: If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established.

Humphry Davy, an English chemist was among the first to expound on the chemical basis of soil fertility and wrote in 1813: “ If land be unproductive, and a system of ameliorating it is to be attempted, the sure method of obtaining the object is to determine the cause of the sterility, which must necessarily depend upon some defect in the constitution of the soil, which may be easily discovered by chemical analysis .” His ideas were not immediately accepted.

If the system is at equilibrium, then the chemical potential of the component i must be the same in the liquid solution and in the vapor above it.

If a candidate receives less than a two-thirds majority, the cardinals send up black smoke — created by burning the ballots along with wet straw and chemical additives — it means that no successful election has yet occurred.

If the patient is stable, adenosine may be administered first, as the medicine performs a sort of " chemical cardioversion " and may stabilize the heart and let it resume normal function on its own without using electricity.

If the process uses chemical energy, such as from adenosine triphosphate ( ATP ), it is termed primary active transport.

If breakdown occurs in the passive film due to chemical or mechanical factors, the resulting major modes of corrosion may include pitting corrosion, crevice corrosion and stress corrosion cracking.

If the chemical potential is the same in the two regions, the species will occasionally move back and forth between the two regions, but on average there is just as much movement in one direction as the other, and there is zero net migration ( this is called " diffusive equilibrium ").

If the chemical potentials of the two regions are different, more molecules will move to the lower chemical potential than the other direction.

If there is no coefficient before a chemical formula, the coefficient 1 is understood.

If the Gospel of Barnabas is seen as an attempted synthesis of elements from both Christianity and Islam, then 16th and 17th century parallels can be suggested in Morisco and anti-Trinitarian writings.

If a special catalyst is used in its synthesis it is possible to obtain the syndiotactic version of this polymer, but most industrial polystyrene produced is atactic.

If it starts from a product isolated from plants or animals and then proceeds to new compounds, the synthesis is described as a semisynthetic process.

If oxygen supply is inadequate ( hypoxia ), the mitochondria are unable to continue ATP synthesis at a rate sufficient to supply the cell with the required ATP.

If consensus is not reached, the process continues through thesis and antithesis, to gradually work towards synthesis, and building consensus.

If ergosterol synthesis is completely or partially inhibited, the fungal cell is unable to construct an intact cell membrane, and dies.

If two observations of the same terrain from very similar positions are available, aperture synthesis can be performed to provide the resolution performance which would be given by a RADAR system with dimensions equal to the separation of the two measurements.

If we try to create a synthesis of different traditions we shall destroy the special power of each and be left only with a mishmash of our own making that will be a source of confusion and doubt.

If the sulfur amino acids are not catabolized at the final products of urea or uric acid but used for the synthesis of keratin instead, the release of hydrogen sulfide is extremely reduced or avoided.

If we seek the blending of science and religion and the integration of secular knowledge with sacred wisdom, then it is not in the subject matter of these fields but rather within the personality of the individual that we hope to achieve the synthesis.

If the phases are known, the electron density can be simply obtained by Fourier synthesis.

If uncontrolled during melanoma, it results in increased melanin synthesis.

If they weren't, genome synthesis would be inefficient and infection may fail and hence natural selection may favour efficient RNA synthesis.

If, in a certain part of the range, it starts life 1 foot longer than do any of the other ( relatively large ) giants, and reaches maturity at, let us guess, 18 inches longer than the others, a quadrupling of the maturity length would result in a maximum of ( nearly ) 40 feet.

If sugars are heated so that all water of crystallisation is driven off, then caramelization starts, with the sugar undergoing thermal decomposition with the formation of carbon, and other breakdown products producing caramel.

If the shooter " hits " the point value again ( any value of the dice that sum to the point will do ; the shooter doesn't have to exactly repeat the value combination of the come-out roll ) before rolling a seven, the Pass line wins and a new round starts, usually with the dice staying with the current shooter.

If the missile starts to roll, the gyroscopic force of the disk drives the control surface into the airflow, cancelling the motion.

If the competitor starts the leap with any part of the foot past the foul line, the jump is declared a foul and no distance is recorded.

If some existing technology or company whose benefits are largely based on network effects starts to lose market share against a challenger such as a disruptive technology or open standards based competition, the benefits of network effects will reduce for the incumbent, and increase for the challenger.

If a child's top is tilted and spun rapidly, its rotation axis starts precessing rapidly about the vertical axis, so a point on the rotation axis appears to be executing a circular motion about the vertical axis.

If each player in a tournament starts with 5, 000 in chips and after 4 hours, the big blind is 10, 000 ( with a small blind of 5, 000 ), it will be very difficult for a player with only 15, 000 in chips to stay in the game.

:" If the pantheist starts with the belief that the one great reality, eternal and infinite, is God, he sees everything finite and temporal as but some part of God.

If the work done moving along a path which starts and ends in the same location is zero, then the force is said to be conservative and it is possible to define a numerical value of potential associated with every point in space.

If the demand starts at < tt > D2 </ tt >, and decreases to < tt > D1 </ tt >, the equilibrium price will decrease, and the equilibrium quantity will also decrease.

If the supply curve starts at < tt > S2 </ tt >, and shifts leftward to < tt > S1 </ tt >, the equilibrium price will increase and the equilibrium quantity will decrease as consumers move along the demand curve to the new higher price and associated lower quantity demanded.

If we suppose that each racer starts running at some constant speed ( one very fast and one very slow ), then after some finite time, Achilles will have run 100 metres, bringing him to the tortoise's starting point.

If unsuccessful, it starts the ConnectRetry timer and transitions to the " Active " state upon expiration.

If the system starts in a particular mode, vibrations in other modes do not develop.

If a system is to be built from existing system, this approach is more suitable as it starts from some existing modules.

If the medium becomes idle, the sender transmits a frame with a probability p. If the station chooses not to transmit ( the probability of this event is 1-p ), the sender waits until the next available time slot and transmits again with the same probability p. This process repeats until the frame is sent or some other sender starts transmitting.
