When $\text{MgCO}_3(s)$ is strongly heated, it produces solid $\text{MgO}$ as gaseous $\text{CO}_2$ is driven off.

Does the oxidation number of carbon change upon the formation of $\text{CO}_2$?

Question

When $\text{MgCO}_3(s)$ is strongly heated, it produces solid $\text{MgO}$ as gaseous $\text{CO}_2$ is driven off.

Does the oxidation number of carbon change upon the formation of $\text{CO}_2$?

pyromorphite · Answer

MgO + CO_2\uparrow"> M g C O 3 ​ − − T − − > M g O + C O 2 ​ ↑ 
 the oxidation number of carbon in MgCO3 = +IV the oxidation number of carbon in CO2 = +IV 
 so, there is no change

When \(\text{MgCO}_3(s)\) is strongly heated, it produces solid \(\text{MgO}\) as gaseous \(\text{CO}_2\) is driven off.
