    Calcium Carbide Calcium Carbide is a chemical compound containing calcium and carbide‚ with a chemical formula of CaC2. Pure Calcium Carbide is colorless‚ but some are black or grayish-white color‚ depending on the quality. Calcium Carbide is mostly used for the production of the flammable gas acetylene‚ which is similar to the natural hormone created my plants Ethylene. Ethylene is a hormone that is used by plants to ripen fruits. In Bangladesh and some parts of South-East Asia‚ Calcium Carbide

    Calcium is one of the most abundant element in the earth’s crust at number 5. Calcium has a very high chemical reactivity so it is never found as an uncombined state in nature. It is a silvery-white metal and it is in the alkaline earth family. Calcium is needed for blood clotting and controlling cell responses in nerves and muscles.Ninety-nine percent of the calcium in the human body is in our bones and teeth. Bone tissues are renewing themselves constantly and to do that they have to build new

    William Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can

    LECTURE HOMEWORK 2 Visual MINTEQ -- Carbonate System DUE FRIDAY FEBRUARY 27th The carbonate system is extremely important‚ being central to respiration‚ photosynthesis‚ pH buffering‚ carbon budgets‚ and carbonate rock formation. CO2 is the primary cause of global warning‚ and carbonate rocks and dissolved species are the most important buffers of pH shifts in the natural environment. The carbonate system‚ however‚ can be challenging to predict without a full consideration of all species

    Survey of the Sciences Unit 4: The Science of Fireworks 7-7-14/7-14-14 What is a firework? An explosive or combustible used for display. In the 19th century the introduction of new ingredients such as magnesium and aluminum greatly heightened the brilliance of such displays. There are two main classes of fireworks‚ force-and-spark and flame. In force and spark compositions‚ potassium nitrate‚ sulfur‚ and finely ground charcoal are used‚ with additional ingredients that produce various types

    Baking soda is basically sodium bicarbonate or sodium hydrogen carbonate. Sodium bicarbonate (Baking soda) is shown as a white powder which looks like salt. Baking powder contains an amount of raising agents which are E450 Diphosphates‚ E500 Sodium Carbonates‚ and Maize Starch. By heating this up there will be a release of carbon dioxide‚ which will be put into test in my experiment to prove my hypothesis. Baking powder and baking soda both produce carbon dioxide‚ which helps raise baked products

    Leaching magnesium deficiency (Cristol 2002). It causes deterioration of buildings and monuments (Cristol 2002). Turns calcium carbonate to calcium sulfate. The calcium sulfate can crumble and be washed away (Cristol 2002). Particles which can be formed from sulfate and nitrate ions can affect respiration (Cristol 2002). Acid rain may remove soil nutrients such as calcium and magnesium from soils (Cristol 2002). It robs the soil of essential nutrients and releases aluminum in the soil‚ which
