All materials require the presence of oxygen for burning to take place. Any substance burning in air will combine with oxygen. This process is called combustion, and is an example of a chemical reaction between the burning substance and the oxygen in the air, the reaction producing heat. The...
A chemical reaction: the reaction of two or more than two substances to another substance, called a combination reaction. The common chemical reactions in junior high school are mainly: 1, non-metallic elements and oxygen to produce non-metallic oxides. Such as 2H2+O2 H2O Other metals, such...

An important role of reactions with the participation of nucleophilic (electron-donating) reagents, including inorganic anions, in the transformation of the humus-mineral system of an acid soil is shown. Anion reactions can involve not only metal atoms of humus-mineral complexes but also the C ...
