Carbonated water

Introduction The Johnstown Flood which was one of the worst disasters ever happened in U.S. history by far which was also the most famous dam failure. Johnstown is situated about 50 miles east-southeast of Pittsburgh, in the Allegheny Mountains, in the southeastern Pennsylvania. There was the “South Fork Hunting and Fishing Club” whose members included Andrew Carnegie, Henry Frick and Andrew Mellon. The club had bought the abandoned earth fill dam and the reservoir known as Lake Conemaugh.…

laboratory report is, “How is the rate of dissolving sugar affected by changing the temperature of the water, changing the rate of stirring, and changing the size of the crystal?” The independent variable of each laboratory experiment is different, however they are all being changed to get consistent and effective results for one dependent variable. The three independent variables are the temperature of water, rate of stirring and size of the crystal and the dependent variable of the all the…

negative influences and uses for each. After that, I will summarize the topics one by one. The Amazon River is the second longest river in the world at almost 4,000 miles. It is also one of the widest rivers; six miles wide at some places. It collects water from 40% of South America in the form of tributaries. Tributaries are rivers or streams flowing into larger rivers or lakes. The Amazon River helped in transportation before Europeans arrived…

The water that is pumped into the ground should be separated after the procedure of fracking. Notwithstanding, some of the time it doesn't ascend to the surface yet rather leaks through the ground towards other water sources like waterways, lakes and even the ocean. The chemicals that are in the water blend can bring about issues for animals and plants living in the water or depending on it for their survival. They can likewise bring about issues for individuals who are drinking the water if the…

“Mowing the lawn is a time-consuming chore”, Deandre says. He states If you have a big yard it is a difficult task to complete. Then he said there is more to mowing the laws than just cutting the grass. First you have to make sure there is nothing in your lawn that will ruin your mower. Making sure that large sticks, balls, or outdoor items are out of the way of the mower is important, to make sure no problems are occurring, he explains. Mowing the lawn is like a never ending tunnel that gets…

Table 1, shows the exact chemicals used to prepare silica solution, zinc acetate solution and zinc nitrate solution. For the zinc acetate, adding 2-propanol to the hydrated zinc acetate will result in a white solution with some precipitations of zinc acetate in the bottom of the beaker, then by adding 2.1 grams of diethanolamine, ratio is 1:1, the solution will be transparent; due to the effect of diethanolamine which increases the pH of the solution, make it basic. Dissolving zinc nitrate in…

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…
