HOW DO ATOMS BEHAVE DURING A CHEMICAL REACTION?
Chemical reactions occur when bonds between atoms break and new bonds form, creating a new arrangement of atoms and at least one new substance. Observable changes, such as temperature fluctuations, color changes, gas formation, new solids, and odors, accompany these reactions.
Conservation in Chemical Reactions
Besides energy, mass is also conserved during chemical reactions. Lavoisier's experiment disproving the "phlogiston theory" led to the development of the "law of conservation of mass," which states that matter cannot be created or destroyed in a chemical reaction. Balanced chemical equations represent this law.
Energy and Reactions
Energy is required to initiate reactions. Simply mixing chemicals... Continue reading "Understanding Chemical Reactions: From Atoms to Acid Rain" »
