Distilled water

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 (…

Now that I finally had my Costa Rican money in hand, I was prepared to start the ten day adventure. Although I could not understand the energetic conversations all around me, I could tell that people were happy. It was such an infectious feeling. We pushed through the glass doors, the atmosphere from inside the airport, to just a few steps outside was so different. The Costa Rican sun kissed my pale-skinned cheeks, and the chatter of people could be heard. Natives were yelling out, “Pura Vida,”…

Organic food is better than conventional food for many reasons. First, the conventional food has a big size, and it remains for long time. For example, conventional food will not get expire quickly. It could remain 2 times more the organic food. Conventional food such as crops gives a more quantity than organic food. It might be true that conventional is bigger and remains long time. However, Organic food does not have chemicals and Genetic engineering. Chemicals have a strong effect on…

whenever two chemicals react together you can’t lose any of the atoms. So lets say you have a chemical reaction of H2O + NaCl, which is water and table salt, it could go to NaH2 +ClO, but it can’t lose any of the atoms it started with or gain any new ones. The Law of Conservation of Mass governs how a chemical reaction happens because if the chemical reaction of water and table salt happened and it lost a hydrogen atom, it could make something completely different and the physical properties…

Crop and livestock production is a major source of two greenhouse gases, methane and nitrous oxide. The latter is produced by the leaching, volatilization and runoff of nitrogen fertilizers and the breakdown of crop residues and animal wastes. Through burning of biomass, agriculture also releases large quantities of carbon dioxide into the atmosphere. Agriculture also stands to suffer adversely from climatic change. In tropical environments the effects of climate change on agriculture and hence…
