AI Thread Summary
Limestone is utilized in paper production primarily to whiten and add bulk, with "provide bulk" referring to its role in enhancing the paper's thickness and weight. Weathering processes are influenced by water, wind, air, and temperature fluctuations. The distinction between wind action and air action may lie in the mechanical effects of wind versus the chemical interactions of air. Rusting alters a metal's properties by introducing oxygen and moisture, leading to the formation of oxides that change the metal's appearance and structural integrity. The properties of most oxides typically include increased hardness and changes in color and reactivity. The reaction between chalk (calcium carbonate) and nitric acid can be represented as calcium carbonate + nitric acid → calcium nitrate + carbon dioxide + water. The discussion also touches on the destructive elements in the air, suggesting that if air were composed solely of argon, it would not cause the same corrosive effects on metals due to the lack of reactive components.

Limestone is used to whiten and provide bulk to paper.
What is the meaning of 'provide bulk'?

Weathering occures through the actions of water, wind, air and changes n temperature.
What is the difference between wind action and air action?

What properties are changed/added/subtracted when a metal rusts?

Please write a word equation of the reaction between chalk and nitric acid.

What is the difference between wind action and air action?

What is in the air that destroys things? If the air was made of argon, would it still destroy metals?

What properties are changed/added/subtracted when a metal rusts?

What are the properties of most oxides?

Please write a word equation of the reaction between chalk and nitric acid

calcium carbonate + nitric acid --> calcium nitrate + carbon dioxide + something else?
 
What is the difference between wind action and air action?

Perhaps wind means mechanical action and air chemical action. But that's just a guess.

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
