Earth is the beautiful place to live in with nature showing its magic, its the only planet in the universe which supports life. Earth comprises of millions of spices includinghuman. Nature supports every species in its own unique way but in today 's world of modernization the natural environment is substantially altered by human intervention. Earth produces various useful biological products and large deposits of fossil fuels are also obtained from earth. But these resources are continuously…

Covering over 70% of the Earth’s surface and comprising two-thirds of the human body, water is essential to the sustenance of life (CDC, 2016a). However, only 3% of the world’s water is freshwater (WHO, 2015). Due to the limited availability of freshwater, 663 million people in the world lack access to safe drinking water (WHO, 2015). Contaminated drinking water can contain pathogenic bacteria from human and animal waste, harmful metals, and dangerous chemicals from the improper disposal of…

with copper to 97.5% zinc and 2.5% copper. Because of this, zinc will react differently with the solution than a more pure copper would. In addition, the reason the pennies were coated with a bluish green color is to protect the copper from further corrosion. https://www.usmint.gov/learn/history/coin-production 3. How could you account for what happened to the pennies in terms of a microscopic…

The environmental case study of choice is oil spillage in Niger Delta region of Nigeria. I decided to write on oil spills in Niger Delta region of Nigeria because it affects the poor and vulnerable populations who are unable to confront the multinational oil companies and government who are benefiting from the proceeds of oil exploration. The region which is home to 20 million people consists of 40 different ethnic groups and occupies 7.5 per cent of the nation’s total land mass (Kadafa, 2012).…

Animal testing has dated back to ancient Greek writing in 500 BC. Aristotle believed that animals lacked intelligence, and so the notions of justice and injustice did not apply to them. Animals were not seen to have a life or soul, and could be used in any way. Between 130 and 200 AD, Roman physician and philosopher Galen engaged in the public dissection of animals, which was a popular form of entertainment at the time (Background). Through some of this testing and experimentation, discoveries…

Heritage on wheels. That’s my take on the Ford Mustang. You cannot escape the evidential truth that Ford’s pony car has a great deal of history behind it, while it adroitly advances that legacy with each new model built. A Once-Threatened Species More than a half century has passed since the original Mustang took to the road, but not without a little drama through the intervening years. Indeed, the Mustang’s existence was threatened at least twice over that span, beginning with new federal…

production and the working force (6). The bourgeois industries expanded and increased their own capital, leaving the lower class unable to compete; Now and then the workers are victorious, but only for a time” (6). This dissonance eventually caused corrosion within the structure of the proletariat, and this struggle created the revolutionary element which eventually destroyed the bourgeois oppressors: “What the bourgeoisie, therefore, produces, above all, is its own grave-diggers. Its fall and…

C is 7.0. If the pH of water is the >6.5 or 8.5 it is considered harmful. The water sample obtained from industrial contaminants is of the pH ranging from 3.4 to 8.4, mineral acids (HCl, HNO3 etc) have pH below 3.5. Water with greather p causese Corrosion to pipe and highly basic water…

CHAPTER 1 TIN OXIDE 1.1 Introduction Tin dioxide, also known by the systematic name tin(IV) oxide and stannic oxide in the older notation, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six…

Did you ever think that, in addition to enhancing your appearance, make-up could have ugly consequences? The make-up you choose could affect various aspects of life. Cruelty-free cosmetics is make-up that is not tested on animals. The use of animals for experiments is traceable to an Arabic doctor in the second century, who first carried out surgical procedures on animals before employing them on man (Franco, 2013). Initially, the experiments were intended for the understanding of the anatomy…
