WebJul 29, 2024 · A chemical compound is a substance that always contains the same atoms in the same ratio. In chemical reactions, atoms from one or more compounds or elements redistribute or rearrange in relation to other atoms to form one or more new compounds. Atoms themselves do not undergo a change of identity in chemical reactions. WebConservation of atoms - During a chemical reaction, the number of atoms of each element is conserved. For example, let's revisit the reaction between methane and oxygen: CH 4 + 2O 2 CO 2 + 2H 2 O. You can add up the number of atoms of each element on each side of the arrow as follows: # atoms in reactants # atoms in products:
