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.

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.

Throughout history, the curiosities of obtaining knowledge of facts that show the operation of general laws have resulted into the improvements of today’s society. Such curiosity of chemical reactions coiled in the minds of John Dalton in the atomic theory, Rosalind Franklin with genetics, and most importantly Antoine Lavoisier the father of modern chemistry. All who, worked extensively to acquire the understanding that fascinated them most, chemistry. Another chemist who sought after the same knowledge was Stanislao Cannizzaro. Studying organic chemistry Cannizzaro explained how certain elements lacked the hydrogen atom in what is know n as the Cannizzaro Reaction.
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
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.
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.
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.
Chemistry has been around since the earth was created, a time when computers, televisions, or simple beakers weren’t invented yet. Chemistry was always around, but it wasn’t considered a science until modern chemistry was discovered. Modern chemistry has only been around for centuries, where author Robert Boyle published The Skeptical Chemist in 1661. Soon after Robert’s publication, Antoine Lavoisier developed the law of conservation of mass, and that was the start of modern chemistry being considered a science. After this, chemistry was changed forever.
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 has been around for a very long time. Chemistry dates back to as far as the prehistoric times. If you put the amount of time chemistry takes up in a timeline, you would split it into four general categories. The four categories are: prehistoric times - beginning of the Christian era (black magic), beginning of the Christian era - end of 17th century (alchemy), end of 17th century - mid 19th century (traditional chemistry), and mid 19th century - present (modern chemistry).
In society today it is very rare to find someone who does not own a cell phone. There are ten year old children running around with iPhones. Cell phones have become such an important part of society. They have come along way with the advancements made in technology to allow these phones to do more than you would think possible. We now not only use them to contact people, but use them for social media, to take pictures, surf the web, and get information at the touch of our fingers. It is crazy to think that at one point there were no cell phones. Without the use of chemistry we would not have the cell phones that we use today. Chemistry is defined by the Holt Modern Chemistry textbook as the scientific study of the composition, structure, and properties of matter and the changes that matter undergoes. Chemistry is responsible for the batteries that are in all our our cell phones. Without these batteries there would be no phone. The battery is the main power source of the phone and without it then the phone would not work.
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.
Science and Technology has been around from the beginning of time. It evolved from the everyday efforts of people trying to improve their way of life. Throughout history, humankind has developed and utilized tools, machines, and techniques without understanding how or why they worked or comprehending their physical or chemical composition. Before we go any further a definition has to be given for both Science and Technology because they are both different in their own right even though the two are almost indistinguishable. According to the Oxford Dictionary Technology can be defined as the knowledge or use of the mechanical arts and applied sciences, while Science can be defined as the branch of knowledge involving systematized observation and experiment. Science can be further divided into three separate categories; Pure, Applied and Natural Sciences. In addition technology is often defined as applied science, it is simply the application of scientific knowledge to achieve a specific human purpose, however, historical evidence suggests technology is a product of science.
