Alcohol Synthesis by Electrophilic Hydration
... The reversibility of alkene protonation leads to alkene equilibration. Protonation-deprotonation reactions may interconvert related alkenes and produce an equilibrium mixture of isomers. Under these conditions, a reaction is said to be under thermodynamic control. ...

Chemical Equations and Reactions
... To complete this chemical equation, we must account for the law of conservation of mass. The amounts of reactants and products need to be adjusted so that the numbers and types of atoms are the same on both sides of the equation. This process is called balancing an equation and is done by insertin ...
