In summary, limestone is used to whiten and provide bulk to paper. 'Provide bulk' refers to adding thickness or weight to the paper. Weathering occurs through the actions of water, wind, air, and changes in temperature. Wind action refers to mechanical forces, while air action refers to chemical reactions. The properties that are changed, added, or subtracted when a metal rusts include its color, strength, and ability to conduct electricity. Most oxides are known for their high melting points and strong nature. A word equation for the reaction between chalk and nitric acid is calcium carbonate + nitric acid --> calcium nitrate + carbon dioxide + water. In terms of air, the presence of certain chemicals can cause destruction to materials such

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 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.

1. What is limestone?

Limestone is a sedimentary rock composed mainly of calcium carbonate. It is formed from the accumulation of shells, corals, and other marine debris over millions of years.

2. What is weathering?

Weathering is the process of breaking down rocks, soils, and minerals through exposure to the atmosphere and other environmental factors such as water, wind, and temperature changes.

3. How does weathering affect limestone?

Weathering can cause physical and chemical changes to limestone. Physical weathering can occur through freeze-thaw cycles, where water seeps into cracks and freezes, causing the rock to break apart. Chemical weathering can occur through the reaction of limestone with acidic rainwater, causing it to dissolve and form new minerals.

4. How does metal react with limestone?

The reaction of metal with limestone depends on the type of metal. Some metals, such as iron and steel, can react with acidic limestone to form iron oxide, also known as rust. Other metals, such as aluminum and gold, are resistant to weathering and do not react with limestone.

5. Can you provide a word equation for the reaction between metal and limestone?

The word equation for the reaction between metal and limestone is: Metal + Acidic Limestone → Metal Oxide + Carbon Dioxide + Water
