We are huge packages of chemicals.

Living organisms are created by chemistry.

What that means is, I can mix some chemicals together in a test tube in my lab, and these chemicals will start to self associate to form larger and larger structures.

If we count the number of chemicals in that system, actually, including the water that's in the dish, we have five chemicals that can do this.

284 An oxygen generator, chemical, containing oxidizing substances should meet the following conditions

The members of drafting group on chrysotile asbestos established by the first meeting of the Chemical Review Committee were Mr. K Berend and Mr.

Just with blobs of chemicals, again.

usage of high risk chemicals materials

Atoms are chemically inseparable and building blocks of matter. Atoms of one kind are called an Element.

But it's just one chemical.

Those blooms are generating other kinds of chemicals.

It actually takes things we would consider waste things like seed husks or woody biomass and can transform them into a chitinous polymer, which you can form into almost any shape.

Chemistry, my fellow, is the material manifestation of the metaphysical.

(d) The Act on Chemical Substances implements various EC directives and stipulates that new chemical substances are to be registered with information as to their potential hazard.

Products or masses of goods

The lines around the edges are a polymer.

Effects of harmful chemical and other substances

The highest risks are associated with the laboratory handling of dangerous organic and chemical substances.

That terminology has stuck, but it doesn't actually refer to specific chemicals because these chemicals come in a lot of different shapes and forms.

This is a DNA synthesizer, and here at the bottom are just bottles of A, T, C and G the four chemicals that make up our DNA chain.

So maybe the chemical in that would be useful.

The chemistry from compounds in the environment is orders of magnitude more complex than our best chemists can produce.

Products or masses of goods

Fixtures and products or masses of goods

Now, what are the ideal conditions for chemistry?

Prohibiting the use of chemical substances not marked in a way allowing for their identification

The European Trade Union Confederation (ETUC) is participating in the chemical substance policy review of the European Union Commission with the goal of a comprehensive system for the registration, evaluation and authorization of chemicals.

NOTE 1 Mixtures of oxidizing substances, meeting the criteria for classification as oxidizing substances, which contain 5.0 or more of combustible organic substances and which do not meet the criteria mentioned in (a), (c), (d) or (e) above, shall be subjected to the self reactive substances classification procedure .

Meteorites delivered chemistry, and perhaps membranes, too.

Chemical substances and precursors were subject to strict controls.

But of course, life is more than just exotic chemistry.

Matter that cannot be broken down into simpler matter. Chemical elements are cornerstones of Materials. Elements consist of atoms that consist of a nucleus of positive protons, neutral neutrons, and a shell of electrons.

Food additive means any synthetic compound or natural substance put into food to improve its quality, colour, fragrance or taste, or for the sake of preservation or processing.

During a chemical reaction mass is neither lost nor gained. The sum mass of the material going into the reaction equals the sum of the mass of the products of the reaction.

This was a result that the first reaction when we saw the water turning green was to use one of the chemicals chlorine that is very common in swimming pools.

The following main chemicals are restricted arsenic and arsenic compounds, benzine, cadmium, formaldehyde, lead, mercury, nickel, organic tin, PCB, pentachlorophenol, PCT, ozone depleting substances and a wide range of specific chemicals in cosmetics.

And this particular plant removes formaldehydes and other volatile chemicals.

are authorized for the transport of any liquid or solid substance other than explosives, thermally unstable substances, organic peroxides, self reactive substances, substances where significant pressure may develop by evolution of chemical reaction and radioactive material (unless permitted in 4.1.9).

I want to know if there's a chemistry of morality.

We banned those chemicals, and we replaced them, unknowingly, with other substances that, molecule per molecule, are a hundred times more potent as heat trapping, greenhouse gases than carbon dioxide.

It's like electrical shock that releases the chemicals from these synapses.
