The red back (or redback or red backed) salamander (Plethodon cinereus) is a small, hardy woodland salamander.

This is actually a picture of a salamander.

I had to get a molar extracted.

The upper third premolar and lower molar are adapted as carnassial teeth, suited to tearing and cutting flesh.

The gecko's a really great example of nanotechnology in nature.

The Chinese giant salamander ( Andrias davidianus ) is the largest salamander and largest amphibian in the world, reaching a length of , although it rarely if ever reaches that size today.

The gecko has a billion of these 200 nanometer sized split ends.

It is also occasionally called the human fish by locals because of its skin color, similar to that of white people (translated literally from and ), as well as cave salamander or white salamander.

The final set of molars last for about twenty years.

Full results from these determinations were expected in late 2010.

The Musteloidea in turn consists of the Mustelidae (mustelids weasels), Procyonidae (procyonids raccoons), Mephitidae (skunks) and Ailurus (red panda).

The Corsican fire salamander (Salamandra corsica) is a species of salamander in the Salamandridae family found only on the island of Corsica as an endemic species.

It can grow to in length with S. i. infraimmaculata being the largest subspecies.

The albite anorthite molar ratio ranges from 90 10 to 70 30.

The molars or molar teeth are the most posterior and most complicated kind of tooth in most mammals.

The Ezo salamander or Hokkaido salamander ( Hynobius retardatus ) is a species of salamander in the Hynobiidae family, endemic to Japan.

And I thought molecular weight sounded much less nerdy than molar mass.

The mass per mole of a substance is called its molar mass.

Each vibrational mode will contribute formula_64 to the total molar heat capacity, however.

In case of an ideal gas, we can derive that formula_19, i.e.

We took some hairs from a molting gecko put three rolls of them on here, and then made this Band Aid.

S. a. aurorae , the golden alpine salamander, is classified as being Critically Endangered on the IUCN Red List 2002.

This is most often accomplished by expressing the property in relation to a unit of mass.

When the molar mass is greater than 1000 g mol, it is rarely appropriate to use more than one decimal place.

Light blue curves supercritical isotherms van der Waals model Real gases are often modeled by taking into account their molar weight and molar volume formula_1Where P is the pressure, T is the temperature, R the ideal gas constant, and Vm the molar volume.

Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.

In this predator prey pair, an evolutionary arms race has produced high levels of toxin in the newt and correspondingly high levels of toxin resistance in the snake.

In chemistry, heat capacity is often specified relative to one mole, the unit of amount of substance, and is called the molar heat capacity.

Mathematically, the pressure of a mixture of non reactive gases can be defined as the summation formula_1 or formula_2where formula_3 represent the partial pressure of each component.

Methane has been detected in the Martian atmosphere with a mole fraction of about 30 ppb it occurs in extended plumes, and the profiles imply that the methane was released from discrete regions.

the number of helium atoms per molecule of gas, is in the upper troposphere, which corresponds to a mass fraction .

The normal antithrombin concentration in human blood plasma is high at approximately 0.12 mg ml, which is equivalent to a molar concentration of 2.3 μM.

Prunus amygdalus , Amygdalus communis , Amygdalus dulcis ) (or badam in Indian English, from ) is a species of tree native to the Middle East and South Asia.

Methane molecules account for 2.3 of the atmosphere by molar fraction below the methane cloud deck at the pressure level of 1.3 bar (130 kPa) this represents about 20 to 30 times the carbon abundance found in the Sun.

Noting the relationships between Boltzmann's constant and the Universal gas constant, and observing that the number of molecules can be expressed in terms of Avogadro's number and the molar mass, the reduced number density formula_93 can be expressed in terms of the molar volume as formula_103The shape parameter formula_104 appearing in the Attraction term and the term formula_105 are given by formula_106 (and is hence also equal to 1 for spherical molecules).

Van der Waals equation of state The Van der Waals equation of state may be written formula_24where formula_25 is molar volume.

Corollaries of these considerations for solids (volume specific heat capacity) Since the bulk density of a solid chemical element is strongly related to its molar mass (usually about 3 R per mole, as noted above), there exists a noticeable inverse correlation between a solid s density and its specific heat capacity on a per mass basis.

The constants appearing in the above equation are available in following tablewhen P is in KPa, v is in formula_24, T is in K and R 8.314formula_25 Benedict Webb Rubin model The BWR equation, sometimes referred to as the BWRS equation,formula_26where d is the molar density and where a, b, c, A, B, C, α, and γ are empirical constants.

Applications Solubility is of fundamental importance in a large number of scientific disciplines and practical applications, ranging from ore processing, to the use of medicines, and the transport of pollutants.

In the absence of stronger inter species attractions between like like or like unlike molecules, the vapor pressure follows Raoult's Law, which states that the partial pressure of each component is the product of the vapor pressure of the pure component and its mole fraction in the mixture.

Mathematically, Raoult's law for a single component in an ideal solution is stated as formula_1,where formula_2 is the partial vapor pressure of the component formula_3 in the gaseous mixture (above the solution), formula_4 is the vapor pressure of the pure component formula_3, and formula_6 is the mole fraction of the component formula_3 in the mixture (in the solution).

The substance specific constants formula_26 and formula_27 can be calculated from the critical properties formula_28 and formula_29 (noting that formula_29 is the molar volume at the critical point) as formula_31 formula_32Also written as formula_33 formula_34Proposed in 1873, the van der Waals equation of state was one of the first to perform markedly better than the ideal gas law.

The change in pressure with height, therefore can be equated to the density with this hydrostatic equation formula_1where gn is the standard gravity ρ is the density z is the altitude p is the pressure R is the gas constant T is the thermodynamic (absolute) temperature m is the molar massSince temperature in principle also depends on altitude, one needs a second equation to determine the pressure as a function of height, as discussed in the next section.
