Question

what happens when ZnCO3 is heated in the absence of air? give the relevant equation ​

Answer 1

Explanation:

Hi ! ZnCO₃ , when heated in the absence of air , gets converted to ZnO , and CO₂ gas is also evolved. This process , of converting carbonates ores into oxides , in the absence of air ( limited supply) , is known as calcination. This metal oxide , is later on converted to metal , by reducing it with Carbon.

Answer 2

Answer:

znco 3 heated to form zinc oxide+carbon dioxide

Explanation:

when the zinc carbonated heated to form zinc oxide and release carbon dioxide that why the air is not release in the equation zinc carbonate
