![]() Photosynthesis is one of the fundamental chemical reactions in plants and provides us with food. Plants: The main reason we can obtain food from plants is chemistry. By learning chemistry, we can appreciate the chemical properties of oils, salts, vitamins, minerals, and nutrients, etc., and use them wisely. are based on the chemical properties of substances. – Linus Pauling"Ĭhemistry is so intertwined with our lives that we often cannot distinguish it.įood industry: Fermentation, baking, boiling, sauteing, preserving, etc. They are missing an important source of happiness. "I feel sorry for people who don’t understand anything about chemistry. In our online chemistry calculators section, you will find scientific calculators that make such chemistry calculations easier. Their studies brought out many valuable equations, principles, and calculations that revealed the secrets of our daily life. Some of such prominent scientists that dedicated their lives to the study of chemistry include:Īll these great scientists invented and discovered astonishing facts related to chemistry. Later, numerous scientists made their contributions to reveal the mysteries of chemistry. have their base in the magic of chemistry.ĭo you know who is the father of chemistry? Antoine Lavoisier, the famous French scientist, is considered the Father of Modern Chemistry. Precipitation and rainfall, ice floating on lakes, rain cycles, colors of leaves and flowers, etc. ![]() Chemistry helps us to marvel at the beauty of nature and its miracles.We can identify potentially dangerous chemicals and combinations and stay away from them. Knowing the basics of chemistry helps us to stay safe.Those who study chemistry are in intense demand in academia, research, and scientific fields. Chemistry opens doors for brighter career opportunities.We understand many high-level phenomena including global warming, pollution, desalination of ocean water, recycling e-waste, benefits of switching to organic farming, etc.We can make safer choices about the chemical products we deal with in our daily life, such as medicines, cosmetics, and home cleaning products.And many more.Ī knowledge of chemistry principles helps us in many ways: Digestion, respiration, metabolism, photosynthesis, energy production, pharmaceuticals, fuels, desalination of water. Chemistry principles guide our daily life applications. This relationship enables the determination of all values, as long as at least one is known.Chemistry dictates everything in our life. Using the above equations, it is also possible for a relationship to be derived between t 1/2, τ, and λ. Derivation of the Relationship Between Half-Life Constants This means that the fossil is 11,460 years old. If an archaeologist found a fossil sample that contained 25% carbon-14 in comparison to a living sample, the time of the fossil sample's death could be determined by rearranging equation 1, since N t, N 0, and t 1/2 are known. N t is the remaining quantity after time, t The carbon-14 undergoes radioactive decay once the plant or animal dies, and measuring the amount of carbon-14 in a sample conveys information about when the plant or animal died.īelow are shown three equivalent formulas describing exponential decay: It is incorporated into plants through photosynthesis, and then into animals when they consume plants. The process of carbon-14 dating was developed by William Libby, and is based on the fact that carbon-14 is constantly being made in the atmosphere. The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to around 50,000 years ago. One of the most well-known applications of half-life is carbon-14 dating. The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not. Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value.
