A balanced chemical equation often may be derived from a qualitative description of some chemical reaction by a fairly simple approach known as balancing by inspection. Consider as an example the decomposition of water to yield molecular hydrogen and oxygen. WebDec 9, 2024 · A B + C. However, it is useful in kinetics to distinguish this from a net reaction, which is written either with two one-sided arrows or an "equal" sign. A ↽ − − ⇀ B + C. A = B + C. When one combines a composite mechanism to obtain a net reaction, one should not use the simple arrow in the resulting equation.
