In IUPAC nomenclature, organic compounds that have a – C ≡ N functional group are called nitriles.

In inorganic chemistry, salts containing the C ≡ N < sup >−</ sup > ion are referred to as cyanides.

Then, once this claim ( expressed in the previous sentence ) is proved, it will suffice to prove " φ is either refutable or satisfiable " only for φ's belonging to the class C. Note also that if φ is provably equivalent to ψ ( i. e., ( φ ≡ ψ ) is provable ), then it is indeed the case that " ψ is either refutable or satisfiable " → " φ is either refutable or satisfiable " ( the soundness theorem is needed to show this ).

Other more exotic carbon – oxygen anions exist, such as acetylenedicarboxylate ( O < sub > 2 </ sub > C – C ≡ C – CO < sub > 2 </ sub >< sup > 2 −</ sup >), mellitate ( C < sub > 12 </ sub > O < sub > 9 </ sub >< sup > 6 −</ sup >), squarate ( C < sub > 4 </ sub > O < sub > 4 </ sub >< sup > 2 −</ sup >), and rhodizonate ( C < sub > 6 </ sub > O < sub > 6 </ sub >< sup > 2 −</ sup >).

The simplest acyclic alkenes, with only one double bond and no other functional groups, form an homologous series of hydrocarbons with the general formula C < sub > n </ sub > H < sub > 2n </ sub >.

This double bond is stronger than a single covalent bond ( 611 kJ / mol for C = C vs. 347 kJ / mol for C — C ) and also shorter with an average bond length of 1. 33 Angstroms ( 133 pm ).

This bond lies outside the main C — C axis, with half of the bond on one side and half on the other.

At room temperature and pressure, barium has a body-centered cubic structure, with a barium – barium distance of 503 picometers, expanding with heating at a rate of approximately 1. 8 /° C.

The distance from the center C to either focus is f

If an ideal thermally conductive blackbody was the same distance from the Sun as the Earth is, it would have a temperature of about 5. 3 ° C.

So the parameters are: a — distance from center C to either vertex b — length of a perpendicular segment from each vertex to the asymptotes c — distance from center C to either Focus point, F < sub > 1 </ sub > and F < sub > 2 </ sub >, and θ — angle formed by each asymptote with the transverse axis.

For any point P on the minor arc BC of the circumcircle of an equilateral triangle ABC, with distances q and t from B and C respectively, and with the intersection of PA and BC being at a distance y from point P, we have that y is half the harmonic mean of q and t.

That is, taking norms as distances, the distance from point A through B to C is never shorter than going directly from A to C, or the shortest distance between any two points is a straight line.

The first white dwarf discovered was in the triple star system of 40 Eridani, which contains the relatively bright main sequence star 40 Eridani A, orbited at a distance by the closer binary system of the white dwarf 40 Eridani B and the main sequence red dwarf 40 Eridani C.

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.

Ordinary pressure cookers are generally unsuitable for pressure frying, because they are typically designed for a maximum temperature around 121 ° C ( 250 ° F ) whereas oil can reach temperatures well in excess of 160 ° C ( 320 ° F ) which may damage the gasket in an ordinary pressure cooker causing it to fail.

On that day, the temperature maxed out at 121 ° F / 49. 4 ° C.

Judging from hyperthermophile organisms, the temperature limit is at about 120 ° C ( the recently discovered Strain 121 can reproduce at 121 ° C ), which limits the possible depth to 4-4. 5 km below the continental crust, and 7 or 7. 5 km below the ocean floor.

The major difference is the size of the chalcogenide, C – S bond lengths being around 180 picometers in length.

The Secretary of the Treasury, upon the concurrence of the Secretary of State, is authorized and directed, out of the sum covered into the Yugoslav Claims Fund pursuant to subsection ( B ) of this section, after completing the payments of such funds pursuant to subsection ( C ) of this Section, to make payment of the balance of any sum remaining in such fund to the Government of the Federal People's Republic of Yugoslavia to the extent required under Article 1 ( C ) of the Yugoslav Claims Agreement of 1948.

If A is the major axis of an ellipsoid and B and C are the other two axes, the radius of curvature in the ab plane at the end of the axis Af, and the difference in pressure along the A and B axes is Af.

Since the circulating thyroid hormones are the amino acids thyroxine and tri-iodothyronine ( cf. Section C ), it is clear that some mechanism must exist in the thyroid gland for their release from proteins before secretion.

( C ) if Af is the operator induced on Af by T, then the minimal polynomial for Af is Af.

Consider a simple, closed, plane curve C which is a real-analytic image of the unit circle, and which is given by Af.

On C, from the point P at Af to the point Q at Af, we construct the chord, and upon the chord as a side erect a square in such a way that as S approaches zero the square is inside C.

If the vertex is at Af, and if the interior of C is on the left as one moves in the direction of increasing t, then every such corner can be found from the curve obtained by rotating C clockwise through 90-degrees about the vertex.

With the vertex at Af in the C-plane we assume that Af is the parametric location on C of an ordinary intersection Q between C and Af.

But Af is just the curve Af translated without rotation through a small arc, for Af is always obtained by rotating C through exactly 90-degrees.

Thus if E is sufficiently small, there can be only one intersection of C and Af near Q, for if there were more than one intersection for every E then the difference between C and Af near Q would not be a monotone function.
