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?
Limestone is cooled in a dry argon atmosphere to prevent any unwanted reactions or changes in the limestone due to exposure to moisture or oxygen. The dry argon atmosphere helps maintain the integrity of the limestone and ensures that the cooling process is conducted under controlled conditions.
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 the solid remaining was cooled in a dry argon atmosphere?
Cooling the solid in a dry argon atmosphere helps protect it from reacting with oxygen or moisture in the air, which can affect its purity and properties. Argon is an inert gas, meaning it does not react with the solid and creates an oxygen- and moisture-free environment to maintain the solid's integrity.
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.
Most abundant noble gas in atmosphere?
The most abundant noble gas in Earth's atmosphere is argon, which makes up about 0.934% of the atmosphere.
How much argon is in Venus's atmosphere?
In both lunar rocks and the atmosphere of Venusthe Argon 40/argon 36 ratio is 1:1 while in the atmosphere of Earth argon 40 is 99.6%
How much argon is present in the earth's atmosphere?
At about 1% of Earth's atmosphere, argon is the 3rd-most plentiful of the atmosphere's elements.
How argon is separated from air?
Argon is separated from air by a process called cryogenic distillation. Air is cooled to very low temperatures to liquefy and then slowly heated up. As different components of air have different boiling points, argon is separated from other gases based on its boiling point which is lower than that of nitrogen and oxygen.
Is argon found in the air?
Yes there is argon in the air in the atmosphere
Is argon created by lightning?
No, argon is a noble gas that is naturally present in Earth's atmosphere and is not created by lightning. Lightning can generate ozone and nitrogen oxides in the atmosphere, but not argon.
Is there more carbon dioxide in the atmosphere than argon?
Yes, there is more carbon dioxide in the Earth's atmosphere than argon. Carbon dioxide makes up about 0.04% of the atmosphere, while argon makes up about 0.93%.
