Natural gas in homes burns in excess of oxygen, what is the limiting reactant in this case?
Correct answer: B. Natural gas
- A. Oxygen
- B. Natural gas
- C. Air
- D. There is no limiting reactant
Explanation
The limiting reactant is the substance that gets completely consumed first, stopping the reaction from continuing. Since oxygen is in excess, the natural gas (primarily methane, CH₄) is the limiting reactant because it determines how much combustion occurs.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
