Question

Combustion is the process in which a substance reacts with oxygen to give off heat. Example:a magnesium ribbon starts burning when heated in flame. Given a combustible substance and oxygen,if the substance reaches its ignition temperature,it will start burning.Spontaneous combustion is a special case of combustion where a material burns without heat being supplied from an external source.Example:a piece of phosphorous suddenly starts burning when kept in a dish on a table.What could be the LIKELY reason for spontaneous combustion to happen? A. Non metals absorb heat from the atmosphere more quickly than metals and are likely to combust spontaneously because of this. B. Materials that combust spontaneously have a special property- they need not reach the ignition temperature to combust C. Spontaneous combustion is a process that requires only the presence of the combustible substance ;heat and oxygen are not required. D. In the case of substance that combust spontaneously, a chemical reaction take place which generates the heat required for combustion.

Answer 1

Answer:

As magnesium being more reactive metal it reacts with oxygen spontaneously and burns spontaneosly
