Katrina M November 7‚ 2013 Osteomalacia Osteomalacia is a disease of the bones‚ caused by a Vitamin D deficiency. Because patients with this disease have bones that are soft‚ they are more likely to bow and fracture than stronger‚ healthier bones. This disease can occur in children‚ in which case it is called Rickets. Because Osteomalacia is caused by the lack of Vitamin D‚ easily accessible in our diets‚ it can be turned around and cured. Osteomalacia affects people of all ages‚ and

NAME-FOSU-MENSAH EMMANUEL ID NUMBER-10372921 VITAMINS Vitamins are organic compounds which are needed in small quantities to sustain life. We get vitamins from food‚ because the human body either does not produce enough of them or none at all. An organic compound contains carbon. When an organism cannot produce enough of an organic chemical compound that it needs in tiny amounts‚ and has to get it from food‚ it is called a vitamin. Sometimes the compound is a vitamin for a human but not for some other

first discovered in England during the year 1808 by Sir Humphry Davy. He was able to separate calcium into a pure metal by doing an electrolysis process on a mixture of lime HgO‚ which is mercuric oxide. However‚ Sir Humphry Davy was not able to do this until after he found out Berzelius and Pontin electrolysed lime into mercury which constructed calcium amalgam. Although he discovered calcium in 1808‚ calcium metal was not available in large amounts until the beginning of the twentieth century. Before

OBJECTIVE To investigate the vitamin C content of different fruit juices. To identify which fruit juices has higher vitamin C content and the lowest vitamin C content. To determine the standard curve of vitamin C based on percentage of vitamin C. To differentiate between fresh juices and carton juices. To consider the reliability and validity of the results. PROBLEM STATEMENT Which type of fruit juices has the most vitamin C content? HYPOTHESIS The smaller the amount of the fruit juices

a difference in the amount of calcium carbonate in brown versus white chicken eggs. Background: Calcium carbonate (CaCO3) is a component of seashells and eggshells that gives them their strength and hardness. Because calcium carbonate is a base‚ it will react with acids to form a salt and water. The complete reaction of calcium carbonate with hydrochloric acid is: CaCO3 (s) + HCl (aq) ( CaCl2 (aq) + CO2 (g) + H2O (l) The portion of the shell that is not calcium carbonate does not react with

The Importance of Calcium Ions Alyssa Foels 12 February 2015 Kilfe Calcium is a cation‚ a positively charged atom‚ and it is essential to all living things. It was first discovered in 1808 by Humphrey Davy. When forming an ionic bond with other elements‚ calcium loses electrons to make its valence shell stable. This means that it has more protons than electrons‚ making it have a slight positive charge (Calcium). Calcium has many roles and functions in the human body. Calcium ions are the most

The solubility of calcium hydroxide Aim: to find out the solubility of a substance that only partially dissolves in water. Method: place about 100cm3 of distilled water in a flask and add about one spatula of solid calcium hydroxide. Stopper the flask and shake well for one minute. Leave to stand for at least 24 hours. Titrate 10cm3 samples against 0.05 mol dm-3 hydrochloric acid solution using methyl orange as an indicator. Obtain enough results to calculate an accurate average‚ and then
