When malachite is heated, it decomposes into copper(II) oxide and carbon dioxide. The word equation for this reaction is: Copper(II) carbonate (malachite) → Copper(II) oxide + Carbon dioxide.
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O
The word equation for heated mercury is "mercury reacts with oxygen to form mercury oxide."
4Na + O2 ----> 2Na2O Sodium oxide is formed.
When sodium carbonate is heated, it decomposes into sodium oxide and carbon dioxide. The word equation for this reaction is: Sodium carbonate → Sodium oxide + Carbon dioxide.
The word equation for sodium hydrogen carbonate when heated is: sodium hydrogen carbonate (sodium bicarbonate) → sodium carbonate + carbon dioxide + water.
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O

The word equation for the breakdown of solid mercury(II) oxide when heated is: Mercury(II) oxide --> Mercury + Oxygen.
In order to extract copper from malachite, the malachite must be heated to a high temperature. This produces a fine black powder (copper Oxide). The copper oxide is heated again to a more extreme temperature, this removes the oxygen, leaving metallic copper.
When baking powder is used in baked products it produces carbon dioxide
Malachite is a copper carbonate mineral that can be toxic if ingested. It can release toxic fumes when heated or burned, so care should be taken when handling it. Dust from malachite can also cause respiratory irritation, so it is important to work with it in a well-ventilated area and use protective gear.
