Aim: To compare the foaming capacities of five different commercial soaps. Apparatus: 5 test tubes‚ 5 conical flasks (100 ml)‚ test tube stand‚ Bunsen burner and stop watch. Materials Required: 5 different samples of soap and distilled water Theory: The foaming capacity of a soap sample depends upon the nature of soap and its concentration. This can be compared for various samples of soaps by taking the same concentration of solution and shaking them.The foam is formed and the time taken

and also my merging with a company called AXON. Different Ways Messaging Was Used Instead of holding a live Blueprint meeting‚ HCL decided to have all three hundred of their managers record their business plans‚ which would then be posted on the MyBlueprint portal. Once all of the business plans were posted‚ they’d be open for review by another eight thousand HCL managers. The idea was to transform the planning process into a peer-to-peer review rather than a top-down judgment. (Nayar‚ 2010)

yield versus the theoretical yield of NaCl when HCl is titrated into Na2CO3 and NaHCO3. When 0.15g of both NaHCO3 and Na2CO3 are titrated with HCl‚ then 0.165g of NaCl should form from the NaHCO3‚ and 0.104g of NaCl should form from the 0.15g of Na2CO3. Procedure: Weigh 2 samples of 0.15g of dried unknown each‚ and dissolve each into 50mL of distilled water. Add 0.5 to 1mL of bromocresol green indicator until the solution turns blue. Titrate the HCl until it turns green. Gently heat and boil out

thermometer so as to not puncture a hole in the calorimeter) to determine the heats of reaction for Magnesium (Mg) with Hydrochloric Acid (HCl) and Hydrochloric Acid with Magnesium Oxide (MgO). Then using mathematical formulas we were able to calculate the heat formation of MgO‚ which is measured in kJ/Mol. Since both reactions are in dilute water solutions of HCl it was necessary to know the heat capacity of water‚ but because some heat would be transferred to the calorimeter whose heat capacity was
