(5) Calculate the volume of CO₂ gas at STP obtained by reacting a 10.00 g sample of calcium carbonate with an excess of hydrochloric acid: CaCO3(s) + 2 HCl(aq) → CaCl₂(aq) + CO₂(g) + H₂O (1) (6) A student prepared Na₂CO3 by bubbling CO₂ through an aqueous solution of NaOH: 2 NaOH(aq) + CO₂ → Na₂CO3(aq) + H₂O(1) If 15.0 g of NaOH was used, what mass of Na₂CO3 is expected? (7) Balance the following equations (1) - - NaOH + ---- (2) ---- KMnO4 → ---- ---- Al → ---- Al2O3+ - K₂O + H₂+ ---- MnO + ---- 0₂ Na₂O (5) Calculate the volume of CO₂ gas at STP obtained by reacting a 10.00 g sample of calcium carbonate with an excess of hydrochloric acid: CaCO3(s) + 2 HCl(aq) → CaCl₂(aq) + CO₂(g) + H₂O (1) (6) A student prepared Na₂CO3 by bubbling CO₂ through an aqueous solution of NaOH: 2 NaOH(aq) + CO₂ → Na₂CO3(aq) + H₂O(1) If 15.0 g of NaOH was used, what mass of Na₂CO3 is expected?
