Abstract Unfortunately, fertilizer naturally creates an excessive supply of nitrogen and disturbs the overall cycle that normally takes place in the soil (UCAR Center for Science Education, 2017). From human intervention alone, nearly 6 billion tons of carbon is released from cars, power plants, and trucks alone on an annual...

The carbon cycle describes the flow of carbon between carbon sources, from which carbon is released into the atmosphere, and carbon sinks, where carbon is stored on earth (Tribal Energy and Environmental Information Clearinghouse [TEEIC], n.d.). The total amount of carbon on earth and in the atmosphere always remains the...

For an emergency manager, explosions are not the most common emergency that occurs. However, they do occur and an emergency manager must be prepared to deal with it, just as with all other emergency situations. One tragic explosion in 1997 resulted in the death of three firefighters. The explosion occurred...

Water (H20) is the planet’s most abundant compound (Brown, 1998) and a major component in all living things (Brooker et al. 2010; Sharp, 2001). Water has anomalous physical and chemical properties; these properties are biologically relevant, some of them are necessary for life as well as determine the size, shape...

Introduction In this experiment, the chemical equilibrium of methyl red which is a weak acid is investigated by finding the dissociation constant. Spectrophotometry is used in each case to measure the absorbance for different concentration of the test solutions. The extinction coefficients was obtained as the gradients of the concentration...

Abstract Waste water discharged to the environment by industrial facilities has environmental consequences. These consequences can be analyzed through the help of the chemical oxygen demand lab that offers a guide on the quality of water discharged. This coupled with chemical oxygen demand values of effluents and influents suggest that...

Even if chemistry is not an individual’s chosen profession or field of interest, it must be acknowledged this ancient science is definitely fascinating. Dating back to prehistoric times, the first known chemical reaction was fire. Of course humanity at the time was oblivious to the fact this was a result...

The difference between biochemical, pharmaceutical, and diagnostic chemical reactions in healthcare is that biochemical reactions are essentially chemical reactions that use enzymes and ions of minerals and vitamins to act as catalysts in the more advanced chemical reactions. The biochemical reactions are initiated by the body and are not directly...

When most individuals hear the term “fluoride,” they correctly think of proper dental health. Fluorides and hydrofluoric acid are chemicals that contain the chemical element fluorine. This element actually has broad applications beyond dental care. It also has the potential to cause life-threatening damage to an individual. Hydrofluoric acid is...

When it comes to learning the basics of chemistry, many people often do not appreciate how these concepts can be applied to research (Puigdollers, Schlexer, & Pacchioni, 2015). Recently in class in chapter 6 we learned about gases, liquids, solids and intermolecular forces. In total, there are three main types...

Understanding how chemical compounds change state is valuable in learning how climate change can be controlled. When green-house gases like methane and CO2 are prevented from entering the atmosphere the amount of heat retained can be reduced. Molecules can be found in three states Solid, Liquid and Gas. Each state...

Hydrogen peroxide, or H2O2, is a strong oxidizer and a weak acid, which means that it participates in reduction-oxidation (redox) reactions, accepting an electron from another substance and itself being therefore "reduced." This substance, so similar in chemical composition to water (H2O), has intriguing properties that make it highly useful,...
