For testing oxygen(PURE),you can use a glowing splint.If it relights,it is PURE oxygen.
For testing oxygen(EXIST),you can use a burning splint,if it burns more brightly,it contains of oxygen.
~Other ways to test different gas~
Carbon dioxide:for testing carbon dioxide,you can use lime water and hydrogencarbonate indicator.If the hydrogencarbonate indicator turns from red to yellow,it contains of carbon dioxide.If the lime water changes from milky to colourless,it contains of carbon dioxide as well.These reaction dunn appear in oxygen and nitrogen.
Nitrogen:If you have tested a gas with hydrogencarbonate indicator,lime water,burning splint,as well as glowing splint.Still it has no reaction.Then it is nitrogen cause it is a very unreactive gas.
Do you know how to test for water and water vapour?Use a dry cobalt paper!if it turns to pink from light blue,it contains of water and water vapour:-)
You can also breath to test for oxygen.
Yes, elevation affects the amount of oxygen available in the air. As elevation increases, the air pressure decreases, leading to lower oxygen levels. This can make it harder to breathe and can cause symptoms of altitude sickness.
Oxygen concentration in water can be tested using a dissolved oxygen meter or a chemical test kit. The dissolved oxygen meter measures the amount of oxygen dissolved in the water, while a chemical test kit uses reagents to indicate the oxygen level based on a color change. Both methods provide an accurate assessment of oxygen concentration in water.
The amount of air in an oxygen tank varies depending on its size. A standard medical oxygen cylinder typically holds between 244 and 682 liters of oxygen at a pressure of 2,000 psi.
During expiration, the air in the lungs has already been used for gas exchange in the alveoli, leading to a decrease in oxygen and an increase in carbon dioxide levels. This results in the drop in the amount of oxygen between inspired and expired air.
You can test for the presence of oxygen gas by using a glowing splint test. A glowing splint will reignite in the presence of oxygen. Alternatively, you can use a chemical reaction like the decomposition of hydrogen peroxide, which produces oxygen gas bubbles. Additionally, you can use an oxygen gas sensor to directly measure the presence of oxygen in the air.
Air is 20.5 percent oxygen.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
The amount of oxygen in the air is about 0.21 moles per liter.
If you put a lit match in a test tube of oxygen it will burn with more energy.
No, humid air does not have less oxygen compared to dry air. The amount of oxygen in the air remains the same regardless of humidity levels.
No

no effect
No it isn't. It is Nitrogen, which makes up 70% of the air we breathe.
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium
