Question

Problem Page Question Solid calcium carbonate decomposes into solid calcium oxide and carbon dioxide gas . Write a balanced chemical equation for this reaction.

Answer 1

The balanced chemical equation is:

`CaCO_(3)` →
`CaO + CO_(3)`

Step-by-step explanation:

The problem said:

Solid calcium carbonate decomposes into solid calcium oxide and carbon dioxide gas.

Corresponde to chemicale equation:

`CaCO_(3)` →
`CaO + CO_(3)`

A chemical reaction must be based on the law of the conservation of matter, which implies that matter is not created or destroyed but transformed. Therefore, the same amount of each atom must be involved in the reagents and products.

this reaction have:

Reagents.

1. Ca = 1
2. C = 1
3. O = 3

Products.

1. Ca = 1
2. C = 1
3. O = 3

∴ This equation is balanced.

Answer 2

Δ

CaCO3(s) → → CaO (s) + CO2 (g)

Explanation: Calcium Carbonate also known as Limestone will undergo decomposition reaction in the presence of heat to produce Quick-lime and Carbon dioxide.
