A fuel gas containing about 5o percent carbon monoxide 40 percent hydrogen and small amount of methane, carbon dioxide and nitrogen made by passing stem and air over heated coke and coal.
Hydrogen gas is produced.
Hydrogen gas
The gas that is produced if you blow carbon dioxide in boiling water is carbonic gas (H2CO3).
The gas produced when sodium metal is added to cold water is hydrogen gas.
Hydrogen
Hydrogen gas is produced when sodium is added to water. This reaction is highly exothermic and can result in the sodium igniting.
If one chemically reacts oxygen gas and hydrogen gas, any liquid produced is water.
When hydrogen burns, water vapor (H2O) is produced as a byproduct.
water vapor
Hydrogen.
Hydrogen and oxygen
You can test for the gas produced by collecting it in a test tube and then performing tests like the "pop" test using a burning splint. The gas produced when sodium reacts with water is hydrogen gas, which will ignite with a "pop" sound when exposed to a flame.
