Introduction: In this experiment, calcium chloride was reacted with sodium hydroxide correspond to the following fit equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) The purpose doing this reaction was to maintain stoichiometry calculations. Stoichiometry is the process of keeping track of the quantitative relationship amid 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 inevitable 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 trammel 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 playacting a limiting reagent stoichiometry problem, one is given the starting amounts of the reactants which should be conve rted into moles. Next, the problem should be treated as devil separate problems, and each amount of moles of reactants should be multiplied by the proportion of crop to reactant. This will solve for the amount of product that can be made with each of the two paired reactants. The correct amount of product that can be produced is the littler of the two values since that reactant limits the production of product. In this lab, the theoretical dismantle down of the equation is found by using the face of stoichiometry problem mentioned above, and the actual stand is how much product is real form in the lab. The percent yield, a comparison in the midst of theoretical and actual yield, is than found using the equation: pct yield = (actual yield / theoretical yield) X 100% entropy and Calculations: balance Equation: CaCl2(aq) + 2NaOH(aq) Ca(OH)2(s) +2NaCl(aq) Table 1: Results multitude of CaCl2 Added (mL)| Volume of NaOH Added (mL)| potful of Ca(OH)2 Obtai ned (grams)| 5.00| 2.97| .26|...If you wan! t to get a full essay, rove it on our website: OrderCustomPaper.com
