solution E to the solution W and stir the mixture. It should be noticed that crystals should form almost simultaneously. Next, this needs to be in an ice-bath again for another 3-5 minutes. Once the time is up, vacuum filtrate the solution and obtains the crystals from this. Make sure while vacuuming it, to add water and rinse it with about ml of water the most. Once the vacuum filtration is complete, air-dry the crystals before weighing them or getting the melting…

When snow crystals fall, they collide and attach to other crystals. Then the clumps break apart and attach to other clumps. By the time snowflakes reach the ground, they are made up of tens or hundreds of bits of snow crystals. Not every snow crystal had the symmetrical form Bentley was searching for. He also had to be wary that each flake wouldn’t last long, and so he had to…

the path of achieving your dreams, it’s not always easy. He also meets many people who will influence his life one way or another, but the two that especially influence his life is the Crystal Merchant and the Englishman. The Crystal Merchant and the Englishman are very significant in the story because the Crystal Merchant taught the boy that change is a very important factor in life and the Englishman taught Santiago that you shouldn’t yearn for the treasure that comes with your journey, but…

otherwise, he will not progress in life and will live in fearfulness, uneasiness, and unhappiness. Coehlo demonstrates in The Alchemist three different experiences with fear and why it must be overcome in life by his use of character choices with the crystal merchant, the Englishman, and Santiago. Fear can have many different types of physical and emotional effects on an individual’s life, including something as simple as an uneasy thought in the back of one’s mind, to a continuous tormenting…

to determine the rate law for the reaction between crystal violet and hydroxide ion. crystal violet hydroxide CV+ + OH- ————> CVOH Rate=k[CV+]m [OH-]n The objective for this experiment was to analyze the absorbance of the dyed molecule crystal violet using a colorimeter and the molar absorbance of the reactant. This data was used to calculate the concentration of the the crystal violet and hydroxide ions. Using the integrated…

line, as throughout the experiment not a significant amount of sugar crystals were formed. The fact that the shape of the bar graph is a straight line, represents that the mass of the chopsticks, were all identical. This straight line shows that almost to no sugar crystals were formed in any of the cups. B. What conclusions can you make from your results? From these results, I can say that neither of them had more sugar crystals grown, and at the end the mass of each of the chopsticks were…

When I arrived I was told the child will be return to the program in October. Crystal shared that Edith “LINC Coordinator” will be meeting with the parents to discuss her concerns about the child’s behaviour. I explained to Crystal to presume positive intentions and begin the discussion by asking questions, gathering more information and consider opening difficult conversations on a positive note. While it's important to be upfront with parents if the purpose of the meeting is to discuss a…

we gently put the flask into an ice bath and wait until it recrystallized. We noticed not to move the sample around or it would break the crystals inside. After that, we filtrated the solution to get the crystals out. Using a funnel and filter paper, we poured the sample into the funnel, the crystal would be remain in the filter paper. Finally, we let the crystals dry and weighted it in order to determine the percent of…

woman’s life that fits the criteria for her research. Crystal Wilson is the woman Potts chose to base this essay on because Crystal…

remove its two impurities by utilizing dissolution, hot vacuum filtration, and recrystallization. Hot vacuum filtration is performed to separate the crystal from the solution that it is present in. Hot vacuum filtration works best for this experiment because it prevents the premature crystallization of the solute, and thus lets the extracted crystal be extremely pure. For hot vacuum filtration to be used, impurity A must be less soluble than impurity B. Hot vacuum filtration allows for the more…
