... Let A and B be the elements of the group. Let X be the element satisfying rule 2. i.e. XA = AX = A and also XB = BX = B. BA = BX2 A; BX2 = B = BE, where we have set X2 = E (identity) It is clear BEn = B, n being any integer. This kind of element E which does not effect any change when multiplied wit ...

... Let us carry this analogy one step further. Suppose we go on to cook our pizzas and accidentally burn one of them. Even though we theoretically have enough ingredients for three pizzas, we end up with only two. If this were a chemical reaction, the two pizzas would be our actual yield, the amount of ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
