A panic attack is an exaggeration of your bodyâs normal response to fear, stress or excitement. It is the rapid build-up of overwhelming physical sensations, such as: 1  a pounding heartbeat. 2  feeling faint. 3  sweating. 4  nausea (feeling sick).
Since four elements must be present for the combustion process to occur (fuel, heat, an oxidizing agent, and a chemical chain reaction), a fire can be extinguished by removing any one of these four elements.
The generic algebraic equation for a combustion reaction is: AB + oxygen â common oxide of A and B. In a complete combustion reaction, a reactant burns with oxygen to produce the most common oxides of the elements making up the substance that is burned.The combustion of methane means that it is possible to burn it. Chemically, this combustion process consists of a reaction between methane and oxygen in the air.he generic algebraic equation for a combustion reaction is: AB + oxygen â common oxide of A and B. In a complete combustion reaction, a reactant burns with oxygen to produce the most common oxides of the elements making up the substance that is burned.
