reaction that forms the compound, magnesium oxide. This reaction occurs due to the heat that provides energy to activate the reaction. A blinding white flame will burn as the reaction occurs. In this lab, magnesium is burned in an open crucible over a Bunsen burner several times until the magnesium ceases to burn. This process allows for the magnesium to completely react with the oxygen found in the open air, forming the chemical compound magnesium oxide. However, our lab did not provide us with…
Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…
substance. This can be seen in reaction #2. In reaction #2, magnesium reacts with oxygen to produce magnesium oxide. Although the students can only see magnesium and magnesium oxide, the students were informed on the lab sheet that oxygen was also one of the reactants. This reaction allowed students to see how two substances, magnesium and oxygen, react to produce one product, magnesium oxide. Students were also able to see evidence of chemical reaction taking place. In reaction #2, when…
Magnesium is a mineral that can be described in so many different ways. It is almost impossible to name every little thing that magnesium may assist in to help our body function. To start with, magnesium is roughly involved in 300 essential reactions that happen within our body. The adult contains about 25g of magnesium in their body. Magnesium has specific recommended consumption level. If there is not enough magnesium in the body, it can cause multiple problems or illnesses. The same applies…
1. The reported mole ratio of magnesium to oxygen will be too high. The experiment will have less oxidation while burning. Since there are 2 oxygen and some of the magnesium evaporates as it burns, the ratio will be higher than usual 2. Since there are some magnesium present at the end of the result from not allowing all of magnesium to react and oxidize, the ratio of Mg:O will be too high -Source of error: The first source of error happened when students lifted the lid off, sometimes he/she…
Johan Gottlieb Gahn, a swedish chemist, heated the mineral pyrolusite (MnO2) and in the presence of charcoal, found element 25, manganese in the year 1774. This silvery-metallic element has an atomic mass of 54.938049 rounded to 55 with 7 valence electrons. Manganese is a transition metal in group 7, period 4. Manganese is very flammable and dangerous with very strong intensity! It’s found in the earth’s mantle while having a melting point of 1246℉. The element manganese stimulates functions of…
environmental effects, one example being acid rain (“Air pollutants smog and acid rain 1”). Acid rain is precipitation containing harmful amounts of nitric and sulfuric…
Abstract: In this lab our main objective is to find the empirical formula of MgO, magnesium oxide. To do this first we have to make sure when we burn Mg in the crucible and it reacts to with O. This lab experiment Mg is complicated by another factor. Mg is so reactive that it reacts with N in the air so some of the Mg which is suppose to react with O will react will N instead. This obstacle can be overcome by simply adding water to the Mg3N2 to yield MgOH2 and NH3. This will undo the reaction so…
Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…
I chose to write about magnesium because I had taken chemistry before. I took chemistry in high school and we had a lab where we created really bright colors that are used in fireworks. One of them was magnesium. Using magnesium in this lab we created a really bright white light. This really intrigued me so I decided to do my paper on magnesium. Magnesium is not only used in many of our electronics, but it’s a basis for life in both humans and plants. The original discoverer of magnesium was…
