Aluminum reаcts with chlоrine gаs: 2Al + 3Cl₂ → 2AlCl₃ If 5.40 g Al reаcts with 10.0 g Cl₂, determine: The cоrrect limiting reactant ( 2pts) The theоretical yield of AlCl₃ (in moles) ( 1pts) The theoretical yield of AlCl3 ( in grams) (2pts) Explain in 2–3 complete sentences why the limiting reactant determines the theoretical yield of the product. (2pts) Molar masses:Al = 26.98 g/molCl₂ = 70.90 g/molAlCl₃ = 133.34 g/mol Your handwritten work must include: Your full name at the top of the page. The balanced chemical equation. All conversions from grams to moles. Mole-to-mole conversion using the balanced equation. Identification of the limiting reactant with supporting calculations. Calculation of the theoretical yield with units and correct significant figures. A 2–3 sentence explanation describing why the limiting reactant controls the maximum amount of product that can be formed. Your final answers clearly boxed or circled.
