Iron oxide

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…

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…

1. Introduction Pre-industrial revolution, humans beings used to live a primitive life whereby they used wood for cooking, warming house; as biofuel. Even later when they lived in houses, they used candles to light up their homes. Post-industrial revolution, human beings discovered new energy resources which have made life much easier to live. And the discovery of these resources (coal and oil), have also supported the advancement of new technologies e.g. automobiles, airplanes, generation of…

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…

Iron is the next commonest metal on the earth. It may be found in the sun as well as in other, different types of stars. Iron is a one of the main elements used for meteorite classification. Meteorite classification is a group of meteorites of common origin, for example a planet moon asteroid or basically the other object in solar system. A German chemist called Gunter Wanchtershauser discovered reactions of Iron sulphide(FeS) with a help of another philosopher called Karl R.Poppe. Iron has…

Introduction Iron is the foundation of the core of earth. Our very blood contains Iron. In simple words Iron is essential for life. This paper will also address relation of Iron with other types of elements and what makes it different from the others. The importance of Iron is immense in this world and there are many reasons for that. Iron is a brittle, hard substance found on the list of transitional metals in the periodic table on group 8 and period four. It is classified as a transitional…
