◦ 2KClO₃→ 2KCl +

O₂

◦ 4P₄ + 5S₈→ 4P₄S₁₀

◦ P₄ + 5O₂→ P₄O₁₀

Question 2

Which of the following statements is always true concerning a reaction represented by the following balanced chemical equation?
2C₂H₆(g) + 7O₂(g) → 6H₂O(l) + 4CO₂(g)

◦ If we have equal masses of C₂H₆ and O₂, there is no limiting reactant.
◦ If we have an equal number of moles of C₂H₆ and O₂, there is no limiting reactant.
◦ If we have more mass of C₂H₆, then O₂ must be limiting.
◦ If we have more mass of O₂, then C₂H₆ must be limiting.
◦ None of these statements are true.
