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.

When solid calcium carbonate is heated what is form?
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
Which gas becomes a solid when heated?
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.
What happens to a piece of solid carbon dioxide if its heated from -100oC to -78oC?
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.
Can you name a solid that turns straight from a solid into a gas?
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 a chalk is heated it produces?
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.

When does solid turns straight into a gas?
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.
Is CaCO3 considered a solid after being heated?
After heating at high temperature calcium carbonate is decomposed in calcium oxide (solid) and carbon dioxide (gas).
When a chalk is heated it produces?
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.
When Calcium carbonate is heated .?
It decomposes into calcium oxide and carbon dioxide...
What are the products when limestone is heated strongly?
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
What do you understand by solid carbon dioxide?
Solid carbon dioxide is frozen and is commonly known as dry ice.
Can solid carbon dioxide disposed?
Solid carbon dioxide is not dangerous but avoid contact with skin and eyes.
What gas can be changed into solid?
Carbon dioxide is a gas that can be changed to a solid. When turned to a solid carbon dioxide becomes dry ice.
