Materials and Procedure The materials that were used were the following: 4.268 grams of zinc sulfate heptahydrate, 2.586 grams of calcium acetate monohydrate, Analytical balance, 220 milliliters of deionized water, stir stick, two 100 milliliter glass beakers, one 250 milliliter glass beaker, filter paper, ring stand, glass funnel, and an Erlenmeyer flask. All of the materials listed above were obtained or taken into consideration before experimentation began. A piece of weight paper was…
Climate changing is affecting the way 5.2 million American Indians and Alaska Natives are living, 1.1 million of them on reservations or native lands. As these indigenous people are already profoundly poor, the fluctuations climate change brings, hits them even harder. Food and drink which are simple for us to get, is not for them. Food like salmon, shellfish, marine mammals, and the conventional crops are becoming more difficult to produce or find, which hurts these people economically,…
when Jell-O was made? There are so many cool and fun things to do with Jell-O. It also has many flavors and colors. Jell-O is really easy to make. Jell-O’s main ingredient is gelatin. Sometimes, Jell-O is even called gelatin. Jell-O is made of water, sugar of artificial flavor, and artificial sweetener. Also, Jell-O is made of boiling hides of animals processed meat, such as cows or pigs. The urban legends claimed that Jell-O was made of horses or cows hooves, but that is not exactly…
There are two methods you can use to find out how porous your hair is: A. The Float Test: Take a couple of strands of hair from your comb or brush and drop them into a bowl of water. Let them sit for 2-4 minutes. If your hair floats, you have low porosity. If it sinks, you have high porosity. B. The Slip'n'Slide Test: Take a strand of hair and slide your fingers up the shaft (toward the scalp). If you feel little bumps along the way, this means that your cuticle is lifted and that you have high…
ADIRONDACKS One of the most memorable places I have been to was the Adirondacks. The Adirondacks had a big lake with tons of houses all around it. There were all sorts of houses around it. There were also a lot of mountains all around. Here is an essay on different senses you could use at the Adirondacks. There were so many amazing sights. You could see a lot of mountains all around and a giant lake. Seeing the giant lake every single day was amazing. Every single time I saw it I was still…
DEVIATION BACKGROUND: On 07/28/2017, During the inspection of PRODUCT A on TP- 18, while the operator was transferring the coated tablets into a plastic scoop, which is used to load the coated tablets into the printer product hopper during the printing, what appeared to be a live and small gnat fly was observed inside the product bag. This was discovered after the operator pulled the product liner off the coated drum to pour the remaining tablets into the scoop. Per routine procedure, during…
between phytoplankton and zooplankton? The difference between Phytoplankton and Zooplankton is the fact that Phytoplankton are plants, while Zooplankton are animals. Zooplankton favour darker and cooler places in the water. While Phytoplankton gravitate towards the surface of the water…
the samples were then transferred to the furnace for total oxidation of carbon, hydrogen, and nitrogen. The second run through the furnace removed unwanted particulate materials. The gases from the combustion were collected into a cooler to remove water vapor; then contained in a ballast for equilibrium. At this point in time, the gases in question were separated by their respective carrier gases and concentrations could be accounted…
caused by burning fossil fuels such as coal, oil, and gas. The carbon dioxide accumulates quickly, entering the ocean and increasing ocean acidity, so fast that the organisms cannot adapt quickly enough. It is most problematic in cold water regions and places where deep water wells up to the surface, as not only would co2 rates rise faster, it is also the location for many fisheries. Coral reefs are also at risk, as they are already sensitive and the high acidity makes it difficult for coral to…
data from similar studies, such as, Chemistry 103: Synthesis of Alum, together show that the results from the experiment were about 0.5 degrees Celsius off. In the lab the hydration of water in Alum Crystals was determined. After completing the second part of the lab the mass of Anhydrous Alum and the amount of water driven off were found. The mass of Anhydrous…
