Final Hours What would you want to do if you only had twenty four hours left to live. For my last twenty four hours, I would spend with my brothers; Bryce, Weston and Quinn, since we all love to go off-roading I would go buy jacked up mud racing trucks and tear up our favorite minimum maintenance roads around the outskirts of Humboldt. The reason I chose to bring my three brothers is because they all love to do some type of off-roading, so I thought they would be part of my last day. I chose…

Mercury Many studies have been performed to acquire specified effects of the toxic metal, Mercury, contaminating our ecosystems. Mercury is a toxic metal that can be fatal to human-beings and animals. Over the past years, many researchers have sampled water and different fishes to examine the concentrations of inorganic mercury. It has been studied that Mercury gets into the environment multiple ways. “Globally, approximately 6600 metric tons of Hg are emitted to the atmosphere annually, with…

Lead (Pb) is one of an important contaminant surrounding our environment. Lead occur naturally in all soil and water (1), or can be found deep within the ground located in ore (2). Although lead can be found in small quantities, there is a great quantity of lead flow in the environment that is detrimental to human beings and plants. However, despite lead is a toxic metal, there are still lots of households products contains lead; burning of paper products, discarded rubber, battery casings, and…

Atomic theory developed 2,500 years ago and evolved around the question whether or not something could be divided into forever. Greek philosophers debated this subject a lot, especially one name Democritus. He believed that something would only be able to be divided to a certain point because matter consisted of atoms and atoms are indestructible. Aristotle, however did believe something could be divided forever and did not believe in atoms. With all this controversy, one would expect an atom…

Cyclic Voltammetry of Ferricyanide Analytical Lab 1: 2410L Benjamin A. Battiste Group 2 10/14/15 Introduction: The purpose of this experiment is to use cyclic voltammetry to see how ferricyanide can be reduced to ferrocyanide. Using cyclic voltammetry a calibration curve will be created to determine the concention(mM) of an unknown solution of ferricyanide. In cyclic voltammetry, the potential of a substance is scanned starting from a certain voltage, going to another voltage, and then…

The light in neon signs are made of neon gas placed into glass tubes bent into decorative designs. Neon is used very often because it as a noble gas. This is because the every atom has an electron shell, therefore the atoms do not react with other atoms and it becomes very difficult to remove an electron because it would take much energy. When a high-voltage electrical current passes through the neon gas, its energy can remove an electron. The atoms in the tube are moving around and hitting…

The guiding question is that which changes are examples of a chemical change and which are examples of a physical change? Our claim is that 100ml water mixed with salt paraffin wax melting are examples of physical change. While magnesium strip heated, sodium hydroxide and copper chloride mixed and hydrochloric acid added to sodium bicarbonate are chemical change. For task 1, we measure 100ml of water, weigh 5g of table salt and mix the 5g of salt and 100ml of water. Stir until change is seen.…

Kiley Kern English 4 Mrs.Sites February 23, 2017 The Good Earth and the Virtuous Woman Olan and the Virtuous Woman are two very much alike women that are exceedingly alike considering the sustained laborious work that they perform in order to provide for their families. Neither Olan or the Virtuous Woman expect or need to be nurtured, they are consistently showing the people around them, their capability of remaining physically and mentally strong despite any obstacles or hardships that come…

*Both the communities of Shoal Lake 40 and the land surrounding the Marlin Mine have been environmentally affected which also affects the health of locals. In the surrounding areas of the Marlin Mine, there have been many complaints by locals that the water is being contaminated by toxic metals (Zarsky and Stanley 2013). Research encourages that there is this heightened level of metal in the river close to the mine, which puts the ecosystem and human health in danger (North and Young 2013).…

To start we will be looking at blood’s role in distribution of lead. Blood plays a major role in the distribution of lead even though it has a tendency to carry a small fraction of the total amount of lead present in a body. This is due to the fact that blood is constantly circulating and coming into contact every single part of the human body. Lead found within the blood system on average has a half life nearing only 1 month. Next is distribution and storage through the accumulation of many…
