No. A carbonate is a substance that contains either the carbonate ion or the bicarbonate ion.
Zinc carbonate decompose in ZnO and CO2.
thermaldecompositionMetal Carbonate ----------> Metal Oxide + Carbon dioxide
You think probable to the anion carbonate - CO2-3.
when the carbonate is heated in absence of air then the CO2 is produced as the byproduct .
This is the chemical formula of sodium carbonate.
When an acid reacts with a carbonate, a salt, CO2, and water is formed. For example: HCl + NaCO3 ---> NaCl + CO2 + H2O
NaHCO3 + CaCO3 = CO2 + CaCO3 + NaOH
Carbon dioxide = CO2. Carbonate = MeCO3 (Me is the cation)
The formula for cobalt (III) carbonate is Co2(CO3)3.
If you think to lithium carbonate the reaction is:Li2CO3------------------Li2O + CO2
CO2
Carbon Dioxide, or CO2, is dissolved in water to carbonate it. A "seltzer bottle" uses a CO2 cylinder to make carbonated water from tap water.
