What is in urine? Urine is about 95% water, butthe rest of the contents of urine can depending of what you've eaten, drank, breathed or been exposed to. The remainder of urine usually consists of urea, uric acid, ammonia, hormones, dead blood cells, proteins, salts and minerals, and toxins. Bile http://www.auburn.edu/academic/classes/zy/561/liver/sld009.htm POWERPOINT The principal components of bile are cholesterol, bile salts, and the pigment bilirubin.

the chemical reactions that you will observe in the lab this week. Compounds containing the carbonate ion (or the related ion bicarbonate or hydrogen carbonate, HCO3-) react with acids to give carbon dioxide (CO2), a colorless, odorless, and slightly acidic gas. For example, the reaction of baking soda (NaHCO3) with acids such as those in lemon juice or buttermilk releases carbon dioxide which causes baked goods to rise: HCO3- + H+ CO2 (g) + H2O In this equation the sodium ion, Na+, does not

protein called keratin, which is also present in nails. In hair, keratin molecules are arranged in straight bundles. These bundles are held together by disulphide bonds (-S-S-), which give strength to the hair. Disulphide bonds are made by the amino acid called cysteine. The cysteine of one keratin molecule forms a disulphide bond with the cysteine of the neighbouring keratin molecule. The more disulphide bonds there are in a strand of hair, the straighter it is. Ammonium thioglycolate: the perm salt

means fluoride is toxic for a human being. This polyatomic ion is commonly used for protecting teeth from cavity because it can react with the ingredient of teeth enamel “hydroxyapatite” and makes tooth enamel stronger so that teeth can get higher acid resistance. There are also other usages of Sodium Fluoride Ion, for example, because of its toxicity it is used to make rat poison. So sodium fluoride ion is an ionized

flakes into vial to about 1.5 cm high of the vial. Phase two is to add three to six grain of antifungal agent and yeast into the vial. Phase three is to standard water with one percent propionic acid by showering a little into a Dixie cup then uses a pipette add a few drops of one percent propionic acid to moisturize the flakes. Phase four the flakes should be converted to a blue color all through the vial. Phase five let the vial set for about eight to ten hours, if the vial is dehydrate moisturize

Alka Seltzer is a type of chemical reaction where you put water and carbon dioxide gas. Equation . When Alka-Seltzer tablets are dissolved in water, bicarbonate forms (from the sodium bicarbonate), which in turn reacts with hydrogen (from citric acid) to form water and carbon dioxide gas. “ In The bicarbonate reaction project you will find out for yourself by plopping Alkaseltzer tablets into water at different temperatures, and timing how long it ta of the bicarbonate

this experiment were distilled water and Alka-Seltzer tablets. Water contains H2O, and the ingredients in Alka-Seltzer are aspirin, citric acid, and sodium bicarbonate (NaHCO3). When sodium bicarbonate is placed in water, it dissociates into sodium (Na) and Bicarbonate (HCO3). When the bicarbonate splits apart, it reacts with the hydrogen ions from the citric acid. This forms carbon dioxide and water. When Alka-Seltzer and water react; it forms Carbon Dioxide Gas. The reactions forms when small bubbles

the importance of maintaining the pool. Chlorination: Chlorination in pools is the most common form of disinfection for swimming pools. Pools are chlorinated because chlorine is extremely effective of killing bacteria. In the form of hypochlorous acid, chlorine kills bacteria by attacking the cell walls and destroying the cell itself. There are several ways to introduce chlorine into the pool. These include: tablets, powdered chlorine, or a salt chlorine generator which converts table salt into

What is the water quality of the U-high creek based on invertebrates found in the water? The quality of a water source is determined by the measure of different chemicals that keep a balance for other life to survive in. Dissolved oxygen is oxygen molecules that have combined with water molecules. Many aquatic organisms need dissolved oxygen to respire, so this chemical is necessary for a healthy creek. A good range for dissolved oxygen would be anywhere from 4-11 ppm. PH is the acidity levels in

Acid rain is the atmospheric issue I will be discussing in this writing. “Acid rain, also called acid precipitation or acid deposition, is precipitation possessing a pH of about 5.2 or below primarily produced from the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx; the combination of NO and NO2) from human activities, mostly the combustion of fossil fuels” (Butler and Likens, 2012). I will be comparing and contrasting the indoor air pollutant tobacco smoke with acid rain. ”Tobacco smoke
