. Next, the problem should be treated as dickens separate problems, and each amount of moles of reactants should be multiplied by the proportion of yield to reactant. This will solve for the amount of product that can be made with each of the two pivotal reactants.

The correct amount of product that can be produced is the little of the two values since that reactant limits the production of product. In this lab, the theoretical divorce down of the equation is found by using the theatrical role of stoichiometry problem mentioned above, and the actual stand is how much prod uct is real form in the lab. The percent yi! eld, a comparison in the midst of theoretical and actual yield, is than found using the equation: pct yield = (actual yield / theoretical yield) X 100% information and Calculations: balance Equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) Table 1: Results brashness 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, format it on our website: OrderCustomPaper.com
