Combustion is an exothermic reaction, generally categorized by the release of energy through heat or light.

A combustion reaction must occur between oxygen and a fuel. The products vary from incomplete to complete combustion. Incomplete combustion occurs under the lack of oxygen, which complete combustion occurs under excess oxygen.

As long as reaction contains a fuel and oxygen, plus the need to heat, it should be a combustion reaction. The common products formed are CO2 and H2O.

Sometimes there are gases that are combustable.

You are the only person who can tell YOUR reaction.

This is an endothermic chemical reaction.

You need to calculate the yield of the reaction.

Very much so. It is a main fuel in our Sun.

You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.

There are various ways that you can tell when a chemical reaction has finished. For example, the mass of all of one of the chemicals is gone.

You can tell if it is exothermic when it starts to lose heat.

It's highly explosive, combustable and flammable.

tasteless, colorless, non-combustable, gas (at STP)

No, however they can be combustable when compressed or mixed with air.

Only at high temperatures, forming BeO and Be3N2.

Generally. That means it's highly combustable.

Give me the reaction, then I may be able to tell you the form.

tell me the full answer of that question plz
