The element calcium’s name first originated from the Latin name “calx” which means “lime”. It was 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 the autumn of 1808, John Dalton, an Englishman, explained the results of his own studies by supposing matter is composed of atoms. He supposed that…
Calcium Carbonate is found naturally in food products. It is needed for everyday, common body activities. Calcium Carbonate is used to prevent Calcium deficiencies. Some common names for Calcium Carbonate in the medical industry are Tums, Alka-Mints, and Maalox. Calcium Carbonate has other uses besides medical purposes, such as building materials and construction, and paper, plastics, paints, and coatings. You can also find it in chalk, limestone, and marble. Calcium Carbonate is able to be extracted from marble in a pure form. It is also able to be prepared when Carbon Dioxide is put through Calcium…

By filtering and weighing the carbonate after it has precipitated, the mass and moles of CaCO3 could then be found; with these values, a molar mass of M2CO3 can be found. Using gravimetric analysis, it has been determined that the unknown Group 1 metal carbonate compound is K2CO3 (potassium carbonate).…

Around one hundred fifty years ago, two superior, enemy armies faced each other outside a crossroads town in Pennsylvania. Neither army’s commander planned to battle at Gettysburg, but the assault took on a life of its own as soldiers in blue and gray rushed to the noise of bullets whizzing past them. Here, the battle would last for three days, leaving approximately 7,000 Americans dead and 30,000 wounded. The “vain and bad-tempered” (“Killer”), man Meade was ordered to take command of the Union army three days before the definitive battle, failing to eradicate Lee’s wrecked army, managing to let the army escape across the Potomac River before it could be seized, and not following through with the Henry Wager Halleck’s orders.…

It was discovered by Sir Humphry Davy, J.L Gay-Lassac and Louis Jacques Thérnard in June 1808. It wasn’t recognized as an element until Sir Humphry Davy did its first isolation in July 1808. At first Sir Humphry Davy tried to create Boron by electrolysis of Borax, but in the end he decided to mix boric acid with potassium in a place where there was more hydrogen and he was happier with the results of Boron. J.L Gay-Lassac and Louis Jacques Thérnard also produced Boron by mixing boric acid with potassium to create Boron. At first they tried using iron to decrease the amount of boric acid at high temperatures. It was identified as an element by Jons Jacob Berzelius in 1824. Pure Boron was produced by an American chemist named Ezekiel Weintraub in 1909.…
