A chemical reaction can be shown by the balanced chemical reaction if its reactant and product side has the same amount of each chemical element. For example, 2 H 2 + O 2 → 2 H 2 O is a balanced chemical reaction. The reason is that there are four hydrogens on the reactant and product side and two oxygen on the reactant and product side.
Precipitation: A precipitate is a solid that forms in solution. Precipitation may occur when a solute surpasses its solubility in a particular solvent. It also occurs when an insoluble compound forms due to a chemical reaction. One type of reaction that may cause precipitation is a double replacement ionic reaction where two soluble ionic salt ...
