In the chemical equation, the single arrow represented the chemical reaction between the reagents, and the equal sign represented the equality between the product and the reagent. Therefore, a single arrow was usually used to represent a chemical reaction. For example: 2H2 + O2 → 2H2O(reaction) In this equation, the single arrow represented the chemical reaction between two hydrogen atoms and two oxygen atoms, and the equal sign represented the equality between two hydrogen atoms and two oxygen atoms. Of course, in some cases, if the reagent and the product contain the same or different elements, or the elemental composition between the reagent and the product is different, it may be necessary to use double arrows to indicate the reaction and formation.
