Acids and Bases are solutions, and can be found everywhere in the world. They can be found in food, drinks, around the house, and in the environment around you. Acids and Bases are used by people, animals, and even plants for many different purposes (Buthelezi et al. 634). A solution is a homogenous mixture, which is a mixture with a composition that is consistent throughout the substance (Buthelezi et al. 634). Solutions are comprised of the solute and a solvent. The solvent is the most…

Purpose The purpose of this experiment is to confirm the functional relationship of Boyle’s law through the use of a manometer. The two parts of this experiment will determine the number of moles of oxygen and the second part will determine the number of moles of nitrogen, that will lead to determine the value of R by measuring P, V, and T. Theory/Principles A physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a…

Assignment 1: Discussion Assignment Discussion Question 1 What is the difference between biochemical reactions in healthcare? Biochemical reactions occur as a chemical reaction, which naturally takes place in a living organism. It happens within a cell involving a catabolic reaction (breaking down of molecules) or a anabolic reaction (building up of molecules). The process involves a diversity of biomolecules interacting with one another in order to make up a new biochemical for a particular…

How can one element change the world? Well if it is an element like copper then it can change our whole world? Copper allowed for early humans to build new weapons which could help civilizations to win or lose in battle. Copper allowed for the modern revolution thanks to the unique qualities it has that other elements do not. Copper allowed for things such as the telephone to make long distance calls and cell phones which allow us as humans to talk wirelessly to people in another country. It…

the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) at B3LYP/6-311G** level of calculations using Gaussian 03 program package [32, 33]. Thus, this principle is pretty beneficial for the utility of electron chemistry, due to the fact HOMO /LUMO potentials involve the capabilities of proton transfer or unshared pair/empty orbital…

purpose of this experiment is to synthesize a specific alcohol by using the Grignard reaction. The product is then determined by spectral and physical properties. Introduction The Grignard reaction is one of the most important reactions in organic chemistry. The reaction involves the Grignard reagent, which is formed…

My junior year, I decided to take my first Advanced Placement class, which was AP Chemistry. It was easy at first because it was all review from the general chemistry class I had taken the previous year. Then it started to get really hard. I had drifted through all of highschool with never needing to study before and suddenly I was studying for hours every night. The stress was really taking a toll on me and I slacked off third quarter. Fourth quarter was spent reviewing and on top of refreshing…

The discovery of fire has been estimated at approximately 1.7 million years ago, and can be viewed as one of the most important discoveries of mankind. However, to the humans living on earth at that time, they were highly unaware of the true scientific reasons and causes for the bright and hot flames. With scientific research, an individual is capable of breaking down the science behind fire and truly understand what is happening to an object or substance as it is burning. In order to produce a…

Love Canal Sophie Albright The Love Canal tragedy, in 1942, caused conflict and stirred up arguments, socially, economically, and environmentally. Unwanted chemicals from various experiments and projects from different companies and groups were dumped at a waste site in Niagara Falls, New York, thinking the landfill would cause no harm. The chemicals were then, out of sight, out of mind. When the area was turned into a neighborhood, it then became evident those discarded…

CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…
