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
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 experiment?
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.
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.
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)

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.
The titrant should be placed in the burette at the beginning of the experiment.
In Priestley's bell jar experiment, a lit candle is placed inside a bell jar, which is then sealed. As the candle burns, it consumes oxygen and produces carbon dioxide, leading to a decrease in oxygen levels within the jar. Eventually, the flame extinguishes due to insufficient oxygen for combustion. This experiment demonstrated the importance of oxygen for burning and laid the groundwork for understanding gases in respiration.
The results of the frog in hot water experiment showed that when a frog is placed in hot water, it will immediately jump out to avoid harm. However, when the frog is placed in cold water and the temperature is gradually increased, the frog will not perceive the danger and will stay in the water until it is too late. This experiment is often used as a metaphor to illustrate how individuals may not react to gradual changes or dangers in their environment until it is too late.
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.
Well depends what gas you put in if it oxygen then it will evaporate but if it a gas which is flamable, it explode
Oh, dude, the dependent variable in the egg in a bottle experiment is the volume of air inside the bottle. It's like the thing that changes based on what you do to the egg and the bottle. So, if the egg gets sucked into the bottle, it's because of that variable, not because the egg wanted to take a vacation in there.
When the bottle is placed in hot water, the air inside expands due to the increased temperature. This causes the balloon to inflate as the air pressure inside the bottle increases.
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.
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.
When the bottle was placed in cold water, the air inside the bottle cooled down and contracted, causing the bubble to shrink or collapse. The decrease in temperature led to a decrease in the volume of air in the bottle, making the bubble appear smaller or disappear.
