You do the same test as you would have done in year 7, the pop test. Invert a test tube and fill partially with the gas then place a lit match or candle at the bottom if you hear a pop you have hydrogen. just don't be like my old teacher and fill it to the point half the room catches fire. Hope this helps

How do you make a fair test in an experiment?
Use same equipment/apparatus
What are three examples of qualitative?
- test of chlorine in water - test of sodium in a mixture by flame test - test of hydrogen sulphide in a gas mixture
How many variables can be changed in a fair test?
Only one at a time, since you would not know which variable(s) made the observed changes. You would need to measure each change separately. But if you want to test multiple variables, then you would need to test every possible permutation. If you want to test two chemicals, then you should test your control (a placebo using neither substance), substance A, substance B, and both substances.
What is the objective of test?
You need to state which test you are talking about.
What is the internal test?
The internal test would be logical consistency. The external test would be observation of the real world.
If an inverted tube containing air is placed above a test tube of hydrogen why would the tube of air give a positive test for hydrogen after a few minutes?
This would happen because of the process of diffusion. Hydrogen molecules would move from the hydrogen test tube where they are highly concentrated to the air test tube where their concentration is low.
How would you test a gas if it is hydrogen?
burn it?
What laboratory apparatus used for supporting the test tube when not in used?
apparatus
What chemical test would you do to test for hydrogen halide acids?
Light a splint. Hold it above a test tube with the unknown gas in it and if the splint goes out with a sqeaky pop then there is hydrogen.
What would you classify hydrogen?
test it with burining wooden splint
What would a sentence with the word hydrogen in it look like?
Example sentence - The answer to the first question on the test is hydrogen.
What is the standard test for hydrogen?
Insert a lighted splint into the reaction test tube. If it extinguishes with a "pop" sound, Hydrogen is present. The duller the pop the purer the hydrogen is.---------------------------------------------------------------------------------------------P.S. that's a burning splint.
Uses of test tube in laboratory apparatus?
used to chemical test
What is the test for hydrogen gas called?
the hydrogen pop test
State a test for the presence of hydrogen?
The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
How would you test to see if a gas is hydrogen?
it will burn with a pop noise
What is the apparatus name used to hold test tubes?
A test tube rack.
