Calcium carbonate

drinks affect the color of your teeth using egg shells and a variety of drinks is the closest to doing it with real teeth. Egg shells are close to teeth because they are both made of calcium and stain the same way. The only difference is the fact that eggshells are made of calcium carbonate and teeth are made calcium phosphate. That difference only affects the brittleness of the eggshells so that won’t negatively affect the…

atmosphere and forms carbonic acid, which releases hydrogen ions, therefore reducing the pH. This change affects the organisms - such as crabs - who have shells and other exoskeletal body parts made of calcium carbonate and diffuses them, it also affects the internal organs.…

The article “Hidden Battles on the Reefs: How Will Coral Reefs Fare in a Changing Ocean?” was written by Tom DeCarlo and was published in Volume 51, Issue 2 of the journal Oceanus in 2016. I accessed the article through the University of West Florida’s library’s website by searching for the Opposing Viewpoints in Context database under the “A-Z Database List.” Once in the database, one can search the title of the article in the search box to locate it. DeCarlo intended this article to be read by…

Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…

My group had been given a specific task to investigate according to the lab manual1. We were employed by the Environmental Protection Agency as chemists. Our task is to identify an unknown compound that was found in a nearby landfill. In this laboratory, the unknown compound was given to us by our TA. The main goal of this experiment was to correctly identify the unknown compound. We also wanted to discover as many chemical and physical properties as possible. Physical properties are those that…

consists of Gastropod Limestone, Upper Clastic, Middle Limestone and Lower Clastic. Gastropod limestone is typically dark gray or white when exposed, and the new rocks are in either gray color or sparkly crystals, indicating the calcium carbonate. The grains of the carbonate stones vary from fine to sand-sized. This member of the Kootenai formation preserves fossils such as gastropods that date back to the late Cretaceous period. Gastropod Fossil is from the mollusk class, and it leaves spirally…

Respiration (Short-term storage) Carbon that is stored in plants, animals and all living things is released back into the atmosphere during the process of respiration. Energy is required for all living things to carry out life processes therefore stored glucose must be converted to energy by respiration. Oxygen is used to break down carbon stored as sugar for energy by the process of respiration. Carbon dioxide is released as a waste product back into the atmosphere C6H12O6 + 6O2 → 6CO2 + 6H2O…

The active ingredients/chemical compound present in the involved antacids Medi-first, Gelusil, Acalak and Alka-Seltzer are listed respectively: calcium carbonate, aluminum hydroxide/magnesium hydroxide, calcium carbonate and sodium bicarbonate (provided in Table 2). The effectiveness of each antacid listed above was tested and calculated in the same manner. Phenolphthalein indicator was used because of its ability to express the…

the stomach acid can aggravate and cause inflammation to the stomach; this leads to indigestion or heartburn. Antacids are medicines that can relieve symptoms of indigestion by neutralising the acid in the stomach. They are made up of bases and carbonates and can be taken as a liquid or a tablet. Another way to minimise the risk…

In hot water appliances, a scale (or precipitate) of calcium carbonate may build up on the heating element. Scale build-up in the water heater can slow the heating process and increase the energy usage. This suggests that change in temperature may alter the solubility of solutes. The aim of this investigation is…
