WebSep 22, 2024 · In single-replacement reactions in which metals (or carbon or hydrogen) are expected to replace metals, first you should check the activity series to see if any reaction is anticipated. Remember that metals can only replace metals that are less active than themselves (to the right in the Table). WebHowever, when the reaction is not balanced (when both sides do not have equal number of atoms of every element) we multiply the value of the molecule/atom by a suitable number on the side where it has fewer atoms. We do this until the reaction is perfectly balanced and we are sure that the Law of Conservation of Mass is followed. shredding maple ridge shredding matrix protein powder
