Question

Chemical equations need to be balanced not only in terms ofthe number of atoms, but also by the charge. In onther words,just as the same number of atoms should appear before and after thearrow of an equation, so should the same charge. Thake thisinto account to balance fhte following chemical equations: Sn2+ + Ag ---> Sn + Ag+ ___________________ I don't see how you balance the charge.

Explanation / Answer

Typically in chemistry, they consider electrons freelyavailable for chemical reactions, as they will likely be pulled offof other molecules in order for a reaction to proceedforward. If you arbitrarily add electrons on one side of the equationor the other, you can balance it out without affecting the molarconcentration.
