Chemistry has been around for a very long time. Chemistry is the branch of physical science that studies the composition, properties, energy and behavior of matter. Chemistry is said to have existed since prehistoric times. This took the form of everyday objects like pottery, cosmetics and perfumes, as well as the extraction of metals from ores. Chemistry is based on the discovery and study of elements. Some elements were known to ancient humans, but most were discovered by chemists and alchemists. Some say that chemistry began in the early Stone Age, when man created fire. Chemistry is the study of the chemical composition and properties of matter as well as 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 have no idea of ​​the wonderful, confusing and indispensable world of chemistry. Before chemical society knew about the elements, it did not know about substances like acids and metals, or the difference between gold and lead. There are many simple things that would remain unknown if chemistry were not as advanced as it is today. Chemistry is important in everyday life because everything is made up of chemicals. Chemistry is outside with the leaves changing color in the fall. Supplies used to complete household chores are made from chemicals. Chemistry is literally in everything, from the food you eat to the air you breathe. It's in your soap opera, your emotions and everything you can see or touch. Antoine Laurent Lavoisier is considered the father of modern chemistry. He had a huge impact on the way the world views chemistry today. From identification of elements to discovery...... middle of paper...... has not always been used wisely. It can be used for harmful purposes, for example carbon monoxide has always been one of the most harmful toxic gases. Carbon monoxide is a toxic, odorless and colorless gas. Some symptoms of carbon monoxide exposure are flu, headache, nausea, dizziness and disorientation. Carbon monoxide is present in many household equipment that we use daily, such as: gas heaters, tobacco smoke, generators, gas stoves, cars, buses and other vehicles. Carbon monoxide can be very harmful to humans if exposed too much. At moderate levels, it can cause angina, blindness and decreased brain function. Chemistry is present in everything 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.
