When calcium carbonate (CaCO₃) is heated or undergoes thermal decomposition, it breaks down into calcium oxide (CaO) and carbon dioxide (CO₂). The reaction can be represented by the equation: CaCO₃ → CaO + CO₂. This process is commonly observed in the production of lime for various industrial applications. The release of carbon dioxide is also significant in contexts like baking and environmental chemistry.

What happens when carbon dioxide is treated with limewater?
When carbon dioxide is treated with limewater (calcium hydroxide solution), a white precipitate of calcium carbonate forms. This is a chemical reaction that is commonly used to test for the presence of carbon dioxide gas.
What happens to calcium carbonate when heated?
It decomposes into calcium oxide and carbon dioxide
How do you measure the amount of carbonate in a rock?
hydrochloric acid + calcium carbonate ▬▬► calcium chloride + carbon dioxide + water
What are two compounds that contain carbon?
Calcium carbonate; carbon dioxide are two
Calcium carbonate heated to from calcium oxide and carbon dioxide well balanced equation?
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
What are 3 examples of a compound?
water,carbon dioxide, and calcum carbonate
How is carbon released from calcium carbonate?
When calcium carbonate is heated, it undergoes thermal decomposition to produce calcium oxide and carbon dioxide. This reaction releases the carbon that was originally part of the calcium carbonate as carbon dioxide gas.
What is formed when calcium carbonate decomposes?
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
What gas is produced when calcium carbonate and hydrochloric acid is mixed?
Carbon dioxide gas is produced when calcium carbonate and hydrochloric acid are mixed. This reaction occurs as the acid reacts with the calcium carbonate, releasing carbon dioxide gas as a byproduct.
When 20g of calcium carbonate are decomposed by heating 8.8g of carbon dioxide are given off. Work out the mass of calcium carbonate that would be required to give 22g of carbon dioxide.?
Using stoichiometry, we can calculate the molar ratio between calcium carbonate and carbon dioxide. When 20g of calcium carbonate decompose to form 8.8g of carbon dioxide, the molar ratio is 1:1. Therefore, to produce 22g of carbon dioxide, you would need the same mass of calcium carbonate, which is 20g.
What is the equation for heating calcium carbonate?
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
What do sulfuric acid and calcium carbonate make?
Sulfuric acid and calcium carbonate react to form calcium sulfate, carbon dioxide gas, and water. This is a chemical reaction where the acid reacts with the carbonate to form a salt, releasing carbon dioxide in the process.
Solid calcium oxide is exposed to a stream of carbon dioxide gas?
A chemical reaction will occur, resulting in the formation of calcium carbonate and releasing heat. This reaction is known as calcium oxide reacting with carbon dioxide to form calcium carbonate.
Can calcium carbonate neutralize an acid?
Yes. Calcium carbonate can neutralize acids, producing carbon dioxide and a calcium salt that corresponds to the acid.
Word equation for the reaction between calcium carbonate and methanoic acid?
Calcium carbonate reacts with methanoic acid to produce calcium methanoate, carbon dioxide, and water. The word equation for this reaction is: calcium carbonate + methanoic acid → calcium methanoate + carbon dioxide + water.
Why sulphuric acid is not used in preparation of carbon dioxide from calcium carbonate?
Sulfuric acid is not suitable for preparing carbon dioxide from calcium carbonate because it reacts with calcium carbonate to form calcium sulfate, water, and carbon dioxide. This reaction can be impractical and difficult to control because it produces an additional product (calcium sulfate). It is more efficient to use a weaker acid, such as hydrochloric acid, which will react only with the calcium carbonate to produce carbon dioxide and water.
What gas will be produced between hydrochloric acid and calcium carbonate?
carbon dioxide carbon dioxide
