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.
The word equation for heating a substance in air typically describes the process of combustion. For example, if we consider the combustion of a hydrocarbon like methane, the word equation would be: methane + oxygen → carbon dioxide + water. This represents the reaction that occurs when methane is heated in the presence of air (which contains oxygen), resulting in the production of carbon dioxide and water vapor.
When baking powder is used in baked products it produces carbon dioxide
