2PbO(s) → 2Pb(s) + O₂(g)
Here's what the equation shows:
* 2PbO(s): Two moles of solid lead oxide (PbO) are the reactants.
* 2Pb(s): Two moles of solid lead (Pb) are produced.
* O₂(g): One mole of oxygen gas (O₂) is produced.
Explanation:
When lead oxide (PbO) is heated to a high temperature, it decomposes into its constituent elements: lead (Pb) and oxygen (O₂). The oxygen is released as a gas, while the lead remains as a solid.
