Magnesium ribbon was reacted with Hydrochloric acid in three different experiments to determine the charge on a metal ion. After running multiple tests in the three different procedures, the Crystallization method proved to be the best method for determining the charge of the metal ion by using mole to mole ratio.…
To find this formula, a strip of Magnesium ribbon was burned in a crucible over a flame from a bunson burner. After the strip caught fire multiple times with the cover on, and 10 drops of distilled water were added, and the crucible was lightly heated. The crucible was then weighed and the mass recorded. Calculations were performed and the mole ratio of Mg to O was recorded. The results of other lab groups performing the same experiment were also recorded.…

In order to measure the atomic weight of magnesium after it is consumed, it has to be mixed with hydrochloric acid. Once it has consumed it will produce hydrogen gas, which will be trapped and measured. This means that the atomic weight of magnesium will result from separating the hydrogen gas from the acid in the magnesium. The chemical equation mentioned in the introduction indicates that one mole of hydrogen gas is produced for every mole of magnesium that reacts. In this lab, there is a 1:1 ratio between the number of moles of hydrogen gas evolved and the number of moles of magnesium consumed in the reaction. Therefore, the number of moles of hydrogen gas evolved is equal to the number of moles of magnesium consumed. The atomic weight of magnesium is equal to the weight of magnesium consumed per moles of hydrogen gas evolved.…
Burning magnesium Place magnesium ribbon in a clean crucible (on a clay triangle above a Bunsen burner). Heat until the magnesium begins to burn.…
As the magnesium comes in contact with the CO2 it creates a bright burning light…
Mg2+ has 10 electrons. A magnesium atom has 12 electrons with 2 of the 12 being valence electrons. Therefore the atom will lose the valence electrons which are located on the outermost shell to stabilize itself (outermost shell) as atoms tend to do what it easiest. Since magnesium lost 2 electrons it becomes positive as it is giving away electrons to stabilize other atoms. Hence magnesium then becomes Mg2+ because it lost 2 of the 12 electrons.…
The purpose of this lab is to determine the enthalpy of reaction for the burning of one mole of magnesium in oxygen. Although the reaction is exothermic, the ∆HRXN will be determined by using calorimetry and then using Hess’s Law to manipulate the data collected to yield the answer needed.…
one can calculate the mass of the oxygen that reacted with the magnesium. To obtain good results…
Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased.…
You can find magnesium in group 2 period 3. magnesium is a solid and looks like a silver medal. Magnesium was originally discovered in 1755 by Joseph black. Joseph black was born on 16 April 1728 in the Bordeaux, France. He was one of 12 children. at the age of 12 he was sent to school then later got His medical degree in 1754. Joseph black died in Edinburgh, Scotland on December 6, 1799. magnesium is used in lots of items. it is used in white light, firework sparklers, flares and flash photography.…
Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong, silvery-white, light-weight metal (one third lighter than aluminum). In a powder, it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk, but once ignited, it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with a thickness of about 0.03mm, and weight of about 25 grams. Hydrochloric acid is a solution of hydrogen chloride in water, that is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid. Hydrochloric…

As shown in the previous history, the further the periodic table developments, it can lead to many advances in the scientific world. Currently scientist and also students use the periodic table that was created by the past scientists, but perhaps in the future the periodic table may be improved. The article shows how the periodic table was improved upon over the years. “It was Lavoisier who wrote the first extensive list of elements - containing 33 elements. He distinguished between metals and non-metals, dividing the few elements known in the 1700's into four classes. Then John Dalton made atoms even more convincing, suggesting that the mass of an atom was it's most important property.” In this quote the author exhibits the fact that the periodic table was being constantly being improved and modified.…
