Question 2 In a laboratory determination of the empirical formula of tin oxide, Sn,O,, a sample of tin is weighed in a crucible Nitric acid is added and then the mixture is heated, and the reaction proceeds to give Sn O,, NOz and HO The unbalanced reaction equation is shown below. The products are further heated in the crucible t0 obtain the dried tin oxide. Sn (s) + HNO; (aq) Sn 0, (s) + H,O (g) + NO_ (g) The following data is collected: Mass crucible (g- 11.25 Mass Sn and crucible (g) 12.25 Mass of dried Sn O,and crucible (g 12.52 (a) Determine the mass of Sn and mass of dried Sn 0 , (b) Determine the empirical formula of Sn 0 (c) Explain the effect on the calculated empirical formula that would result from each of the following experimental eTors: The reaction mixture bubbles over the crucible upon reaction of the HNO; (aq) with the Sn (s) . (ii) The tin oxide product is not heated sufficiently to dry it completely: (d) Is the reaction below an oxidation-reduction reaction? Justify your answer. Sn (s) + HNO; (aq) Sn O, HO (g) + NO; (g) (e) Sn,0,(s) has a high melting - point when compared to H,O (s) Explain such an observation using the strength ot the particle torces present In the compounds.
