A student reacts 0.200 mol of phosphorus (P₄) with excess oxygen to produce phosphorus pentoxide (P₄O₁₀). The balanced equation is: P₄(s) + 5O₂(g) → P₄O₁₀(s) The student collects 52.0 g of P₄O₁₀. The molar mass of P₄O₁₀ is 284 g/mol. Which statement correctly discriminates between theoretical yield and experimental yield?
Distinguish between theoretical yield and experimental yield for the decomposition of magnesium carbonate. Explain your reasoning.
In a laboratory synthesis of aspirin from salicylic acid and acetic anhydride, a student calculates that 4.32 g of aspirin should form based on stoichiometry. When the reaction is completed and the product isolated, the student obtains 3.78 g of aspirin. Which statement correctly distinguishes between these two quantities?
