👉 Reactions are a type of chemical reaction in which one substance reacts with another to produce more substances. This can be represented as: \[ A + B \rightarrow C \] Where, A is the reactant, B is the product, and C is the byproduct. In other words, when two substances combine to form a new compound, it means that both substances have reacted in some way with each other. Reactions are crucial for understanding how chemical reactions occur and how they can be controlled
