We then slowly added 25ml of chilled deionised water to the filtrate to initiate crystallization by using a measuring cylinder and a dropping pipette, once we had done this we left it for about 10 minutes to allow crystallization at room temperature. We then weighed a filter paper which we will use later in the experiment. We then collected the crystallized acetylsalicylic acid by vacuum filtration in a Buchner funnel and washed the product with a little ice-cold water. We then pre-weighed a clean, empty watch glass and labelled it with our initials and the date, we did this do we could easily identify that it was ours when we go to weigh it with the crystals on. We
One of the reasons is that, chocolate milk is healthy. It may contain more sugar and fat, but it contains the “nutrients of concern.” The nutrients of concern include most of the Vitamins, Calcium, Potassium, and Iron. Normal milk contains 12 grams of sugar while chocolate milk contains 20 grams of sugar. Now there is chocolate milk with fewer amounts of sugar, fat, and calories. “One serving of milk is equal to two ounces of cheese, one medium egg, one cup of fortified orange juice, and half a cantaloup over the course of the week.” says Buzzfeed.com.
In a cup put a tablespoon of warm water 2. Add salt and stir until it is melted 3. Then add the lemon juice and a glass of cold water recharge 4. Mix the ingredients and drink. Activity - The potion is within 5 minutes needed to mitigate or completely remove headache - If necessary, repeat the process after an hour.
Crystal violet was then added for 60 seconds before being washed off with water. The mordant, Gram’s Iodine, was added for another 60 seconds before getting washed off with water. The heat fixed smear was then washed with 95% alcohol until the wash ran clear, leading to the final step of adding Safranin for 45 seconds before being rinsed with water. The slide was finally blot dyed with bibulous paper before it was placed under a microscope to observe the color and shape of the bacterium. 2.2 Litmus Milk Reaction A milk-based, litmus broth tube is incubated and observed after 48 hours.
We rinsed the penny in acetone and dried it with paper towel. Next, we determined the mass of the penny by placing it on a balance. The mass of the penny was 2.47 grams. Afterwards, we placed the penny in a beaker filled with 20 mL of 6 M HCl. In the end we put the beaker in the fume hood and allowed it to sit overnight.
Once the cola starts to boil, continue to boil it for another 10 minutes so that the carbon dioxide is removed. When the cola has finished boiling, cool it in an ice bath and pour the cola back in the volumetric flask and use distilled water to fill the flask to compensate for the evaporated water. Using a volumetric pipette, transfer 60ml of the cola to a beaker and put the magnetic stirrer in the beaker. Submerge the conductivity probe in the cola. Fill up the burette with NaOH
This will be used at the end of the experiment to stain the colonies. Plating of Bottom Layer of Agar: 1. Loosen the cap on the bottle of 1% noble agar and microwave for about 1-2 min. While heating in a microwave, monitor the solution closely to avoid boiling over. Continue heating, while mixing intermittently, until agar is completely dissolved and the solution is clear.
From the Unknown tube professor Cooper gave me, I scratched a little on the slant surface with the sterilized inoculating loop. Then I place it on a clean prepared slide which already had a slight drop of water. The two substances are mixed together in the middle of the slide and let dry completely. One extra step of “heat fix” is necessary to adhere everything to the surface of the slide. To start gram staining, I slightly pour crystal-violet all over the slide and let it sit for 30 seconds before wash it off with water.
Furthermore you still need to add the water, with the same tablespoon, fill it with water and again add it to the blender. Take your tsp and pour vanilla in it, as done before add it to the blender. By this moment you can start putting the stove to heat in medium heat. Continue adding your ingredients to the blender by adding three to five Splenda sugar packs (as you prefer).Lastly you will need to add the eggs. Pay real close attention because this is the hardest part since you need to separate the egg whites from the yolks.
