Answer 2

Substance "Gassed" by Water Without Burning

Water can "extinguish" certain substances that do not burn.

Some substances, such as sodium and potassium, react violently with water, producing hydrogen gas, which can ignite and cause an explosion. In these cases, the reaction with water is not a combustion process, but it can lead to the release of flammable gases.

Calcium carbide is another example of a substance that reacts with water to produce flammable acetylene gas, which can ignite.

In addition, phosphorus is another substance that can react with water, producing phosphine gas, which is highly toxic and flammable.

These reactions with water are not combustion processes, but they can lead to the release of flammable or toxic gases, which is why they are often referred to as being "gassed" by water.
