A process of fermentation occur.
If it's exposed to pure oxygen then nothing will happen. If it's exposed to air then the carbon dioxide in air will make it go cloudy. Lime water is the test for the presence of carbon dioxide.
Calcium tarnishes rapidly when exposed to air.
The paint on a car helps to protect the underlying metal from oxidation and rust. Once this paint is removed, that metal is exposed to the air and will start to erode.
If an iron nail is exposed to air for a long time it reacts with the water vapour (moisture) and oxygen present in the atmosphere and a reddish-brown powdery coating is formed on it known as RUST (Fe2O3.xH2O) .
it evaporates
nothing
Alkaptonuria is an inherited condition that causes urine to turn black when exposed to air.
Rust is formed in metals when it exposed to oxygen and moisture in air and in the presence of acid.
it gradually looses its color.
If it's exposed to pure oxygen then nothing will happen. If it's exposed to air then the carbon dioxide in air will make it go cloudy. Lime water is the test for the presence of carbon dioxide.
The moist cloth will start to cool
Uric acid may crystallize and settle out since it is only slightly soluble in water or acid solution.
what will happens to a plant exposed to air
what happens when they are exposed to water
Calcium tarnishes rapidly when exposed to air.
Nothing will happen if you touch your rabbit's urine, unless you have a skin reaction to rabbit urine, which is highly unlikely.
Yes. It might not occur as fast, but the water is still exposed to the air.
