Air is a mixture of gases primarily composed of nitrogen (N2) and oxygen (O2). The molecular equation for air can be represented as: N2 (approximately 78%) + O2 (approximately 21%) + trace amounts of other gases such as argon, carbon dioxide, and water vapor.
Air does not have an equation.
You may mean formula.
Air does not have a formula either as it is a mixture.
The subscript denotes how much of that atom is in the molecule.
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
The isoelectric point (pI) is the pH at which a molecule has no net charge. To find pI from the Henderson-Hasselbalch equation, set the net charge of the molecule equal to zero and solve for pH. This equation is derived by considering the acidic and basic dissociation constants of the molecule to calculate the pH at which the net charge is zero.
The equation is: H2O------>H+ + OH-
A coefficient.
