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
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 .
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
I'm pretty sure Ca is a solid at room temperature
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.
When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
Calcite, mineral consisting largely of calcium carbonate (CaCO3). Therefore it is a solid
Calcium carbonate is a solid, such as chalk or limestone.
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
CaCO3 is solid at room temperature
