Each experiment, the Fe VI) solution with an initial concentration of 0.2 mmol l−1, was prepared by adding a given quantity of solid K2FeO4 to the respective buffer solution, and the decomposition of samples was observed by determining the concentration of Fe VI) at different time intervals.
This funny conclusion is consistent with the principle of continuity, as we have just seen, but it enters into contradiction with what could be termed the 'postulate of permanence': no material body (and by that we mean a given quantity of matter) can go out of existence all of a sudden, without leaving any traces.
The target (also called the goal or the most favorable) value, i.e., (t_{j}), for an attribute can be defined as the maximum or minimum of the ratings of alternatives on that attribute or a given quantity considered by decision-makers.
Buffering capacity may be defined as the number of moles of a strong acid or base required to change the pH of a given quantity of a buffer by 1 pH unit [125, p. 123].
Why does a quantity of one commodity exchange for a given quantity of another commodity?
According to Faraday's law of electrolysis, the overall chemical change produced by any given quantity of electricity can be accounted exactly.
Following Newton's lead, he conceived of infinitesimals or differentials in terms of the limit concept, which he formulated by the assertion that one varying quantity is the limit of another if the second can approach the other more closely than by any given quantity.
The sensitivity of measurement is a measure of the change in instrument output that occurs when the quantity being measured changes by a given amount.
In contrast, the output-oriented model calculates efficiency as the percentage increase in outputs that is feasible by a given available quantity of inputs.
Because of the decrease in exchange current with increasing electrolyte concentration, the increased performance that can be obtained from given quantity of platinum by increasing temperature is reduced at constant water vapor pressure above the electrolyte.
