Virtual Chem Lab 6-2 & 6-3 Anonymous CHM/110 June 16‚ 2014 Zamir Deen Virtual Chem Lab 6-2 & 6-3 Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between

December 19‚ 2012 Gummy Bear Lab Question- If the percent of the concentration of a solution varies‚ will the amount of water gained or lost vary in a linear fashion? Hypothesis- If the concentration of a solution varies‚ then the amount of water lost or gain will not vary in a linear fashion Prediction- I think that the amount of water lost will not vary in a linear fashion. I think the water will vary like one gummy bear would lose 4 grams while another would lose 6 grams while another would

Part 1 I decided to carry out a PEST/STEEPL analysis on MacDonald’s‚ the fast food chain. Although in their own Mission and Value statement they describe themselves as a franchise business. The STEP analysis proved to be relatively easy‚ in some was it is similar to SWOT‚ in that once a start has been made it is difficult to stop. I used a copy of their 2011 Annual Report as the basis for the analysis‚ this did make things difficult in term of economic factors as the report was mainly financial

Ice Calorimeter Determination with Mg June 18th 2013 Abstract: This experiment determines the amount of energy needed to melt ice. A spontaneous increase in enthalpy produce by combining 0.2036g Mg and 5.00mL H₂SO₄‚ ice was melted and readings were taken by using an ice calorimeter. Readings were taken before during and after the reaction were completed. The data taken shows a value of -405 KJ/mol while the theoretical value was -483.7 KJ/mol. Calculating the experimental

The Mammalian Urogenital Lab Questions 1. The urine needs to be stored in egg-laying animals so that the fetus is not trapped in pools of urine inside of the egg. This keeps the urine separate from the fetus and its nutrients. 2. The fetuses of mammals that bear their young alive do not need a urine sac and does not form urine because all of the fetuses waste is taken out through the mother either through the placenta or the umbilical cord. 3. The testes are separated from the abdominal

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was

The purpose of the first week was to familiarize ourselves with the equipment and actually conducting the experiment. The second week of the experiment was focused on gathering data for benzoic acid and for the third week‚ Naphthalene was experimented on. Upon entering the lab‚ the parts of the cathetometer were already unpacked and ready
