Final answer:
A complete reaction is one where all reactants are converted into products with no residual reactants. An incomplete reaction is one where some reactants are not fully converted into products. Chemical equilibrium is important for maintaining a dynamic balance between forward and reverse reactions, ensuring a stable state.
Step-by-step explanation:
A complete reaction is a type of chemical reaction where all reactants are converted into products, leaving no residual reactants. For example, when sodium chloride (NaCl) reacts with silver nitrate (AgNO3), it forms sodium nitrate (NaNO3) and silver chloride (AgCl), with no excess NaCl or AgNO3 remaining.
An incomplete reaction is a type of chemical reaction where some of the reactants are not fully converted into products. This can happen when there isn't enough of one of the reactants, or under certain conditions where the reaction does not proceed to completion.
The importance of chemical equilibrium is that it allows for the dynamic balance between the forward and reverse reactions in a chemical system. It ensures that the concentrations of reactants and products remain constant over time, allowing for a stable state.
Equilibrium is vital in various chemical processes, such as industrial reactions, biological systems, and everyday chemical reactions.
