What is contained in a clean dry test tube?
If a test tube is clean and dry, then there should be nothing in it.
What test would you use to distinguish between nitrogen an oxygen?
You can test for oxygen by placing a glowing splint (not lit but not out) into the test tube where you think oxygen is present. If the splint relights, that means that it is oxygen. If this doesn't happen, then in your case it will be nitrogen.
What test would allow you to tell the difference between carbon dioxide and nitrogen why would the burning splint test not work?
You stated that carbon dioxide and nitrogen are present, but you did not mention oxygen. Nothing burns without oxygen . . . If you expose limewater to carbon dioxide, it will get cloudy, but will not if you expose it to nitrogen.
If you collected the gas produced by the photosynthesizing leaves how would you check if it contained oxygen?
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
How do you distinguish between nitrogen oxide and oxygen using a chemical test?
Use a sample of pyrogallol (C6H6O6) in the sample followed by a combustion reaction. This compound absorbs oxygen present.
What gas is evolved when a few crystals of potassium nitrate are heated in a hard glass test tube?
Nitrogen dioxide and oxygen are released.
Air is mostly composed of?
Im pretty sure its composed of elements that are nonmetals. taking a test recently said that they were not noble gasses.
In the electron transport chain the main purpose of the you breathe is to keep electrons moving along from thr first to the last chemical carrier?
Oxygen.... Thought it was Nitrogen, but ti's oxygen, got it wrong on test, right answer is oxygen.
Do animals need nitrogen to breathe?
No, in fact most early spacecraft the test animals, astronauts, or cosmonauts breathed pure oxygen. This was stopped after the Apollo-1 fire, which was attributed to defective wiring and a pure oxygen atmosphere. After that some nitrogen was added as a safety feature against fire.
What does a blood urea nitrogen test do?
The blood urea nitrogen (BUN) test measures the level of urea nitrogen in a sample of the patient's blood.
What is the speed of sound in a mixture of oxygen and nitrogen?
The speed of sound through nitrogen is about 354m/s, and the speed of sound through oxygen about 332m/s, so a mixture of both would be about, I guess,( 354m/s + 332m/s) ÷2 = 343m/s. This question was on my phsics test something like 3 years ago. Hope this helps on your test or whatever. :) (I just seriously hope you're not cheating! LOL)
What is the standard test for nitrogen?
N
