Chemistry has been around for a very long time. Chemistry is the branch of physical science that studies composition, properties, energy, and behavior of matter. It is said that chemistry has been around since prehistoric times. This was in the form of everyday objects like pottery, cosmetics and perfumes, and extracting metals from ores. Chemistry is based on the discovery and study of elements. Some elements were known to ancient man, but most were discovered by chemists and alchemists. Some say that chemistry started in the early Stone Age when man made fire. Chemistry is the study of chemical composition and properties of matter and the reactions of that matter. The study of any living thing involves chemistry. Without famous chemists like Dmitri Mendeleev, Antoine Laurent de Lavoisier, Albert Einstein, John Dalton, and other great chemists we would be clueless to the wonderful, confusing, and very much needed world of chemistry. Before chemistry society did not know about elements, they did not know about substances like acids and metal, or the difference between gold and lead. There are many simple things that would remain unknown if chemistry wasn’t as advanced as it is today. Chemistry is important to everyday life, because everything is made of chemicals. Chemistry is outside with the leaves changing colors in the fall. The supplies used to do household chores are made from chemistry. Chemistry is literally in everything from the food you eat to the air you breathe. It’s in your soap, your emotions, and everything you can see or touch. Antoine Laurent Lavoisier is considered to be the father modern day chemistry. He had a mighty impact on the way the world views chemistry today. From identifying elements to discover... ... middle of paper ... ... has not always been put to good use. It can be used for harmful things for instance carbon monoxide has always been one of the most harmful poisoning gases to be used. Carbon monoxide is an odorless, colorless, toxic gas. Some symptoms of exposure to carbon monoxide are flu, headaches, nausea, dizziness, and disorientation. Carbon monoxide is in many of the day to day household equipment we use, such as: gas heaters, tobacco smoke, generators, gas stove, cars, buses, and other vehicles. Carbon monoxide can be very harmful to humans if overly exposed, on moderate levels it can cause angina, blindness and reduced function of the brain. Chemistry is in everything that we do. We need chemistry to survive, and our future depends on it.Without chemistry the world would not be as advanced as it is today. Chemistry and all other sciences are the building blocks of life.
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.
In 1789, French chemist Antoine-Laurent de Lavoisier (1743-93) separated 33 substances he considered elements -including light (now know not to exist as an element) and a liquid called ‘Caloric’ (now known not to exist) (Chemical Heritage Foundation, n.d.)- into metals, non-metals and ‘earths’ (Linstead, 2012, p. 115-116).
Chemistry is a branch of natural science that deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes. (University of Idaho, 2014) Molecules, as small as they seem, is in the food that we eat and present in our daily lives. Today, scientists would likely know about the history of chemistry but not how chemistry has impacted history. Many would not wonder if these molecules go beyond the chemistry concepts that they have learned. For example, would the world have been different if piperine (molecule) present in pepper had not led to the discovery of the United States? The interesting fact is that molecules have and will continue to shape the world today. In this book, the authors explain in detail how 17 specific molecules had a significant impact on the history of the world. On a whole, this book is very intriguing and very suitable for chemistry lovers as well as the general public.
After the eighth century a man by the name of Jabir Haiyan took anesthetic compounds out of herbs which were used for general anesthesia during operations or difficult procedures. Jabir is also known well by what we know today as the periodic table of elements. An alchemist by the name of Glauber sodium sulfate in the seventeenth century. He also was the first to produce concentrated hydrochloric acid and improved the process of manufacturing nitric acid. ( “history of alchemy”).These are just a few of many alchemists who I chose to describe today. Many invented minerals or elements that we still use today. If it weren’t for alchemists we would be missing many thing in todays world. Many of these are crucial elements for scientists
Chemistry is a unique thing to learn and do. Even though you have to be cautious and use exact measurements for different substances it is still fun. You can mix different substances and elements together to make a new mixture. Trial and error is often a big factor in chemistry due to the measurements needed. Failure is in chemistry a lot, but when you succeed you feel like you have learned something new.
Our knowledge of chemistry, and the many ways that it surrounds us has helped us better understand the world we live in and the ways in which we can use chemistry to better our world, and improve our exploration of it.
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.
...ree careers make sure that every day activities do not lead to the degradation of the environment. For these reasons, it is clear that chemistry is beneficial to the way of mankind.
The history of chemistry dates back to the time of ancient history to now. Ancient civilizations used technologies that would eventually form the basis of the various branches of chemistry by 1000 BC. For example, they were extracting chemicals from plants to make medicines. The history of chemistry is intertwined with the history of thermodynamics. Chemistry is very important to our world today. Without it, we wouldn’t be near as advanced as we are. Let’s take scientists for example. The scientists at St. Jude children’s research hospital; everyday they are working to find the cure to various types of cancer by mixing different chemicals and making various compounds to somehow help all the children with the big C word today. Chemistry plays a big role in things we would never think of.
This science is directly associated with chemistry through different concepts and applications. In order to be successful this division of science, a biochemist needs to have a strong understanding of atomic structure in various molecules and elements. They need to be able to understand the structure of the diverse molecules that they are working with and should be able to predict the outcome of certain chemical reactions. Furthermore, biochemists should be just as aware of certain molecules and substances that would not react well together. Ultimately, one of the biggest factors in biochemistry is being able to balance the molecules of the substance that is being created. However, biochemists not only need to be sure that the substance they are creating is balanced, but the substance created balances when combined with living organisms. If the substance created reacts poorly with the chemicals within a living organism, the outcome could very dangerous. Since there are important concepts a biochemist needs to understand, there are some specific chemistry concepts that they must apply. A basic concept they must know, as previously stated, is stoichiometry. Stoichiometry is vital to biochemists because they need to know how to balance certain substances to achieve the reaction they want. Since they are also working on the molecular
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.
The History of Chemistry is ancient, starting at 1000 B.C to present time. Chemistry has evolved drastically over the centuries. the first civilization to take over chemistry were the Egyptians and Babylonians founded practical knowledge concerning the arts of metallurgy, pottery and dyes, but didn't develop a systematic theory.
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.
Chemistry has evolved a lot over the years. The history of chemistry shapes what it is today. Just about everything you touch, wear, or even eat is related or affected by chemistry some kind of way. In the future, I think chemistry will continue to evolve even more, and will eventually become a more diverse field.
Chemistry is a huge topic, with history dating all the back to BC, a time where the country United States wasn’t even thought about yet, and now one of the few things that have advanced so far since that time period, has been chemistry. Starting from the thought of Black Magic and Alchemy being real all the way to now where Chemistry is huge with new discoveries every year, you can only begin to scratch the surface on what impact chemistry has had in our society. Chemistry is a subject that will forever be expanding, and I feel that right now we have covered very little about the mystery of chemistry.
