If the Af bond is linear then there are three reasonable positions for the hydrogen atoms: ( 1 ) The hydrogen atoms are centered and hence all lie on a sheet midway between the oxygen sheets ; ;

If the combustion takes place using air as the oxygen source, the nitrogen can be added to the equation, as and although it does not react, to show the composition of the flue gas:

If oxygen saturations are low, supplemental oxygen should be provided.

If an explosive molecule contains just enough oxygen to convert all of its carbon to carbon dioxide, all of its hydrogen to water, and all of its metal to metal oxide with no excess, the molecule is said to have a zero oxygen balance.

If buried on hot coals or ashes, the heat can kill pathogens, the dry ash can desiccate, and the earth can block oxygen and further contamination.

If water is evaporated too quickly, the membrane dries, resistance across it increases, and eventually it will crack, creating a gas " short circuit " where hydrogen and oxygen combine directly, generating heat that will damage the fuel cell.

If oxygen delivery to cells is insufficient for the demand ( hypoxia ), hydrogen will be shifted to pyruvic acid converting it to lactic acid.

If superoxide ion associated to Fe < sup > 3 +</ sup > is protonated the hemoglobin iron will remain oxidized and incapable of binding oxygen.

If un-aerated, the solution level is kept low enough that enough roots are above the solution so they get adequate oxygen.

If a hellbender ends up in an area of slowly moving water, not enough water will pass over its skin in a given time period, making it difficult to garner enough oxygen to support necessary respiratory functions.

If there is water, that means there is oxygen.

If oxygen, that means we can breathe.

If the core of the star is not too massive ( less than approximately 1. 4 solar mass, taking into account mass loss that has occurred by this time ), it may then form a white dwarf ( possibly surrounded by a planetary nebula ) as described above for less massive stars, with the difference that the white dwarf is composed chiefly of oxygen, neon, and magnesium.

If a red giant has insufficient mass to generate the core temperatures required to fuse carbon, around 1 billion K, an inert mass of carbon and oxygen will build up at its center.

If the bacteria possess catalase ( i. e., are catalase-positive ), when a small amount of bacterial isolate is added to hydrogen peroxide, bubbles of oxygen are observed.

If Theia had been a separate proto-planet, it probably would have had a different oxygen isotopic signature than Earth, as would the ejected mixed material.

If the sedimentation rate is low ( about 1 cm / kyr ), the organic carbon content is low ( about 1 % ), and oxygen is abundant, aerobic bacteria can use up all the organic matter in the sediments faster than oxygen is depleted, so lower-energy electron acceptors are not used.

If this was the case, Earth's free oxygen may have been nearly or totally depleted during a severe ice age circa 750 to 580 million years ago ( mya ).

If corrosion occurs, it occurs on the outside of the wire, not on the gas-tight contact where oxygen cannot penetrate to form oxides.

If this happens to such a degree that the patient cannot draw enough oxygen from his or her environment to maintain cellular respiration, then the victim may need supplemental oxygen.

If this is done through a pocket mask with an oxygen flow, this increases to 40 % oxygen.

If the drift error is systematic, it can be canceled with a bias circuit which can be arranged and adjusted to supply the required compensating current.

If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode ( the electrode connected to the negative terminal of the voltage supply ).

If so, these huge stars would have quickly consumed their supply of fuel and became supernovae, releasing heavy elements into the interstellar medium.

If the computer has a PFC power supply, this will increase the power efficiency as well, as the cheap switching power supplies included with LCD monitors rarely implement PFC.

If no minimum wage is in place, workers and employers will continue to adjust the quantity of labor supplied according to price until the quantity of labor demanded is equal to the quantity of labor supplied, reaching equilibrium price, where the supply and demand curves intersect.

If the demand curve shifted the marginal revenue curve would shift as well and a new equilibrium and supply " point " would be established.

If that ideal size is large enough to supply the whole market, then that market is a natural monopoly.

If you cut enemy supply lines, the only option for him will be to ensure supplies by air ... ( sic ).. at that situation the Indian Army was unlikely to confront and it had to come up to the occasion.

If a government-owned company providing an essential service ( such as the water supply ) to all citizens is privatized, its new owner ( s ) could lead to the abandoning of the social obligation to those who are less able to pay, or to regions where this service is unprofitable.

# If demand increases and supply remains unchanged, then it leads to higher equilibrium price and higher quantity

# If demand decreases and supply remains unchanged, then it leads to lower equilibrium price and lower quantity.

# If demand remains unchanged and supply increases, then it leads to lower equilibrium price and higher quantity.

# If demand remains unchanged and supply decreases, then it leads to higher equilibrium price and lower quantity.

This is because each point on the supply curve is the answer to the question " If this firm is faced with this potential price, how much output will it be able to and willing to sell?

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.

At least two assumptions are necessary for the validity of the standard model: first, that supply and demand are independent ; and second, that supply is " constrained by a fixed resource "; If these conditions do not hold, then the Marshallian model cannot be sustained.

If the collector voltage were zero, the collector current would be limited only by the light bulb resistance and the supply voltage.

If the elasticity of supply is low, more of the tax will be paid by the supplier.

If the flux in the core is purely sinusoidal, the relationship for either winding between its rms voltage E < sub > rms </ sub > of the winding, and the supply frequency f, number of turns N, core cross-sectional area a and peak magnetic flux density B is given by the universal EMF equation:

If the time period of blood supply impairment lasts more than a few minutes, the nerve cells of that area of the brain die and cause permanent neurologic damage.

If all four resistor values and the supply voltage () are known, and the resistance of the galvanometer is high enough that is negligible, the voltage across the bridge () can be found by working out the voltage from each potential divider and subtracting one from the other.

If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results.

If the demand for power exceeds the supply, generation plants and transmission equipment can shut down which, in the worst cases, can lead to a major regional blackout, such as occurred in the US Northeast blackouts of 1965, 1977, 2003, and in 1996 and 2011.

If the power supply and ground wires have significant resistance, the voltage drop across them may create noise voltage pulses in the ground wires, which are applied to other parts of the circuit, The large capacitance of the ground plane allows it to absorb the current pulses without much change in voltage,
