Polymer chemistry

I’m contacting you about the concentrations of the two copper (II) sulfate solutions that you were unable to correctly identify. The good news is that, for both samples, we were able to accurately determine their concentrations using Beer’s Law, a well-established law that governs the relationship between a solution’s concentration and the amount of wavelength the solution can absorb under standard conditions. Before going any further, though, let me fill you in on some of procedures and…

Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items…

The NASA Antares Rocket exploded out of the air, after it was clearly safe to launch. 5,000 pounds of supplies and more than 200 million dollars were wasted. Heading to the space station on the rocket were several experiments given by the Chinese, Russians, Americans, and Australians. They were supposed to be tested in space to examine their effects in space however, after the explosion, the experiments need to be returned back to each country accordingly. The Chinese will get LB (mineral oil),…

by which various chemical substances combined with each other could be explained nicely if one assumed that chemical combination was the group together of atoms possessed of definite weights” (Chang 135). Thomas Thomson wrote in his history of chemistry “the atomic theory first occurred to Dalton during investigations of olefiant gas and carbureted hydrogen gas…Dalton found that if the amount of carbon was the same in each compound, then carburetted hydrogen gas contains exactly twice as much…

down to his office to discuss the idea that my high school was going to cut the AP chemistry class for the following year and I had to pick a new science class for my junior year. When I asked why he told me that there were only eleven people signed up for the class and that they wanted fifteen to keep it open. To be fair it was understandable that most people would not want to sign up. Many found honors chemistry to be incredibly difficult and would be happy to be rid of it once they finished…

Imagine walking down a long row of cages. In every cage there is a terrified animal. The animals range from birds, rodents, and fish to dogs and cats. Although each animal is different, they all have one thing in common: they are lab subjects. Every animal is petrified while cowering in the corner of their cage. The animals also writhe in pain because of the drugs that are coursing through their bloodstream. The animals have never experienced what it is like to be loved and cared for. They only…

The Power of Knowledge Have advancements in knowledge changed the way people think about science experiments and the things scientist are creating? The people rely on these advancements and do not notice the effects they are having on them and their lifestyle. The advancements in science caused the people of the world to be lazy, cause harm to animals, and causing outrageous inventions to be invented. New technology has caused the people of the world to be lazy. The people in the United…

My earliest memory of science is from 5th grade in Mr. Kern’s class. I remember we had a unit on sea creatures, and we got to take care of and study fish and crawfish. I loved this activity because it was so hands on and we were the caretakers of the creatures, so we did all the work. It was really our own experiment, not just something out of a book. We all loved coming into class in the morning and running to see our new pets, and one day I noticed my crawfish had lost its shell. We learned…

All the materials were purchased from Sigma-Aldrich and used as received unless otherwise stated. Reaction (1) How to make Sodium Azo-Tetrazolate--Pentahydrate (SAT) Approximately 2.15 g of Aminotetrazolate monohydrate was added to approximately 62.5 ml of 2 M sodium hydroxide. While being stirred, the solution was heated, increasing its temperature up 10 degrees Celsius, up to 60 degrees Celsius. Over a one hour time period, potassium…

dosage, acids and bases, matter, chemical and physical properties, and etc. Pharmaceuticals are made of elements that are apart of the periodic table. That happens when combining two or more elements together causing a chemicals reaction. Also in chemistry is a law called the Law of Conservation of Matter which is used to determine chemical composition in compounds and chemical reactions. To determine this you would need to use a process called stoichiometry. (SC1) Pharmaceuticals is the…
