(ii) What volume of CO 2 at RTP would be produced if 23.9 g of CaCO 3 was decomposed? 11. What volume of hydrogen (H 2 ) is produced when 0.056 g of lithium (Li) reacts completely with water at STP? 2Li (s) + 2H 2 O (l) → 2LiOH (aq) + H 2 (g) 12. Sodium hydroxide reacts with carbon dioxide as follows: 2NaOH(s) + CO 2 (g) →Na 2 CO 3 (s) + H 2 O( l ) (a) Which reagent is the limiting reactant with 68.0 g NaOH and 40.4 g CO 2 are allowed to react? (b) How many grams of Na 2 CO 3 can be produced? (c) How many grams of the excess reactant remain after the completion of the reaction? (d) What is the percent yield of Na 2 CO 3 if only 84.6 g of it is produced? 13. *A solution of sodium hydroxide contained 0.25 molL -1 . Titration of 25.0 mL of this solution required 22.5mL of a HCl solution for complete neutralisation. HCl (aq) + NaOH (aq) → NaCl (aq) + H 2 O (l) (a) Calculate the moles of sodium hydroxide neutralised. (b) Calculate the moles of HCl neutralised. (c) Calculate the concentration of the HCl in molL -1 (molarity). 14. What is the molarity of potassium hydroxide solution if 38.65 ml of the KOH solution is required to titrate 25.84 ml of 0.1982 M of hydrochloric acid solution? 15. *In an experiment, a student titrated 0.1060 g of sodium carbonate (Na 2 CO 3 ) dissolved in water with a standard 0.09115 M hydrochloric acid (HCl) solution from a burette.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
