Chemistry is the branch of science that deals with the identification of the substances of which matter is composed;the investigation of their properties and the ways in which they interact,combine,and change;and the use of these processes to form new substances. Chemists believe that chemistry is the study of matter and the study of change. Chemistry is in our everyday life,it has to deal with the food we eat,the air we breathe,and almost everything we see or touch. The reason chemistry is so important is because it's the foundation to life, like humans and other living organisms.
Chemistry has been used for thousands of years.The first chemical reaction used in a controlled manner was fire;burning wood,boiling water,and lighting. Early societies used fire in its beginning to cook and keep habitats lit to more advanced things like making pottery,brickmaking and melting metals.Soon advancements were made to include glass making and the purification of metals. At one point alchemist were trying to turn lead into gold and trying to find the Elixir of Life through different chemi...
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
This lab used many test to determine which functional groups were present in certain substance. The Benedicts test was used to identify reducing sugars (glucose and fructose) based on their ability to reuce the Capric ions to cuprous oxide at high pH. The Cuprous oxide is reddish orange in color when shown to be at high levels by the test, and greenish when at low levels. In both the onion juice and glucose solution the reducing sugar levels were very high, because the test came back dark orange. The starch solution had relatively low levels of reducing sugar present and this was seen by the test coming back cloundy blue, green and brown.

Porton Down was established in 1916 in retaliation of the Germans using chemical warfare against United Kingdom armed forces. Porton is located near Salisbury, Wiltshire England on 7,000 acres. Porton Down consists of research facilities that conduct research on chemical and biological warfare.
Chemistry is a science that study matter, its properties, and how and why substances combine or separate to form new substances. Chemistry is part of our life. Chemistry is involved since we grow up to everything we do. Chemistry is one of the physical science that helps us describe and explain our world. The chemistry that I will mostly focus is on biochemistry. Biochemistry is the study of chemical process that occurs in living organism. Delta 9 Tetrahydrocannabinol could have affects in the chemistry science through the brain, the body, and emotions. Tetrahydrocannabinol or THC is a very powerful chemical compared to other chemicals. The molecular formula for THC is C21H30O2. Scientific research says that delta 9 tetrahydrocannabinol can
Genetics relies on chemistry to explain phenomena related to the field. The structure of DNA relies on chemistry. In fact, when James Watson and Francis Crick discovered the structure of DNA, they did so by building models based on the laws of chemistry. Chemistry also relates heavily to the structure and function of one of the main products of DNA: protein.
The study of biochemistry is one of the crossover fields of chemistry that goes in depth on the subject of and complexity of the systems within living organisms. Biochemists must know and understand the living world as well as the chemical world. Biochemistry also focuses on the molecules and systems that assist with the function of and creation of living organisms (chem4kids). Two biochemists that made a colossal impact on the study of biochemistry and genetics are Walter Gilbert and Frederick Sanger. These two molecular biologists are responsible for deciphering the genetic code and figured out how to decipher the sequence of amino acids in proteins (genomenewnetwok).
Performance enhancement drugs first came about hundred of years ago. They were first developed by the Incase of Peru in which they were to be used by soldiers to give them energy when fighting in battles. This source of energy came from burned leaves of coca trees. Today, 100 years later those same burned coca leaves are still used as a way of giving a person energy, but is now commonly known as cocaine. Many incidents related to PED’s have been recorded, but the first “recorded” drug related death in sports was in 1886 by a European cyclist. The cyclist was found to have a mixture of heroin and cocaine in his system. This athlete was very well known for his speed, which was why he was given the nickname speedball. Following that many more incidents have since been recorded.
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 mixture of all these exacting subjects, forming a degree that is very demanding and stimulating. Chemists are constantly thinking of new ways to produce viable drugs containing different isomers to improve the pharmaceutical sector using mathematical equations. Chemistry is about innovation, applying information to new areas and how to do things better than they were before, the degree appeals to and fascinates me.
The earliest knowledge of chemistry was in 3500 B.C in Egypt and Mesopotamia. Chemistry was concerned anything that was pottery, dyes or crafts that were developed but not considerable skills because no one truly understood its purpose. The basic idea of elements or compounds were first formulated by Greek philosopher during 500 to 300 B.C when people believed fire , water, earth, and air combined to form all living and non-living things. In the beginning of Christianity an ancient Egyptian and Greek philosopher were fused into the new ideas of science, starting with little experiments such as turning metal into gold or imitation of precious gems. Later on people such as Robert Boyle, Robert Hooke and John Mayow were just the few people who discovered specific things in history.
The author’s purpose in writing this book is many. One of these is to give students knowledge in the basics of chemistry. This book is an introduction to the life of chemistry itself. The theme of this book are elements, atoms, the periodic table, matter, chemical reactions, thermodynamics, DNA, electrochemistry, reaction rate, equilibrium, solutions, and much more! More broadly, the theme if this book is chemistry and its importance of it in our lives. There were many main points interesting to me, but here are a few.
the study of how food and drinks affect our bodies with special regards to the essential nutrients
Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
Chemistry is the most fascinating science to me. Chemistry applies to all things in the universe; living or non-living. Everything is made of elements which are made up of atoms of a certain atomic number. Thereafter I took AP Chemistry, I knew I had to choose a career in the field of chemistry. I understand and enjoy learning about chemistry. Chemistry is important, interesting, and ever expanding. Therefore, I must pursue a career in Chemistry.
Throughout my school career I have always loved chemistry. In Chemistry there was always a sense that there was more, there was always something new and exciting to be discovered and theories to be proven (or even disproven). Chemistry was the main subject with a real practical aspect to it during school and it is this, along with my genuine fascination with the subject, which fuels my desire to study it further.
