Comparing this yield to the observed damage produced a rule of thumb called the 5 psi lethal area rule.

The most reliable rule of thumb is that liqueurs are quite sweet and often syrupy in consistency, while liquors are not.

This rule states that " In the heterolytic addition of a polar molecule to an alkene or alkyne, the more electronegative ( nucleophilic ) atom ( or part ) of the polar molecule becomes attached to the carbon atom bearing the smaller number of hydrogen atoms.

The largest living forms are the polar bear ( Ursus maritimus ), with a body weight of up to, and the similarly sized Kodiak bear ( Ursus arctos middendorffi ), again consistent with Bergmann's rule.

He admits, " To be perfectly frank, I don't know the exact value of the polar gravity ; the planet is so oblate that the usual rule of spheres ... would not even be a good approximation ..." " Whirligig World " reports his initial calculations of the pole gravity to be 655 g ; the dust jacket of Heavy Planet reports it as 700 g. A later program created by Clement computed it as 275 g, as did a similar program written by the MIT Science Fiction Society.

In the mid-latitudes, westerly winds are the rule and their strength is at the mercy of the polar cyclone.

Although the results are consistent with recent findings of other NASA instruments onboard Chandrayaan-1 ( the Moon Mineralogy Mapper ( MP3 ) discovered water molecules in the Moon's polar regions, while water vapor was detected by NASA's Lunar Crater Observation and Sensing Satellite, or LCROSS ) this observation is not consistent with the presence of thick deposits of nearly pure water ice within a few meters of the lunar surface, but it does not rule out the presence of small (<∼ 10 cm ), discrete pieces of ice mixed in with the regolith .< ref >

The constitution praised Vincent, and it granted the executive sweeping powers to dissolve the legislature at will, to reorganize the judiciary, to appoint ten of twenty-one senators ( and to recommend the remaining eleven to the lower house ), and to rule by decree when the legislature was not in session.

These include the rule that the Dutch monarch cannot dissolve the House of Representatives more than once because of a conflict over a single political issue and that the Senate shall never block legislation for mere party politics, so that coalition governments ( all Dutch governments since the 19th century ) do not need a majority in the Senate.

In particular, he cannot rule by decree and he can only dissolve the Bundestag ( parliament ) if the Chancellor loses a motion of confidence and asks the President to do so.

The uterine eggs are large and numerous, but as a rule only one fully develops in each uterus, the embryo being nourished on the yolk of the other eggs, which more or less dissolve to form a large mass of nutrient matter.

Faced with a breakdown of parliamentary rule at a time when the economic situation demanded action, Brüning asked von Hindenburg to dissolve parliament and call for new elections.

The government would often dissolve assemblies, arrest elected politicians and impose President ’ s rule.

Some non-benzene-based compounds called heteroarenes, which follow Hückel's rule, are also aromatic compounds.

Since these compounds tend to be more reactive than compounds that obey their rule, electron counting is an important tool for identifying the reactivity of molecules.

As a very general rule, primary explosives are considered to be those compounds that are more sensitive than PETN.

The " C-H bond-only " rule also leads to somewhat arbitrary divisions in sets of carbon-fluorine compounds, as, for example, Teflon is considered by this rule " inorganic " but Tefzel organic.

The 18-electron rule is helpful in predicting the stabilities of metal carbonyls and related compounds.

Carnelley based his rule on examination of 15, 000 chemical compounds.

Conjugated, planar, cyclic compounds that follow Hückel's rule are aromatic and exhibit an unusual stability.

This is a tendency, not a rule, as noble gases and other " inert " gases can react to form compounds.

Many transition metal compounds violate this rule due to the formation of complex ions.

It is typically extracted from the root-bark or the fruit of sassafras plants in the form of sassafras oil ( although commercially available culinary sassafras oil is usually devoid of safrole via a rule passed by the FDA in 1960 ), or synthesized from other related methylenedioxy compounds.

The placement of double bonds in many alicyclic compounds can be predicted with Bredt's rule.

The electrophiles frequently seen in the organic syntheses are cations such as H < sup >+</ sup > and NO < sup >+</ sup >, polarized neutral molecules such as HCl, alkyl halides, acyl halides, and carbonyl compounds, polarizable neutral molecules such as Cl < sub > 2 </ sub > and Br < sub > 2 </ sub >, oxidizing agents such as organic peracids, chemical species that do not satisfy the octet rule such as carbenes and radicals, and some lewis acids such as BH < sub > 3 </ sub > and DIBAL.

According to the Meyer-Overton correlation the anaesthetic potency of the drug is directly proportional to its lipid solubility, however, there are many compounds that do not satisfy this rule.

Hückel's rule is not valid for many compounds containing more than three fused aromatic nuclei in a cyclic fashion.

Antiaromatic compounds usually fail Hückel's rule of aromaticity.

Phase I and II reactions serve to increase the polarity and reduce the toxicity of the compounds, although many exceptions to the rule are seen.

For hypervalent compounds in which the ligands are more electronegative than the central, hypervalent atom, resonance structures can be drawn with no more than three covalent electron pair bonds and completed with partially ionic covalent bonds to obey the octet rule.

Destructive distillation of any particular inorganic feedstock produces only a small range of products as a rule, but destructive distillation of organic materials commonly produces very many compounds, often hundreds, though not all chemical products of any particular process are of commercial importance.

He worked on organic compounds and proposed Zaitsev's rule, which predicts the product composition of an elimination reaction.

On January 17, 2001 EPA published a final rule ( 66 FR 4500 ) that classified lead and lead compounds as PBT chemicals and lowered their reporting thresholds.
