How is oxygen prepared using sodium peroxide?
Oxygen can be prepared from sodium peroxide by heating it, which causes it to release oxygen gas. The chemical reaction involved is 2 Na2O2 → 2 Na2O + O2. The oxygen gas can then be collected and used for various applications.
What is chemical formula for oxygen?
The chemical formula for oxygen is O2 and for individual oxygen atom its symbol is O. Gases such as oxygen exist as diatomic molecules.
Why is sodium thioglycollate used in lab media?
Sodium thioglycollate is used in lab media to reduce the oxygen content in the medium, creating an anaerobic environment. This is useful for growing and studying anaerobic bacteria that cannot survive in the presence of oxygen. Sodium thioglycollate helps to maintain anaerobiosis by chemically binding to oxygen.
Where does the oxygen in earths atmosphere come from?
The origin of oxygen (and other large elements) is from supernovae. On the smaller scale, the vast majority of our oxygen comes from ocean plants, from tiny algae to giant kelp. The atmospheric oxygen comes from the decomposition of water and carbon dioxide by organisms that use photosynthesis to make useful molecules in combination with the energy from sun light.
What do trees produce?
Trees produce oxygen through the process of photosynthesis. They also provide food, shelter, and support for various animals and insects. In addition, trees absorb carbon dioxide from the atmosphere and help regulate the climate.
Is oxygen useful or harmful?
It is useful because we can breathe it.
How is ozone can be harmful or useful when it absorbs ultraviolet rays and changes into normal oxygen?
Ozone is useful. The oxygen forms again transforms to form ozone.
What is the most used elements?
The most useful element is oxygen because without it we wouldn't be a able to breathe.
Which is most useful and dangerous gas to human being?
Oxygen is the most useful gas to human beings as it is essential for respiration. Carbon monoxide is considered the most dangerous gas to humans as it can displace oxygen in the bloodstream, leading to carbon monoxide poisoning, which can be fatal.
What are the useful substances the coronary artery supply?
food oxygen
What is it about oxygen that makes it useful?
it helps us breath and live
What useful waste products is made in photosynthesis?
Oxygen and glucose.
What is the most useful atom?
Every atom is useful.Example is oxygen.
What useful substance in the air do human being used?
oxygen
When is oxygen useful to life in what form?
It is useful to life because all living organisms need it. In a gas form.
Is it useful or harmful when ozone in the upper atmosphere absorbs ultraviolet rays and changes into normal oxygen?
The oxygen formed in upper atmosphere is not for breathing. It forms again into ozone by natural phenomenons.
Why is oxygen useful to us?
We inhale oxygen for breathe. Also, animals and plants depend on it as well. It forms atmosphere so that air can stay on Earth and also a need of fire.
