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

REACTION PAPER It is said that effective teacher will use both assessment and evaluation regularly to improve student learning and to guide instruction. Indeed‚ both have pivotal roles in the teaching-learning process yet‚ somehow they do differ in many ways. Assessment and evaluation measure whether or not learning and/or learning objectives are being met. One could look at assessment and evaluation as the journey (assessment) versus the snapshot (evaluation). (Sue Watson‚ 2009) Assessment requires

Cell Transport Mechanisms Essay There are two methods of moving molecules across the cell membrane‚ passive transport and active transport. Passive transport doesn’t use energy‚ while active transport does use energy. Passive transport allows molecules to move on their own according to natural laws of physics. The three types of passive transport mechanisms include diffusion‚ osmosis‚ and facilitated diffusion. Diffusion is the movement of materials from an area of most concentrated to

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
