of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This

head. Solution was heated strongly under reflux using a heater stirrer block for approximately one hour. During heating 4.5 cm3 of water was collected. Solution was cooled‚ placed in a separating funnel and washed with NaOH (2M‚ 35 cm3) and water (2 x 50 cm3)‚ organic layers were collected and dried over potassium carbonate and Buchner filtered. Excess toluene was removed by rotary evaporation ensuring bath temp was around 40 °C. Vacuum distillation apparatus was set up and residue placed in a

I do understand the concern about duplicate training. However‚ creating and updating these videos will actually be a fairly small task compared to updating the modules. To give you an estimate‚ if we had to update one slide in a module due to contract change‚ I could record just that one slide‚ cut out old small piece of video/audio and insert only the updated part in under an hour. I do understand that it would be additional work to upload the new video into the Knowledge Center along with updated

The city is negotiating with Howard County horse owners to lease their steeds for special events. “We won’t be housing them‚” said Goodnight (2013). “We’re not going to build stables. We’re not even going to own the horses. “We’ll be renting them by the hour for special events and I could see this happening

Experiment 3: Wittig Reaction Introduction This experiment performs a modified Wittig reaction using a phosphorus-containing Hornes-Emmons-Wittig reagent to generate an enolate anion of trimethyl phosphonoacetate instead of a phosphorus ylide. The methyl trans-4-methoxy cinnamate produced is then analyzed using melting point and 1H NMR spectroscopy. Theory The Wittig reaction prepares alkenes from carbonyl compounds by attacking a phosphorus ylide with a nucleophilic carbon atom stabilized by

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis
