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

Luca Pacioli is referred to as both the “Father of Accounting” and the “Father of Profitability.” He was the first to describe in detail the double-entry bookkeeping‚ a process that plays an integral role in the development of capitalism as it allows us to calculate profits (Fischer‚ 2000). According to Pacioli‚ the hallmark of a successful business is what he calls the profit motive. This is the notion that successful business men and women must acknowledge and be influenced by the spiritual aspects

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

major science fiction film was released that the world was still going crazy about: this film was Starwars. Spielberg was smart enough to release that the world loved starwars so much that they would be able to appreciate and love the homage to George Lucas’ film Starwars. In E.T. The Extra-Terrestrial Elliot plays with Starwars figurines‚ which is something that many children of that decade also did. This allowed the audience to put themselves in the shoes of Elliot and imagine themselves becoming friends

Mean Streets is Scorsese’s breakthrough film‚ his first financed by a major studio – Warner Brothers‚ though it’s not exactly a blockbuster-budget affair. Charlie‚ the film’s protagonist‚ struggles to maintain his sense of Catholic values despite being in the world of the petty Mafiosi – he’s not a made man by any stretch of the imagination‚ but he’s trying. He’s also a devout Catholic‚ who understands that “you don’t pay for your sins in church; you do it in the street – you do it at home.” He

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
