... The exact size of the cubit that Noah would have used is difficult to determine. The size of a cubit was defined as the distance between a man’s elbow and the tips of his fingers. Different ancient civilizations standardized the cubit at different lengths (between 17 and 25 inches), so for now we’ll ...

... and the pKa of water is 15.7. Because hydrogen chloride is the stronger acid, it will donate a proton to water. Water, therefore, is a base in this reaction. When we compare the pKa values of the two reactants of the second reaction, we see that the pKa of ammonia is 36 and the pKa of water is 15.7. ...

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.
