No, however they can be combustable when compressed or mixed with air.
Flour is a powder. It is biodegradable and environmentally friendly. When mixed with the proper amount of air it is quite explosive.
Acetylene is a colourless, combustible gas with a distinctive odour.When acetylene is liquefied, compressed, heated, or mixed with air, it becomes highly explosive.
Only if mixed with a suitable oxidiser, most notably the air. thus a fine dispersion of graphite in the air can be ignited with explosive violence. Also whats known as "graphitic oxide" is explosive and this is formed from oxidation of graphite powder with nitric acid.

Vehicular Battery Off-gassesYes, when a lead-acid battery is either charged or discharged it emits gasses [vapors]. Although there could be others, the primary gas is Hydrogen [H2], and sometimes Hydrogen Sulphide [H2S].If and when mixed in the proper ratio with the air, both of these gasses are highly explosive!!!!!

Yes. Explosive when mixed with oxygen or fluorine and even chlorine gas. Hydrogen is flammable. It burns in air or oxygen.

Coal dust in the air is an explosive mixture, because the mixture of coal and air can burn much more rapidly than solid pieces of coal can (flour in the air is also explosive, or sawdust - any flammable substance in the form of dust becomes explosive if it is mixed into the air). The process of mining coal is messy, and creates a lot of dust. And any spark can set it off. No smoking in the coal mines!
Answer 1 - Out-gassing of Auto BatteriesNO, the out-gassing from auto batteries while being charged, AND while being DISCHARGED is HYDROGEN [H2] which is HIGHLY FLAMMABLE, AND when mixed in the proper proportion [ratio] with air that Hydrogen gas is EXPLOSIVE.
COAL! Highest levels of carbon dioxide and other harmful substance including the ash that it leaves behind.

yes they did
magma flows upward mixed with ash. it cools quickly when thrown up in the air and become pyroclastic blocks bombs and boulders which are the main cause of fatalities
Fuel is mixed with air and enters cylinders; the misture is compressed and a spark plug ignites the explosive mix causing a rapid expansin of gases- that is called a powe strock.
