Question

What would happen if oxygen stops to support combustion make a guess and if it is the situation for what other works fuel are useful

Answer 1

Oxygen only makes up about 20 % of the atmosphere, not the majority.  The majority is actually nitrogen (N2) which constitutes about 78 %.

Oxygen doesn't burn on its own though, it needs a fuel.  That fuel is your match stick, when that fuel is gone, it stops burning.  There's nothing else to burn so the fact that there's a decent amount of oxygen around isn't dangerous. tt

Answer 2

Explanation:

The digestion of food in our stomach is a process of combustion . Food is broken down by reaction with oxygen. Then energy is released. If oxygen loses this property , no man can survive . Then there will be no human beings to guess about anything.

Hope this helps you guys.
