9. A gas sample that causes a smoldering object to ignite and burn intensely would be categorized as a(n).
flammable gas
O oxidizer
O inert gas
O All of the above

Option d (All of the above) is the right option.

Explanation:

A flammable gas seems to be a gas which, whenever presented with either an ignition source, explodes throughout the possession of even an oxidant. Throughout a redox reaction, each oxidizer seems to be a reactant that eliminates electrons from several other reaction mixtures. Inert gas would be a gas which, throughout appropriate circumstances, doesn't undergo another chemical reaction.

Since flammable gas, oxidizing agent, inert gas all allow smoldering material to the flame which burns severely, the solution is all of those.

The gas would begin to expand, and eventually the can would burst or explode.
