very simple.. stay in a room that has a mixture of gas except oxygen.. then u will confirm urself..!! else try this, keep a beaker inverted over the unlighted gas stove and make the gas collected in the beaker, now immediately put an alive insect (try with mice or frog), close the mouth of beaker tightly and wait for few seconds.. if it is a glass beaker u can notice the suffocation of test animal inside the beaker due to lack of oxygen
What else can I help you with?
How does oxygen get into the leaf?
experiment to show the presence of in a leaf
How to prove that there are brass in sand?
To prove that there are brass particles in sand, you can perform a simple experiment by using a magnet. Brass is not magnetic, so if you pass a magnet over the sand and some particles are attracted to the magnet, it indicates the presence of a metal like brass in the sand. You can then separate the brass particles from the sand using the magnet as proof.
What is the purpose of detecting the presence of starch in leaf?
It can be used to prove that photosynthesis has happened.
How do you prove that sand has salt particles?
One way to prove that sand has salt particles is by performing a simple experiment. You can dissolve the sand in water and then evaporate the water, leaving behind any salt particles present in the sand. Another method is to analyze the composition of the sand using chemical testing, which can detect the presence of salt particles.
What famous experiment did Galileo conduct and what did prove?

How can you prove by experiment to show that starch is produced in the presence of sunlight?
Aim of an experiment to show that starch is produced in the presence of sunlight

What can an experiment do?
Prove causation
How did your experiment prove or disprove the hypothesis?
That depends on the result of the experiment. The experiment is a way to test a hypothesis, and it's completely fine if the experiment disproves the hypothesis. Ideally, though, the experiment will support the hypothesis.
What is the different between obligate anaerobe and facultative anaerobe?
Facultative anaerobes does not need o2 to grow but can also grow with o2. Obligate anaerobe cannot grow at all in the presence of o2.
Why is evidence important in an experiment?
to prove it worked.
Who was the scientist who did an experiment to prove gravity?

Cellular respiration occurs in the presence of?

Does science prove theories are wrong by using experiments?
An experiment can prove they are wrong or right ...:)
Why does the urey-miller experiment not prove that life started that way?
The Urey-Miller experiment simulated early Earth conditions and produced organic molecules like amino acids, but it did not create life. Life is more than just the presence of organic compounds; it involves complex processes like self-replication and metabolism. The experiment provides insight into how building blocks of life can be formed, but it does not prove how life actually began.
How can you prove which material blocks light the best?
By experiment.
How was the Michelson Morley experiment used to deceive even Einstein?
This was an experiment to prove universal gravitation!
