The sole products of the complete combustion of a simple hydrocarbon are:
Correct answer: D. CO₂ and H₂O
- A. CO₂ and NH₃
- B. H₂O and Mg(ClO₄)₂
- C. CO₂ and KOH
- D. CO₂ and H₂O
Explanation
When a compound containing only carbon and hydrogen (a hydrocarbon) is burned completely in oxygen, the carbon forms carbon dioxide (CO₂) and the hydrogen forms water (H₂O).

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.
