The easy way of balancing the chemical equation is_________?
Correct answer: C. First we balance Metal than non-metal than Hydrogen than Oxygen.
- A. according to atom's atomic number.
- B. According to atom's atomic mass.
- C. First we balance Metal than non-metal than Hydrogen than Oxygen.
- D. None of the above
Explanation
For many ordinary equations, a convenient inspection order is to balance metals first, then other nonmetals, followed by hydrogen and oxygen. This is a practical shortcut because hydrogen and oxygen often occur in several compounds and are easier to balance at the end. Students may choose atomic mass or atomic number, but chemical equations are balanced by conserving atoms, not by matching those properties.

About Balancing Redox Equations
Redox equations are balanced by tracking electron loss and gain through oxidation numbers or the ion-electron method. Work includes identifying oxidizing and reducing agents, balancing atoms and charge in acidic or basic medium, and ensuring that electrons lost equal electrons gained.
