Is carbon dioxide a flamable gas?

Answer 1

Actually, when at room-temp its non-flamable.

No. This is the gas you exhale and is used in fire extinguishers. The oxygen is bound to the carbon. According to the National Fire Protection Association, it will not burn.

Answer 2

Yes.

I am a chemical engineer who has patented a method for making nanodiamond by making a detonatable explosive that is based on dry ice (frozen CO2) and an appropriate reducing agent (RA) according to the following equation:

CO2 + RA -----> C + RA-oxide + Energy

One reducing agent is silane gas: SiH4

A mixture of silane and CO2 would be about as explosive as methane and oxygen and the reaction would proceed as follows:

CO2 + SiH4 -------> C + SiO2 + 2 H2(gas)

Carbon dioxide burns very aggressively with certain metals (reducing agents), and so there are therefore special fire extinguishers that are used specifically to deal with fires involving those metals. An example of such a metal is aluminum. Aiming a CO2 fire extinguisher at an aluminum fire would simply encourage the fire to burn.

Answer 3

No. CO2 is the product of combustion in many cases and is very good at smothering fires when used in large quantities. Fires require oxygen to burn, so when all of the oxygen is replaced with carbon dioxide, the fire will go out. Just as fires require oxygen to burn, we require oxygen to live. Replace the oxygen with carbon dioxide and we die just like a fire that's run out of oxygen. CO2 is the exact opposite of flammable.

Answer 4

No. Carbon dioxide is a product of combustion. In it, the carbon is fully oxidized.

Answer 5

Yes. It is categorised as highly flammable; it can even be used to fuel an engine.

Answer 6

No, and that's not how you spell flammable.

Answer 7

Carbon dioxide is certainly and in ALL circumstances NONflammable.

It is a good fire extinguisher (car and oil fires).
