(a)
Interpretation:
The balanced equation for the preparation of molecular oxygen has to be given indicating the physical state of the reactants and products.
Concept Introduction:
- Chemical equation is the representation of a chemical reaction, in which the reactants and products of the reactions are represented left and right side of an arrow respectively by using their respective chemical formulas.
- Reactant of a chemical reaction is the substrate compounds or the compounds which undergo a chemical reaction.
- Product of a chemical reaction is the produced compounds or the compounds formed after a chemical reaction.
- Balanced chemical equation of a reaction is written according to law of conservation of mass.
