Magnesium oxide

A strip of magnesium (Mg) ribbon was cut with a scissor. Said piece had a length of 6 cm, and a weight of 0.071 g. The magnesium piece was rolled into a compact ribbon. After that, with copper turnings the mg piece was covered. Next, 700-mL of water was placed into a 1000-mL beaker. Then, the copper-wrapped magnesium was placed in the beaker. A 100-mL graduated cylinder was filled completely with water. After, said cylinder was covered with a small piece of paper towel over the entire rim, and…

Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

INTRODUCTION Worldwide, air pollution is a growing threat to human health and the natural environment. One of the major effects of air pollution is acid rain and it is caused by sulfur dioxide (SO2) and nitrogen oxides (NOx) gases. The combustion of high sulphur content fossil fuels can release harmful toxic gases into the air and therefore pose serious environmental problems. Coal, oil and natural gas are major energy resources available in environment where as fuel combustion processes and…

Pyrite, also known as fool's gold, is similar in color and shape to gold, and is easily mistaken for gold because it generally occurs naturally with gold. Pyrite, though, can be easily distinguished from gold by running some simple tests and doing some simple observations. Pyrite can form in many areas and shapes, the larger crystals can be perfectly formed into intriguing cubes, penetrating twins, and many other fascinating forms, while the smaller crystals can give of a shimmering or…

In Webster’s dictionary the definition of Environmental Science states that, it is “the branch of science concerned with the physical, chemical, and biological conditions of the environment and their effect of organisms”. In the experiment Environmental Science deals with how the human body will be affected in the environment with or without using electrolytes during an exercise. While conducting the experiment Aleckzar used his brother Alekczar to see if there would be a significant difference…

Ding dong. I rushed towards the door as soon as I heard the whistling sound of the doorbell. My neighbor and my best friend stood tall at the door with a soccer ball resting on his hips against his palms, inviting me to play soccer as he did every day. Once the fiercely hot burning sun started to set and the sky turned from bright yellow to a delightful mixture of orange and pink, I tied down my soccer shoes and rushed towards the ground with him, inviting our other friends on our way. We got…

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…

The removal of carbon dioxide in Recirculating Aquaculture Systems (RAS) has been an important topic of research due to the increasing amount of recirculating aquaculture systems being employed in the aquaculture industry. Carbon dioxide, as well as ammonia, are excreted by the fish and can be present in high quantities. Elevated levels of CO2 accumulation within the recirculating water could have toxic effects on fish. The maximum level of CO2 and ammonia that can be present in the tanks…

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…
