In many chemical reactions of two or more compounds, ions are present in the solution that do not participate in the reaction. These ions, known as spectator ions, can be removed from the chemical equation describing the reaction. A chemical equation that has the spectator ions removed is known as a net ionic equation. Reactions between ionic compounds often result in the precipitation of an insoluble compound. Spectator ions and precipitation products of a chemical reaction can be predicted by...

Ethalpy Change of a Chemical Reaction, Sample calculations for
Run 2 B, all questions, please help me, thank you very much
A chemical reaction involves breaking, making, or changing chemical bonds. These alterations in bonding lead to a change in enthalpy, AHo, between the products and reactants. This enthalpy change takes into account the change in intermal energy in the system and the work done by the system on its surroundings during the reaction. If the reaction occurs at a...
