If the adsorbate has a unity sticking coefficient, so that every molecule which reaches the surface sticks to it without re-evaporating, then the monolayer time is very roughly:

If we call v < sub > mon </ sub > the STP volume of adsorbate required to form a monolayer on the adsorbent ( per gram of adsorbent ), and we obtain an expression for a straight line:

If we assume that the number of sites is just the whole area of the solid divided into the cross section of the adsorbate molecules, we can easily calculate the surface area of the adsorbent.

If the adsorbate molecule in the precursor state is in close proximity to an adsorbate molecule which has already formed on the surface, it has a sticking probability reflected by the size of the S < sub > E </ sub > constant and will either be adsorbed from the precursor state at a rate of k < sub > EC </ sub > or will desorb into the gaseous phase at a rate of k < sub > ES </ sub >.

If an antibody is developed to stabilize a molecule that's similar to an unstable intermediate of another ( potentially unrelated ) reaction, the developed antibody will enzymatically bind to and stabilize the intermediate state, thus catalyzing the reaction.

If a diatomic molecule consists of two atoms of the same element, such as H < sub > 2 </ sub > and O < sub > 2 </ sub >, then it is said to be homonuclear, but otherwise it is heteronuclear.

If the ether is part of a more complex molecule, it is described as an alkoxy substituent, so-OCH < sub > 3 </ sub > would be considered a " methoxy -" group.

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 the molecule is symmetrical, e. g. N < sub > 2 </ sub >, the band is not observed in the IR spectrum, but only in the Raman spectrum.

If inversion through the center of symmetry in a molecule results in the same phases for the molecular orbital, then the MO is said to have gerade, g, symmetry.

If inversion through the center of symmetry in a molecule results in a phase change for the molecular orbital, then the MO is said to have ungerade, u, symmetry.

* If the molecule has some symmetry, the degenerate atomic orbitals ( with the same atomic energy ) are grouped in linear combinations ( called symmetry-adapted atomic orbitals ( SO )), which belong to the representation of the symmetry group, so the wave functions that describe the group are known as symmetry-adapted linear combinations ( SALC ).

If the carbonyl is at position 1 ( that is, n or m is zero ), the molecule begins with an formyl group H ( C = O )-, and is technically an aldehyde.

If the molecule can be rotated in space so that the directions of those four groups match those of the analog groups in-glyceraldehyde's C2, then the isomer receives the '-' prefix.

If the biologically active molecule chosen for PET is FDG, an analogue of glucose, the concentrations of tracer imaged then give tissue metabolic activity, in terms of regional glucose uptake.

If the struck molecule is DNA it can show a spontaneous mutation.

If the potential energy is set to zero at infinite distance from the atomic nucleus or molecule, the usual convention, then bound electron states have negative potential energy.

If an atom, ion, or molecule is at the lowest possible energy level, it and its electrons are said to be in the ground state.

If the final vibrational state of the molecule is more energetic than the initial state, then the emitted photon will be shifted to a lower frequency in order for the total energy of the system to remain balanced.

If we define the exobase as the height at which upward traveling molecules experience one collision on average, then at this position the mean free path of a molecule is equal to one pressure scale height.

If some force is acting on the elastic cantilever ( for example because some molecule is being stretched between the surface and the tip ), this will deflect upward ( repulsive force ) or downward ( attractive force ).

If the union is between atoms or groups of the same molecule, the reaction is termed intramolecular condensation, and in many cases leads to ring formation.

If an inducer molecule is present, it binds to the repressor and changes its conformation so that it is unable to bind to the operator.

If the TCR is specific for that antigen, it binds to the complex of the Class I MHC molecule and the antigen and the T cell destroys the cell.

* Continuity: If a certain mass of fluid enters a volume, it must either exit the volume or change the mass inside the volume.

If the liquid and vapor are not evenly distributed across the superficial tower area as it enters the packed bed, the liquid to vapor ratio will not be correct in the packed bed and the required separation will not be achieved.

If the signals are sent to the reticular formation and thalamus, the sensation of pain enters consciousness in a dull poorly localized manner.

The passers-by spit in his face, and sometimes beat him … unmercifully … If a Jew enters a shop for anything, he is forbidden to inspect the goods … Should his hand incautiously touch the goods, he must take them at any price the seller chooses to ask for them ...

If the beam enters the sample perpendicular to the surface, then the activated region is uniform about the axis of the beam and a certain number of electrons " escape " from within the sample.

If the cloud is sufficiently large and the droplets within are spaced far enough apart, a percentage of the light that enters the cloud is not reflected back out but is absorbed giving the cloud a darker look.

If the player loses, it means that a normal koatari has been hit and the machine enters into jitan mode.

* Square ball: If, at the moment the ball enters " the square " ( the small rectangle surrounding the goal ), there is already an attacking player inside, a free out is awarded

If elected, it would mark the first occasion that an outspoken non-religious party enters Urk's town council.

If you told someone who purports to be a sage of Israel that the Deity sends an angel who enters a woman's womb and there forms an embryo, he would think this a miracle and accept it as a mark of the majesty and power of the Deity, despite the fact that he believes an angel to be a body of fire one third the size of the entire world.

Statutory Burglary is defined as: If any person in the nighttime enters without breaking, or in the daytime breaks and enters or enters and conceals himself in a dwelling house or an adjoining, occupied outhouse, or, in the nighttime enters without breaking or at any time breaks and enters or enters and conceals himself in any office, shop, manufactured home, storehouse, warehouse, banking house, church or other house, or any ship, vessel or river craft, or any railroad car, or any automobile, truck, or trailer, if such automobile, truck or trailer is used as a dwelling or place of human habitation, with intent to commit murder, rape, robbery or arson in violation of Virginia State code section 18. 2-77, 18. 2-79, or 18. 2-80, shall be deemed guilty of statutory burglary, which offense shall be a class 3 felony.
