Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By

catalyzes the substrate molecule into a product. Enzymes have the capability to break or build compounds which keep cell systems functioning. For example‚ our digestive tract has catabolic enzymes which break apart food for storage and reuse. Our lab experiment studied the relationship of benzoquinone production when altering the pH and temperature of the reaction‚ as well as enzyme and substrate concentrations. We used a Spec 20 to evaluate absorbance at 540 nm. Absorbance represents rate of

Linear conduction heat transfer Heat is applied to one end of a bar which results to an elevated temperature at that end and causes the heat to flow towards the cooler end. This will make a gradual increase of temperature at the cooler end until an equilibrium temperature is established. Usually‚ the changes that occur within the bar is not instantaneous and will be different at both end. 2. Radial conduction heat transfer Fluid motion that resulted by force over the surface by an external source
