After heating at high temperature calcium carbonate is decomposed in calcium oxide (solid) and carbon dioxide (gas).
When limestone (CaCO3) is heated, calcium oxide is produced!
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
Calcium carbonate (CaCO3) is typically found in a solid state, such as in the form of limestone or chalk.
I'm pretty sure Ca is a solid at room temperature
caco3 is solid form. its density is high so caco3 is not soluble in water. but co2 mix in water befuor the mix in caco3 . so caco3 is soluble after mixing the co2 .
CaCO3 (calcium carbonate) is most likely to occur as a solid at room temperature.
When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
When a solid is heated it expands and if is heated enough it will melt; it may also boil. If you cool it down it will go back to solid form.
Calcite, mineral consisting largely of calcium carbonate (CaCO3). Therefore it is a solid
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
Solid, liquid and gas will expand on heating. One exception is water that expands on being heated, and on being frozen into solid ice.
A liquid is like a solid because a liquid I usually a heated solid Ex. Water is heated ice
