A review of chemistry, a round of review, chemistry in the sixth chapter, burning and fuel, learning outline Review of 1. substances combustion target navigation conditions, the definition of burning, fire extinguishing principle, promote combustion method, what is the preliminary knowledge explosion, explosion prevention; classification of main components and material of 2. coal and petroleum, chemical equation of combustion of methane, acetylene and other material to write; preparation of 3. carbon dioxide (drugs, device, collection method, test method), with the physical properties of carbon dioxide, chemical formula chemical properties and reactions. Knowledge review section 1: fire and fire fighting knowledge 1: combustion 1. combustion: combustible and a violent reaction occurring. Note: (1) light and heat is burning, such as lamp light and heat, and no change is generated. (2) not all burning in, such as hydrogen in chlorine, combustion, fuel temperature to reach 2. combustion conditions: must be satisfied at the same time its own. Note: the ignition point is the minimum temperature required for fuel combustion, can reduce or increase the temperature, reduce the ignition temperature. 4., the method of promoting combustion: (1) increase, increase. The two methods increase the number of molecules colliding with the fuel and oxygen, and thus promote the complete combustion of the fuel. The complete combustion of the fuel can save and reduce the environment. Knowledge 2: fire extinguishing method of 1.: (1) (2) (3). Knowledge 3: explosion 1. explosion is combustible combustion in a limited space, in a short period of time to gather a large number of gas volume caused by explosion. Conditions for explos
