Chapter 104

2009-10-22 · Solutions of inorganic acids are not flammable in themselves; however, when they come into contact with certain other chemical substances or coustible materials, a fire or explosion may result. These acids react with certain metals with the liberation of hydrogen, which is a highly flammable and explosive substance when mixed with air or oxygen.

4.1: Chemical Reactions and Chemical Equations - …

Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties. For example, water (H 2 O) and hydrogen peroxide (H 2 O 2) are chemically distinct substances. H 2 O 2 decomposes to H 2 O and O 2 gas when it comes in contact with the metal platinum, whereas no such reaction occurs between water and platinum.

Carbon - Element information, properties and uses

It is this metastability of diamond that is exploited in chemical vapour deposition. A gas mixture of 99 % hydrogen and 1 % of methane is used and some activation source like a hot filament employed to produce highly reactive hydrogen and methyl radicals. The carbon-based molecules then deposit on a surface to form a coating or thin film of

Zinc chloride - Wikipedia

2019-4-7 · Zinc chloride is the name of chemical compounds with the formula ZnCl 2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. [citation needed] ZnCl 2 itself is hygroscopic and even deliquescent.Samples should therefore be protected from sources of moisture, including the water vapor present in aient air.
