Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker‚ Add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small paper cup. Then add the 25mL of distilled water to make the sodium carbonate solution. Mix the two solutions in the beaker and a precipitate of calcium carbonate will form instantly. Next set up your filtration assembly. After the filtration assembly is ready‚ swirl the contents

Chapter 9 1) Approximately how much water do you need each day to stay healthy? Water constitutes 50% to 70% of the human body. Its unique chemical properties enable it to dissolve substances as well as serve as medium for chemical reactions‚ temperature regulation and lubrication (found in the knees and other joints of the body); it also aids in regulating the acid base balance in the body. It helps remove waste from the body and is the basis for saliva‚ bile and amniotic fluid. It is

by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts of minerals and holds them in solution. Although it is not

glands. The parathyroid hormone acts to balance the calcium level in the blood and in tissues that need calcium to function properly. When the calcium level increases‚ it will cause symptoms that point to hyperparathyroidism. The extra calcium in the blood comes from the bones so fractures can occur. Blood work as well as bone density scanning will be used to diagnose hyperparathyroidism. Treatment at first will try to correct the high calcium level by dilution with IV fluids and Lasix.

The porous bones resemble sponges‚ and the damage can cause serious injuries. Healthy bones have collagen‚ protein and calcium. They are also constantly being broken and replaced. When new bones are created at a slow rate‚ osteoporosis occurs. The disease usually affects the wrists‚ hips and forearm. Osteoporosis can be present without any prior symptoms. Simple actions can
