Answer:

The weight residue of obtained CO2 is 14 grams.

Explanation:

When CaCO3 is heated strongly, its decomposes to give carbon dioxide gas (CO2) and CaO. The presence of carbon dioxide gas can be tested by passing it through lime water which turns milky, showing signs of presence of the gas.

The decomposition of limestone calcium carbonate is thermal decomposition. This reaction uses heat energy for decomposition of CaCO3. It decomposes, when heated above 840°C releasing gas and a white solid.
