Writing and Balancing Chemical Equations – Chemistry
Write and balance chemical equations in molecular, total ionic, and net ionic formats. The preceding chapter introduced the use of element syols to represent individual atoms. When atoms gain or lose electrons to yield ions, or coine with other atoms to form molecules, their syols are modified or coined to generate chemical formulas that appropriately represent these species.
