When a reversible reaction is occurring in both directions at the same rate, it is called a dynamic equilibrium. In this state, the concentration of reactants and products remains constant over time, indicating that the forward and reverse reactions are happening at an equal rate.
This phenomenon is probable possible for hydrogen, boron, nitrogen, carbon, oxygen and lithium isotopes. Repeated cycles of chemical reactions can lead to some fractionation by ion exchange or other processes.
Elements in the same group have similar chemical properties because they have the same number of valence electrons that are used in chemical reactions.
Identical nuclei refer to two or more nuclei that have the same number of protons and neutrons. They have the same mass number and atomic number, indicating that they belong to the same element. Identical nuclei have the same nuclear properties and behave similarly in nuclear reactions and processes.
It is an isotope that occurs in nature, and is not manmade. Isotopes, by the way, are atoms that have the same number of protons, but different number of neutrons. The atomic number is the same, but atomic weight (or mass) is different. For instance, Carbon can be Carbon 10, 11, 12, or 14. They are all carbon.
The processes that are occurring in the present are the same processes that occurred in the past.
Uniformitarianism
The same evolutionary processes, natural selection, genetic drift, gene flow and simple mutation, occurred before humans evolved and are still occurring today.

This odd-sounding dictum is a summary of Scottish geologist Charles Lyell's idea of uniformatarianism, the idea that geologic processes that are currently occurring are the same processes that occurred in the past. In short, the historical and observable geologic events that are occurring are the 'key' to unlocking the history of the geologic events that have occurred and were recorded in the rock record.

Chemical reactions in cells are faster than the same reactions outside cells.
This phenomenon is probable possible for hydrogen, boron, nitrogen, carbon, oxygen and lithium isotopes. Repeated cycles of chemical reactions can lead to some fractionation by ion exchange or other processes.
opposing
Not mutually the same, different, opposing.
The act of grinding the food is not chemical change, as the same molacules are present in the same form, but there are many chemical reactions in the mouth (such as the breakdown of long chain carbohydrates), and other processes which aid digestion (mixture with mucus)
Occurring at the same time.
