If a solid is heated to give off carbon dioxide and water, it must contain at carbon, oxygen, and hydrogen atoms. One such substance is the bicarbonate ion, which is formed from hydrogen and water with the loss of a proton. In fact, when salts of this ion are sufficiently heated, they decompose to water and carbon dioxide.
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
Carbon dioxide gas becomes a solid when heated under certain conditions. This process, known as deposition or sublimation, involves the direct transition of carbon dioxide from a gas to a solid without passing through a liquid phase.
Solid carbon dioxide, also known as dry ice, sublimes directly into carbon dioxide gas when heated. So, if it is heated from -100oC to -78oC, it will transition from a solid directly to a gas without passing through the liquid phase.
some solids turn straight into a gas when heated. This process is called sublimation. A good example is solid carbon dioxide, also called dry ice. At atmospheric pressure, it turns straight into gaseous carbon dioxide
When chalk is heated, it undergoes a decomposition reaction and produces carbon dioxide gas (CO2) and calcium oxide (CaO). The carbon dioxide gas is released as bubbles, while the calcium oxide remains as a solid residue.

Solid turns directly into gas through the process of sublimation. This occurs when the solid is heated and skips the liquid phase to directly become a gas. An example of this is dry ice (solid carbon dioxide) turning into carbon dioxide gas without melting.
After heating at high temperature calcium carbonate is decomposed in calcium oxide (solid) and carbon dioxide (gas).
When chalk is heated, it undergoes a decomposition reaction and produces carbon dioxide gas (CO2) and calcium oxide (CaO). The carbon dioxide gas is released as bubbles, while the calcium oxide remains as a solid residue.
It decomposes into calcium oxide and carbon dioxide...
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
Solid carbon dioxide is frozen and is commonly known as dry ice.
Solid carbon dioxide is not dangerous but avoid contact with skin and eyes.
Carbon dioxide is a gas that can be changed to a solid. When turned to a solid carbon dioxide becomes dry ice.
