The NaOH is a colorless solution. HCl is also a colorless solution. The test tube heated up immediately after adding in the (HCl). (3b) distilled water is a colorless liquid. While NH4Cl (Nh4 is known ammonium) is a white powder that looked like salt and also looked glittery. The test tube was cooled down. (4a) CuSO4 is an acura blur color solution that seemed to have stuff at the bottom of the bottle…

The Industrial Revolution had mostly negative effects but there were some positive outcomes. There was good and bad situations happening to the workers such as getting paid and having a good environment. Also some workers got hurt by the machines and would get sick since the machine caused pollution. One of the positive effects during the Industrial Revolution was that the workers in the factories had a good environment that was clean and safe . Every other worker was doing their job. In…

During this lab, my main goal was to discover exactly how much phosphorus (or phosphate) is in the composition of plant food, or in the case of the Guided Inquiry portion of the lab, in two different brands of plant food. If I put it in the most concise way possible, to do this, I carried out quite a few processes that caused the components of the plant food to separate from each other. Basically, I got the phosphorus, along with some other substances, to form as a precipitate. Next, through a…

the idea of low water velocity but high water storage. (Knight, 1999). There are currently 3 main theories behind the mechanisms that cause surge glaciers; these are thermal, hydrological and the deformable bed mechanisms. However there are also other theories there are also less well studied reasons as to what causes surge glaciers or in fact surges themselves. Thermal…

then they said we stay around here to protect and warn other people and we just love Lidke Mill so we will be here forever. So don’t be surprised when your at the Lidke Mill on a Friday night when you see two shiny people moving around down by the water. You might be scared, but you might…

radish seeds, materials used were twenty radish seeds, , acid rain solution, pH strips, paper towels, two petri dishes, and tap water. The second experiment on testing the effects acid rain had on radish plant growth, the materials used were twelve radish seeds, six plastic cups, potting soil, two acid rain solutions (one with a pH of 3and one with a pH of five), tap water, UV lights, and six plastic bags. These were all materials used throughout the course of the lab. The method used for…

The experiment that I am doing is to see if the water temperature affects the reaction time of an Alka-Seltzer explosion. I believe that it will affect the time of how fast the CO2 builds up because the faster it builds up, the quicker the reaction and therefore the explosion comes faster. Alka-Seltzer is a drug that is used for heartburn and indigestion relief, along with many other things. When Alka-Seltzer was first introduced, it was advertised in comics in the newspaper in 1931. In 2006,…

Both in present times til this very day ,the mining of coal has been a dangerous but much needed job to have in the United States. Without coal , a lot of things wouldn't be possible because coal is the main reason something works. Thus in order to get the coal , miners have to dig for it and extract it from the ground. The workers have to use big machines to dig through the layers of topsoil and overburden to the layer of topsoil. When they've gotten down to the coal,and are done working on…

Ecological succession is predictable change over time in an ecosystem. There are two kinds of ecological succession, and those are primary and secondary succession. Both of these can affect a community is various ways. In the Lion King, secondary succession, which is a type of ecological succession that is a result of a disturbance which changes an existing community without removing the soil, shows up and it greatly, affects the community. When Scar becomes king, the land goes into a great…

Topic B: Ocean acidification and coral reefs Introduction • Ocean acidification is a reduction in the pH of the water in the ocean as a result of increased carbon dioxide uptake in the ocean due to humans burning fossil fuels at such a high rate. • Unless drastic changes are made in regards to CO2 emissions, the rate of ocean acidification is projected to significantly increase over the next century. It is currently estimated that without any changes the pH of the oceans will be 7.8 by 2100 (…
