Why does limestone after it is heated the solid was cooled in a dry argon atmosphere?

Limestone, when heated produces calcium oxide (CaO) and carbon dioxide (CO2). CaO is highly reactive and will combine with CO2 from the atmosphere to reverse the above process. It will also react with any water vapour in the atmosphere to form calcium hydroxide (CaOH). These reactions can be prevented by allowing the CaO to cool in an inert environment such as that provided by argon.

Why is limestone cooled in a dry argon atmosphere?
because argon doesn't react
Why is limestone cooled in a dry argon atmosphere after being heated?
Limestone, when heated produces calcium oxide (CaO) and carbon dioxide (CO2). CaO is highly reactive and will combine with CO2 from the atmosphere to reverse the above process. It will also react with any water vapour in the atmosphere to form calcium hydroxide (CaOH). These reactions can be prevented by allowing the CaO to cool in an inert environment such as that provided by argon.
Why the solid remaining was cooled in a dry argon atmosphere?
Argon does not react with limestones
Why would a welder use helium and argon gases during welding?
Argon is an inert gas so metals can be heated to a high temperature in an argon atmosphere without any danger of their reacting with surrounding materials.
What percentage of the atmosphere is argon?
The standard atmosphere contain 0,934 % argon.
What is the argon percentage in Earth's atmosphere?
The percentage of Argon in the atmosphere is 0.93% in volume.(0.934 to be more accurate-pip)The atmosphere is 0.934% argon by volume, so, a lot of argon.The earth's atmosphere has a volume of about 3x1024 m3, which means that there are about 2.8x1022 m3 (5x1012 mi3) of argon in the atmosphere. The density of argon is about 1.77 kg/m3 so there are about 1.58 kg of argon in the atmosphere.
