Calcium carbonate

Dianne Termine Honors Chemistry Period 5 Group: 22 Topic: Dissolving Alka-Seltzer in Different Liquids Due Date: September 30, 2016 (2) Background Research The topic of this experiment is investigating and researching whether different properties in different types of liquids affect the amount of time it takes for an Alka-Seltzer to dissolve. The independent variable would be the amount of liquid being used to dissolve the Alka-Seltzer pill. The dependent variable would be the amount of…

water flow to the lake then it would harm its ecosystem. 8. Handling tailing The order of stacking material can influence the acidity of the tailing. Placing sulfides to maximum contact with the surrounded are can produce maximum acidity compare to carbonate rock. 9. Bactericides The purpose of the action is to prevent the conversion of ferrous to ferric iron by using anionic surfactants. Bactericides can be sprayed by hydro seeder but this method is not for long term solution. It helps to…

Coral Reefs One of the world’s most species rich and bio diverse ecosystems are the tropical coral reefs. Emmysarus, a staff writer/ blogger for Scribol stated in their article “The World’s Most Endangered Ecosystems: Coral Reefs, “Unfortunately, areas which are home to the richest biodiversity often suffer from the greatest amount of damage and disruption”. These “rainforests of the sea” are home to thousands of species of fish and invertebrates that live among the hundreds of different and…

preparation allowed for an observation that impacted the direction of my research. During sample degradation, unprompted, I recorded a chalky characteristic present in a small number of samples. The chalky quality was determined to be calcium carbonate indicative of warm water. This observation altered my initial charter from researching land temperatures to focusing on ocean temperatures. My research experience was gratifying and confirmed my decision to major in…

E-number food additives, their chemistry and role in food Since the dawn of time, humans had using several simpler and yet natural food preservation techniques such as preserving meat using salt, or immersing onions and cucumber in a jar of vinegar to keep the food fresh and last longer. The method of preserving food had been evolved over a significant period of time. (Heldman, 2003) Food additives are either a natural or synthetic substances which was added intentionally to food to improve the…

clear parts of the ocean. Corals live closely together in groups expressing their bright colors that stand out so nicely. Many people consider coral reefs to be very diverse and productive than anything on land. Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves to the coral already there and develops lots of coral reefs grouped together. Photosynthetic algae called zooxanthellae live in the…

Stone was a major building material for temples, bowls, statues and sculptures. In many cases, Egyptians chose to cover the art pieces made of stone in a layer of paint, which was made from pigments. Those pigments consisted of minerals like calcium carbonate and azurite found in the Nile and the surrounding desert. A range of colors from white to yellow to black were available to the artists. However, the colors scheme of the river, blue and green, were the predominant shades in some of the…

• According to the Food and Agriculture organization: “Food safety is about handling, storing and preparing food to prevent infection and help to make sure that our food keeps enough nutrients for us to have a healthy diet” In other words, food safety is not just about eating balanced and healthy food, but it is about eating safe food and avoiding any kind of food borne diseases, most common: 1- Spongiform encephalopathies • Campylobacter • Escherichia coli infections • Salmonella • Shigella…

to coral bleaching, it’s the rising acidity levels in the ocean. the rise of acidity in the oceans has been connected to the increased levels of carbon dioxide. When the seawater becomes more acidic, the coral has a hard time rebuilding their calcium carbonate skeletons. If the water is too acidic, it will cause destruction among already preexisting…

these ions into the water. These released ions dissolve in water and then react with various elements, ions and compounds that come into contact with the water, which in some cases can become a nuisance. When trying to wash your hands or dishes, calcium reacts with soap to form soap scum. This soap scum leaves hard water spots on dishes and leaves an uncomfortable film on your…
