Ha, I had this exact same question in my AP Chem Class, stumped me for a minute too. 6CaO + P4O10 → 2 Ca3(PO4)2
It decomposes into calcium oxide and carbon dioxide
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
Calcium carbonate heated to form calcium oxide and carbon dioxide as shown by the equation CaCO3(s) → CaO(s) + CO2(g).
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
The equation for the thermal decomposition of calcium carbonate into calcium oxide and carbon dioxide is: CaCO3 (s) -> CaO (s) + CO2 (g)
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.
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
Yes. Calcium carbonate can neutralize acids, producing carbon dioxide and a calcium salt that corresponds to the acid.
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.
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.
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.
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.
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
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.
It decomposes into calcium oxide and 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.
