WebJul 23, 2024 · During chemical reactions the bonds that hold molecules together break apart and form new bonds rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form without this energy the reaction cannot take place and the reactants remain as they were. WebBoth the initial and final substances are composed of atoms because all matter is composed of atoms. ... Atomic Theory explains the reason behind the law of conservation of matter; in chemical reactions, atoms just rearrange, so have same mass before and after. 5.1: The Law of Conservation of Matter is shared under a CC BY-NC-SA 4.0 license and ...
