6 part question
1. describe the appearance of a Bunsen flame that is getting insufficient air?
2. describe the appearance of a Bunsen flame that is getting too much air.
3. When inserting glass tubing into a rubber stopper, how far from the stopper should you hold the tubing?
4. define the term filtrate.
5. define the term residue.
6. define the term precipitate.
Please explain what your problem is here. It seems to me that if you've seen a bunsen burner operate you should know the answer to 1 & 2. If you haven't seen one in operation you should.
For 3,5,5,6. Aren't these described in some detail in your lab manual or you can google for the definition.
