Lead can be prepared from galena [lead(II) sulfide] by first roasting the galena in oxygen gas to form lead(II) oxide and sulfur dioxide. Heating the metal oxide with more galena forms the molten metal and more sulfur dioxide.
(a) Write a balanced equation for each step.



Answer :

An overall balanced equation for the process are

        PbS +O[tex]2[/tex]→ Pb +SO[tex]2[/tex]

What is balanced equation?

If both the reactants and the products of a chemical reaction have the same number of atoms and total charge, the equation for the reaction is said to be balanced. In other words, the mass and charge balances on both sides of the reaction are equal.

Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.

The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced.
