Which of the following is a balanced chemical equation?
- a)H₂ + O₂ → H₂O
- b)2H₂ + O₂ → H₂O
- c)H₂ + 2O₂ → H₂O
- d)2H₂ + O₂ → 2H₂O
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Which of the following is a balanced chemical equation?a)H + O → ...
2H2 + O2 → 2H2O
The balanced chemical equation is:
- 2 molecules of hydrogen gas (H2) react with 1 molecule of oxygen gas (O2).
- This produces 2 molecules of water (H2O).
- Each side of the equation has 4 hydrogen atoms and 2 oxygen atoms, ensuring mass conservation.

Understanding Balanced Chemical Equations
A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, adhering to the law of conservation of mass.
Analysis of Each Option
- Option A: H + O → HO
- Reactants: 1 Hydrogen (H) and 1 Oxygen (O)
- Products: 1 Hydrogen (H) and 1 Oxygen (O)
- Not Balanced: The product is not represented correctly; water (H2O) is formed instead.
- Option B: 2H + O → HO
- Reactants: 2 Hydrogens (H) and 1 Oxygen (O)
- Products: 1 Hydrogen (H) and 1 Oxygen (O)
- Not Balanced: The hydrogen atoms are not equal on both sides.
- Option C: H + 2O → HO
- Reactants: 1 Hydrogen (H) and 2 Oxygens (O)
- Products: 1 Hydrogen (H) and 1 Oxygen (O)
- Not Balanced: There are more oxygen atoms on the reactant side.
- Option D: 2H + O → 2HO
- Reactants: 2 Hydrogens (H) and 1 Oxygen (O)
- Products: 2 Hydrogens (H) and 2 Oxygens (O)
- Balanced: The equation maintains equal numbers of hydrogen and oxygen atoms on both sides.
Conclusion
The correct answer is option D because it accurately represents a balanced reaction for the formation of water, confirming that both sides of the equation have equal numbers of each atom involved. This adherence to the conservation of mass is crucial in chemical reactions.
