Why Is Calcium Chloride Powder Used Extensively As A Bleaching Agent? In simple terms‚ calcium chloride is an inorganic compound having chemical formula CaCl2 (H2O)x where x can be 0‚1‚2‚4 and 6. All the salts produced by calcium chloride powder has a unique characteristic that they are highly soluble in water. This helps in applications where you need to remove snow‚ ice‚ or frost from any surface or even simple dust removal. It can absorb moisture from the surrounding environment‚ which is also

• Profitability Procter & Gamble’s Gross Profit Margin (GPM) increased in 2010 by 2.41%‚ however it decreased in 2011 by 1.34%‚ while Net Sales continued to increase from 2009 to 2011. This trend was due to a price fluctuation in Cost of Goods Sold. The GPM directly affected the Operating Profit Margin (OPM)‚ which also increased in 2010 by 0.25% and decreased in 2011 by 1.14%. The Operating expenses were somewhat stable‚ which resulted in the OPM ratios following a similar trend as the GPM

ISE: The Determination of Chloride Unknown: #34 I. Purpose: In experiment V‚ “ISE: The Determination of Chloride”‚ the concentration of an Unknown Chloride solution‚ and the Wt% of NaCl in a sample of celery salt‚ were both determined. To determine the concentration of an Unknown Chloride solution‚ a Calibration plot is first prepared. The Calibration plot is made by first measuring a series of known concentrations of Cl- (with the same activity of the unknown solution) and obtaining

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

well as the density was calculated. The same process was performed to calculate the density of an unknown substance. The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1. A metal sphere weighing 15.45 g is added to 21.27 mL of water in a graduated cylinder

Homework 2 Solution Key Problem 1. Suppose that you sell short 500 shares of Intel‚ currently selling for $40 per share‚ and you give your broker $15‚000 to establish your margin account. Assume Intel pays no dividends. a) If you earn no interest on the funds in your margin account‚ what will be your rate of return after one year if Intel stock is selling at (i) $44; (ii) $40; (iii) $36? The gain or loss on the short position is 500 P . Invested funds are $15‚000. Therefore‚ your rate
