Final answer:
Chemistry is a fundamental science that affects everyday life, involving activities like making coffee and using various products. It has evolved from alchemy into a modern science with significant contributions from historical figures like Dalton and Avogadro.
Step-by-step explanation:
One thing that I previously knew about chemistry is that it is a central science intertwined with many aspects of our daily lives and various scientific disciplines. For instance, activities such as making coffee, cooking eggs, and toasting bread involve chemical reactions and principles. Furthermore, the products we use regularly, like soap and shampoo, and the gasoline that powers our cars are all complex mixtures of chemicals. The study of chemistry provides vital insights into understanding the composition and behavior of these substances.
From a historical perspective, chemistry evolved from alchemy after the Middle Ages, transitioning towards a science with a focus on collective knowledge and open discovery. Pioneers like John Dalton and Amedeo Avogadro contributed significantly to our understanding of atomic theory and the mole concept, which are foundational to the field of chemistry.
