One bottle would have more pure oxygen then the other one, since oxygen is more dense then air, and will not rise into the atmosphere or combine with air quick

Who invented the egg in a bottle experiment?

These are experiments where an egg is sucked into a bottle, when -- the bottle is heated, then allowed to cool -- a burning piece of paper is placed inside These have been used to demonstrate the effects of -- temperature and pressure -- the chemical binding of oxygen by oxidation ...and have been around since the 19th century (anytime since the invention of the glass milk bottle around 1877).


What would happen to the mass of each bag in this experiment if all the bags were placed in 0.4 M sucrose instead of distilled water?

What experiment?


What forms come off a frozen drink bottle when it is placed on the bench?

My opinion on this question, is that gases may come off the bottle, maybe even liquids, if the bottle is frozen enough, solids may drop off it as well.


Burning splint test for hydrogen gas?

hydrogen gas is H2 When H2 reacts with oxygen and fire (energy) It is combustion H2+ 02= 2(H20) Which is water. In that state it is water vapor. A popping noise is also made. That is water vapor racing out. The burning splint tests, basically, is when an individual lights a splint. On lighting this splint, it should be placed near a bottle containing hydrogen gas [ H2 ]. On carrying out this action, the glowing splint may increase in size, regarding the size of the flame, that is. The Hydrogen gas, on the other hand, will make a popping sound. The intensity of the 'pop' will depend on the amount of Hydrogen gas collected in the bottle. Take care to ensure that no Hydrogen gas escapes, or is released from the bottle, until the splint is placed, at least 2 inches away from the opening of the bottle.


What is the difference between a constant and a control group?

The constant is the base example that does not have any type of manipulation done to it. the control group would be the example that is manipulated in the same way that the other groups in the experiment are but without the addition of any of the reactants. Imagine your experiment was seeing the results of water boiling times. your constant would be the pot of water at room temperature without heat, the control group would be the pot that is placed on the stove being heated, and the Experimental group would be the one that you add salt to. (the variable that is being tested)

What proof do you have the oxygen is being given off during this experiment?

A simple school experiment is: A plant is enclosed inside a glass jar, and placed in sunlight and left to photosynthesis. A lit spill is blown out and, while still smouldering, is placed into the jar. Oxygen in the jar will ignite the spill.


What happens if you put a burning splint into nitrogen?

ah yes, the classic which gas is in which test tube experiment... Oxygen accelerates the combustion of organic material. The wood splint will burn more brightly and quickly if placed in oxygen. If the splint is 'blown out' leaving only a glowing tip it will reignite when placed in oxygen.


What will happen if 20 ml of water is placed in a plastic airtight bottle which is kept in sunlight for sometime and then some smoke is inserted in the bottle and it is again closed airtight?

Well depends what gas you put in if it oxygen then it will evaporate but if it a gas which is flamable, it explode


What happened to the bubble when you placed the bottle in cold water?

the air condenses and pulls the bottle in on itself


Why should screw cap of a reagent bottle be placed bottom up on the table?

If the cover of a reagent bottle is placed on a table with the bottom down, it can pick up material from the table which would contaminate the contents of the reagent bottle after the cap is put back on the bottle.


What happen when the bottle was gently placed on top of the flour?

Different things can happen if a bottle is placed gently on flour. If the flour is all spread out on a counter, then the bottle will leave prints in the flour. If the flour is packed tightly, then it is possible for the flour to be able to hold up the bottle.

How did a full sized pear get in pear brandy?

What is the theory behind the experiment in which a boiled egg is sucked into the bottle when an ignited match stick is put inside when the boiled egg being placed at the mouth of the bottle?

When the air cools it retracts creating a vacuum. The Vacuum then pulls the egg into the bottle. Since the vacuum acts equally across the surface of the egg, it is able to gently but quickly pull the egg through the opening without breaking it... most of the time.
