For substances which have two ( or more ) stable crystalline forms, such as diamond and graphite for carbon, there is a kind of " chemical degeneracy ".

For example, all atoms with 6 protons in their nuclei are atoms of the chemical element carbon, and all atoms with 92 protons in their nuclei are atoms of the element uranium.

For purposes of international communication and trade, the official names of the chemical elements both ancient and more recently recognized are decided by the International Union of Pure and Applied Chemistry ( IUPAC ), which has decided on a sort of international English language, drawing on traditional English names even when an element's chemical symbol is based on a Latin or other traditional word, for example adopting " gold " rather than " aurum " as the name for the 79th element ( Au ).

For example, sodium has the chemical symbol ' Na ' after the Latin natrium.

For pure chemical elements, polymorphism is known as allotropy.

For instance, it defined chemical engineering to be a " science of itself, the basis of which is ... unit operations " in a 1922 report ; and with which principle, it had published a list of academic institutions which offered " satisfactory " chemical engineering courses.

For example, in the 1919 book Chemistry of Human Life physician George W. Carey states that, " Health depends on a proper amount of iron phosphate Fe < sub > 3 </ sub >( PO < sub > 4 </ sub >)< sub > 2 </ sub > in the blood, for the molecules of this salt have chemical affinity for oxygen and carry it to all parts of the organism.

For comparison, treating of cotton during a typical U. S. growing season requires the same amount of chemical as roughly 1, 700 homes.

For iron rust to occur the metal has to be in contact with oxygen and water, although chemical reactions for this process are relatively complex and not all of them are completely understood, it is believed the causes are the following:

For example, the chemical compound n-hexane has the structural formula, which shows that it has 6 carbon atoms arranged in a chain, and 14 hydrogen atoms.

For over 40 years, the FBI crime lab in Quantico believed lead in bullets had unique chemical signatures.

For example, snails may be dealt with through the use of a chemical pesticide, an organic pesticide, hand-picking, barriers, or simply growing snail-resistant plants.

For example ruby and sapphire have the same chemical composition ( both are corundum ) but exhibit different colors.

For example, diamonds, ruby, sapphires and emeralds have been manufactured in labs to possess identical chemical and physical characteristics to the naturally occurring variety.

For example, the stability and low energy of the electron cloud state in helium accounts for the element's chemical inertness, and also the lack of interaction of helium atoms with each other, producing the lowest melting and boiling points of all the elements.

For example, the metals cobalt and nickel had been assigned the atomic numbers 27 and 28, respectively, based on their known chemical and physical properties, even though they have nearly the same atomic masses.

For example, there was a so-called " element " that was even given the chemical name of " didymium ".

For example, semantic externalists maintain that the word " water " referred to the substance whose chemical composition is H < sub > 2 </ sub > O even before scientists had discovered that chemical composition.

For example, if one tried to demonstrate it using the hydrocarbons decane ( chemical formula C < sub > 10 </ sub > H < sub > 22 </ sub >) and undecane ( C < sub > 11 </ sub > H < sub > 24 </ sub >), one would find that 100 grams of carbon could react with 18. 46 grams of hydrogen to produce decane or with 18. 31 grams of hydrogen to produce undecane, for a ratio of hydrogen masses of 121: 120, which is hardly a ratio of " small " whole numbers.

For example, the olivine group is described by the variable formula ( Mg, Fe )< sub > 2 </ sub > SiO < sub > 4 </ sub >, which is a solid solution of two end-member species, magnesium-rich forsterite and iron-rich fayalite, which are described by a fixed chemical formula.

For, if so, the path leads through a complex process of parliamentary diplomacy which adds still another dimension to the problem.

For, in the process of decanting, the bottle is only tilted once instead of several or more times at the table: hence, a minimum of the undesirable mixture of wine and dregs.

For some such computational process, the algorithm must be rigorously defined: specified in the way it applies in all possible circumstances that could arise.

For example, the positrons produced in natural radioactive decay quickly annihilate themselves with electrons, producing pairs of gamma rays, a process exploited in positron emission tomography.

For a simple substance, during an adiabatic process in which the volume increases, the internal energy of the working substance must decrease

For this reason, knowing whether a file uses premultiplied or straight alpha is essential to correctly process or composite it.

For Joseph and his supports of Imperial reform, besides encouraging any first buddings of pan-national pride that would unite his multi-lingual and ethnic subjects under one common language ; they also hoped to save a considerable amount of money in the process.

For a steady state process, the rate at which mass enters the volume is equal to the rate at which it leaves the volume.

For the U. S. Government's scientific enterprise, a significant impact of NAPAP were lessons learned in the assessment process and in environmental research management to a relatively large group of scientists, program managers and the public.

For most of human history, pearls were the ultimate precious beads of natural origin because of their rarity, although the pearl-culturing process has now made them far more common.

For these reasons, a setup of bioleaching must be carefully planned, since the process can lead to a biosafety failure.

For example, if in a search task the reaction times vary proportionally with the number of elements, then it is evident that this cognitive process of searching involves serial instead of parallel processing.

For example, in the Haber process, finely divided iron serves as a catalyst for the synthesis of ammonia from nitrogen and hydrogen.

For alkenes and similar double bonded molecules, the same prioritizing process is followed for the substituents.

For example, recently several bird classified as threatened with extinction appeared in the legal wild bird trade because the CITES process never considered their status.

For 2D vector animations, the rendering process is the key frame illustration process, while tweened frames are rendered as needed.

* Poor integration: For many companies, integrations are piecemeal initiatives that address a glaring need: improving a particular client-facing process or two or automating a favored sales or client support channel.

For hundreds of years, the chocolate-making process remained unchanged.

For example, while in a conversion to Judaism a convert must accept basic Jewish principles of faith, and renounce all other religions, the process is more like a form of adoption, or changing national citizenship ( i. e. becoming a formal member of the people, or tribe ), with the convert becoming a " child of Abraham and Sarah.

For a time-dependent process of heating of the calorimetric material, defined by a continuous joint progression of and, starting at time and ending at time, there can be calculated an accumulated quantity of heat delivered,.

For English Dominican mystics, the mystical experience was not expressed just in one moment of the full knowledge of God, but in the journey of, or process of, faith.

For electric utilities, it is the first process in the delivery of electricity to consumers.
