The reaction that occurred is called a decomposition reaction. For instance, when carbon dioxide and water are formed from carbonic acid. It is a type of reaction where it involves a single compound breaking down into two or more products. These reactions often requires an energy source thus is an endothermic reaction.acid base acid base-7 -1.74 15.74 21 ( (pKa or pKb) Note the pK values. In general, an acid and base will react only if the reaction products are a weaker acid and a weaker base than the reagent acid and reagent base. Stated otherly... A stronger acid will donate H+ to a base whose conjugate acid is weaker (higher pKa) or

This paper studies the chemical attachment of pyridine on two semiconductor surfaces, Si(100) and Ge(100), at low coverages. We use thermodynamic arguments to show that the aromaticity of pyridine is preserved in both cases at low temperatures. At high temperatures, a transition toward nonaromatic structures—tetrapod structure for Si(100) and dipod structure for Ge(100)—occurs without ...NIOSH POCKET GUIDE TO CHEMICAL HAZARDS.
