Quotes About Compounds

Kate was especially intrigued by entries in the book showing scientific notations for chemical compounds. The long, complicated sequences of elements left her wondering what sort of substances these ingredients produced. Had her ancestors managed to preserve some of Valerian's ancient formulas for alchemy potions?

Paradoxically, the United States' determination to protect its troops can be self-defeating. Allies and adversaries see U.S. forces living in secure compounds, eating fancy chow and minimizing their exposure to potential terrorist assaults.

Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist.

Aluminum is a metallic element—one of the principal constituents of the earth's crust. Only oxygen and silicon are more abundant. Aluminum does not occur naturally in its pure form, but only in a wide variety of compounds.

Today chemists can artificially make hundreds of thousands of organic compounds, most of which are not duplicated in nature.

regrowth. Compounds like magnesium, quercetin, resveratrol, niacin, zinc, and N-acetyl cysteine. What to Eat, What to Avoid Eat These Avoid These

Eat for flow. Certain spices and herbs have medicinal effects on lymph flow because they contain compounds that help prevent

In organic chemistry, we have learnt to derive from compounds containing only carbon and hydrogen, i.e. from the hydrocarbons, all other types of combinations, such as alcohols, aldehydes, ketones, acids, etc.

In bitter almond oil, like in a great number of other substances that previously had been counted among the 'aromatic compounds' on behalf of their strong smell, a derivative of benzene is present. The special properties of benzene and its derivatives are caused by the typical arrangement of their carbon atoms.

And there must be simple substances, because there are compounds; for the compound is nothing but a collection or aggregatum of simples.

For the London in which he had grown up had been a congeries of estates, parks, and compounds

This resulted in an exponential rise in CFC production. The annual global output of the two dominant compounds, F-11 and F-12, later known as CFC-11 and CFC-12 or R-11 and R-12, rose from less than 550 tons in 1934 to more than 50,000 tons in 1950, to about 125,000 tons in 1960, and then it soared to the peak of 812,522 tons in 1974, with the US accounting for nearly half of the total

The verdict was obvious: CFCs were staying in the atmosphere, and because of their inertia nearly their entire post-1930 output was accumulating aloft. But did the presence of these compounds, as Lovelock's group concluded, pose "no conceivable hazard" because they did "not disturb the environment"—or could their accumulation have undesirable consequences?

There are, in fact, very few organic zinc compounds; only the first members of the series, which correspond to the simplest organic radicals, can be prepared without too much difficulty, but they have the disadvantage of being spontaneously inflammable in air and are consequently very dangerous to handle.

Disgust is often more deeply buried than envy and anger, but it compounds and intensifies the other negative emotions.

If the young man ate candy, the wrangler says, that's probably what's kept him alive so long. Glucose is a natural antidote to cyanide poisoning. Based on anecdotal evidence, glucose binds with the cyanide to produce less toxic compounds.

Medical chests of the era contained a brass mortar and pestle to grind compounds, and a selection of surgical

the formal structural descriptions full of cis-1,3-dimethyl-this and 2,5-di-tert-butyl-that

In general, exchange reactions for the lighter isotopes have equilibrium constants sufficiently different from unity, so that the ratios of concentrations of the isotopes in two compounds which are in equilibrium differ by a few per cents in nearly all cases.

We will create life from inanimate compounds, and we will find life in space. But the life that should more immediately interest us lies between these extremes, in the middle range we all inhabit between our genes and our stars.

Robert Boyle (1626-1691) had defined an element as a substance which could not be decomposed, but which could enter into combination with other elements giving compounds capable of decomposition into these original elements.

N-methyl-4-phenyl-1236

There is thy gold, worse poison to men's souls, Doing more murder in this loathsome world, Than these poor compounds that thou mayst not sell.

As soon as we can wrest from Nature the secret of the internal structure of the compounds produced by her, chemical science can then even surpass Nature by producing compounds as variations of the natural ones, which the living cell is unable to construct.
