means that there was some residual impurities left over from other steps. Every other reagent has a higher melting point‚ so it makes sense that it would be higher if the product wasn’t pure enough. They most likely contaminated the sample during the suction filtration‚ meaning that the crystals didn’t dry long enough. When water was supposed to be added drop – wise to make the solution cloudy‚ the solution was already cloudy‚ so the problem was evident there. Percent yield : See attached sheet Limiting

Newton’s Third Law can be explained in many different ways but all of them relate to the same concept. Newton’s third Law states that for every action‚ there is an equal and opposite reaction. This means that in each interaction‚ there is a duo of forces acting on the two interacting matters. The size of the forces on the primary object matches the size of the force on the following object. The course of the force on the primary object is differing to the direction of the force on the succeeding

syringe are referred to as manual aspirations (or menstrual extractions). Those performed with the suction generated by a vacuum aspirator are referred to as a vacuum aspiration. Tools are used to grasp the cervix after it has been prepared with Betadine and possibly numbed. The cannula is carefully inserted through the cervix into your uterus. The actual evacuation is performed by applying suction to the syringe or via the machine. The procedure takes a few minutes to complete. There is a small
