Intelligent Design in the Universe Essay

10071 words - 40 pages would not occur at all. All life on Earth depends upon fine-tuned solar radiation, which requires, in turn, a very precise balancing of the electromagnetic and gravitational forces.As previously noted, the chemical bonding energy relies upon quantum mechanical calculations that include the electromagnetic force, the mass of the electron, the speed of light (c), and Planck's constant (h). Matching the radiation from the sun to the chemical bonding

The Pros and Cons of Science

1797 words - 7 pages this time in my life that I realized that I did not like the subject. I struggled and stayed up countless hours at night trying to grasp terms and concepts in Biology. I found Chemistry to be a little more intriguing because it involved "hands on" experimentation. However, I soon began to change my feelings quickly when we were introduced to balancing chemical equations. Just as I had in elementary school, I was struggling to understand the

Physical and Chemical Changes + Specific Heat

878 words - 4 pages substances are different from the properties of the original substance. Observations are key in determining when a change has occurred. No equations are used in the identification of a physical or chemical change. An example of a chemical change is the burning of paper, like in the lab. The combustion of a substance will always be a chemical change because something new, smoke, ashes, light, will be produced. An example of a physical change is the

The Modeling of Salt Water Intrusion

1515 words - 6 pages the most commonly used today, with the availability of high speed computers that can solve many systems of equations in a short amount of time. Physical models find unique applications as visual aids that allow the actual problem to be scaled down to a size that is manageable and controllable. Analytical models involve solving equations where a definite closed answer is reached at the end of calculations, offering ease of calculation and a

Landolt Iodine Clock Reaction

973 words - 4 pages The Landolt Iodine clock reaction is used to show chemical kinetics and reaction mechanisms as well as the effect concentration has on reaction rates. Mechanisms are a very exact and detailed way of telling what happens to molecules at each level in a reaction. Mechanisms include things such as how the molecular geometry of the reagents change throughout the reaction and tells which bonds are broken/formed. In this reaction, two clear liquids

Spectroscopy of Atoms lab

1826 words - 8 pages of the lab. Background Introduction to Chemistry is designed for students to learn about the important topics in chemistry: atomic structure, properties of matter, chemical reactions, energy, structure, and bonding in organic and inorganic compounds, chemical equilibrium. The laboratory portion of this course is called a studio, and combines classic lab work with recitation, a question, and answer session to build problem-solving skills

Antoine Lavoisier

867 words - 3 pages answer to combustion. He laid the framework for understanding chemical reactions as combinations of elements to form new materials, or products. He concluded that combustion results from the rapid chemical union of a flammable material with a newly discovered gas, which he named "oxygen", previously known as “dephilogisticated air.” The word “oxygen” means acid producer. Lavoisier and others had found that oxygen is a part of several acids. Lavoisier

The Life of Albert Einstein

1727 words - 7 pages most recognizable scientific equation we see today, E=mc2, that since its genesis, has been instrumental as a basis for multiple scientific and technological innovations in the last century. He also created his Special Theory of Relativity that can be summarized by saying “that any measurement of the speed of any flash of light by any observer in any inertial frame will give the same answer c” (Fowler) where c equals the speed of light

Albert Einstein

1393 words - 6 pages in 1902 to support his family (kent.edu). Albert’s menial job as a patent clerk gave him a lot of free time to contemplate the mysteries of the universe. One of the greatest mysteries in mind to him was to consider if energy and mass, two very different concepts could somehow be linked to each other. In his quest to find this answer, he composed the most fundamentally important and most recognizable scientific equation we see today: E=mc2

College Application Essay on Chemistry

639 words - 3 pages I have always been inspired by the workings of chemistry and mathematics. My studies of these subjects have developed my understanding and have made me pursue my interest in these two topics. I want to take up chemistry as it involves a large amount of mathematics which I value and understand to be challenging, yet very enjoyable, as there is always an alternative route to obtain the answer. Additionally, I am drawn to the course because it is a

Gas: The Kinetic Molecular Theory

1522 words - 7 pages The ideal gas law can be used to answer equations such as these in order to find the amount of a gas that will be needed. This law is vital to transferring knowledge of gases into chemical equations. Without this law, information on gas could only be used to find more information on gases. Gases are a very simple yet complicated state of matter. The basic idea is that of the molecules that make up gas are constantly moving around by kinetic
