What is the chemical formula for hydroxide, carbon dioxide, methane, zinc oxide, nitrate, and polyatomic ions such as hydrogen phosphite and hydrogen sulfate?
What is the coefficient of H2O when the following equation is properly balanced with smallest set of whole numbers?
The isoelectric point (pI) of a peptide is the pH at which the peptide does not migrate in an electric field. Since the peptide is zwitterionic, there are the same number of positive charges as negative charges on the peptide population.
