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

The Mysterious Benedict Society‚ by Trenton Lee Stewart‚ is a powerful work of science fiction exploring the devastating‚ large-scale mental effects of a formidable new (fictional) device. This technological element places it firmly in the science fiction genre. It is a strong work of science fiction because it explores several different outcomes‚ rather than just one‚ of new technology. However‚ it stands out from other science fiction works in two ways: it utilizes a lighter tone and different

and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue to a brick red/orange precipitate. The more red the precipitate is‚ the higher the concentration of reducing sugar in the solution tested. If more precipitate has formed‚ there are fewer copper ions remaining in the Benedict’s Reagent‚ therefore‚ the solution will appear less blue. This

17/09/2016. THE RULE OF SAINT BENEDICT The Young Nun Sarah seeks clarification about The Rule Of Saint Benedict from Abbot Benedict. The Rule of St. Benedict is a book of precepts written by Saint Benedict of Nursia (c. 480-547)‚ this rule of monastic life was written as guidance for the monks living communally under the authority of an abbot. It is a guide for the monks and nuns to live a prayerful‚ simple and Christ-like lives in a monastic community. The Rule of St. Benedicts revolves around this five

In “Imagined Communities‚” Benedict Anderson speculated that the transition from printing work in Latin to printing in a wide variety of vernacular created space for the idea of nationalism to form and initiate an alternative option to religion. Before 1500‚ roughly 77% of the books printed were in Latin‚ as estimated by French historians Lucien Febvre and Henri-Jean Martin‚ which resulted in an ever widening gap between the literate and illiterate. Once Latin was usurped by the vernacular around

compound which acts as a reference in all titrimetric volumetric analysis. A secondary standard is titrants that is standardized against a primary standard or another standard solution and are used for certain types of analysis. A primary standard is a reagent that is extremely pure‚ stable‚ it’s not a hydrate/has no water of hydration and has high molecular weight. A primary standard is used to calibrate other standards referred to as working standards. Examples of primary standards for titration of acids

Stoichiometry and Limiting Reagents Theodore A. Bieniosek I. Purpose and Theory The purpose of the experiment is to study and apply the processes of stoichiometric calculation on a controlled chemical reaction. We will be adding variable amounts of reactants in a chemical reaction in order to demonstrate the effect of limiting reagents. Based on the volumes of the reactants‚ and their respective molarities‚ we can calculate the theoretical yield of the reaction and compare it to the
