Question

When calcium carbonate is heated, it gives calcium oxide and carbon dioxide. Give the balance chemical equation. Which type of reaction is this ?

Answer 1

Explanation:

so hope its clear buddy☆

Answer 2

Answer:

CaO(s) + CO2(g) → CaCO3(s) However, above about 1200 K the opposite reaction occurs, calcium carbonate decomposes to form calcium oxide and gives off carbon dioxide. This is what happens in lime kilns where limestone (calcium carbonate) is heated to form lime (calcium oxide).
