To test for hydrogen in the given substance, a dry sample is needed.
Burn it in excess of oxygen. If the vapour turns white copper sulfate into blue colour, it indicates that there is water in present in the vapour. Hence, the organic compound contains hydrogen.

What is a positive test for each of the following gases oxygen hydrogen carbon dioxide?
the positive test for oxygen is very simple. all that needs to happen is a vile must be filled 1/4 with hydrogen peroxide and a glowing splint must be inserted in t the vile . the splint will reignite after it is inserted int the vile.
Why seliwanoff's test is positive only for keto sugars?
Ketose reacts more readily with seliwanoff's test because:= ==Ketones have 3 carbon atoms where Aldehyde has 2 hydrogen atoms and one carbon atoms.=
What elements are in lipids?
Lipids are compounds, not elements. Most lipids are triacyl esters of glycerol and fatty acids. They consist of three elements mostly: Carbon, Hydrogen and Oxygen. (Sometimes Nitrogen and/or Phosphorous may be included as well)

How can you check if bubbles are hydrogen or carbon dioxide?
well, to check you have to preform the pop test. the pop test is a test that you add fire to the container that the acid is in. if it pops its hydrogen but if it doesn't its carbon dioxide.
How Long Can carbon monoxide be detected in a blood test after you quit smoking?
Carbon Monoxide will always be detected in the blood, but after 1-2 days the level will be no different to that of a non-smoker.
How would you test carbon dioxide to show that it was hydrogen?
Carbon dioxide form a milky suspension of calcium carbonate in calcium hydroxide; hydrogen doesn't react. But hydrogen react with oxygen when a flame exist.
