Is hydrogen flame able?
Yes. Explosive when mixed with oxygen or fluorine and even chlorine gas.
Hydrogen is flammable. It burns in air or oxygen.
Hydrogen and carbon dioxide cannot be seen how could you use a wooden splint and a flame to identify each of these gases?
The hotter a hydrocarbon gas burns, the bluer the flame. An orange flame indicates a cool flame with incomplete combustion since soot (unburnt carbon) glows orange. Hydrogen gas burns so completely and so hot that it emits light in the ultraviolet. You cannot see a hydrogen gas flame. Alcohol fires, similarly, tend to burn very efficiently and are nearly invisible--as anybody who watches NASCAR races knows.
First of all we will have to know that what is a flame made up of,a flame is made at a point where fuel and oxygen combine,so in case of both candle and coal there is a fuel ie.wax in candle and coal is itself a fuel.................but if we just think till this much then even coal should produce flame but it doesn't go like this ,actually we are missing something ie. hydrogen(the main component…
