Subang to thogong boyredo ne TO el gubwollo) sa zoban visart 5. The analysis of a rocket fuel showed that it contained 87.4% nitrogen and 12.6% hydrogen by weight. The fuel's molar mass was determined to be 32.05 g by mass spectral analysis. Determine the empirical and mo- lecular formulas of the fuel. 4 marks 5. In this reaction: 6 PbO (s) + O2(g) 2 Pb304(s), if 225 g of PbO are combined with 225 g of O2, what mass of Pb304 is produced (think limiting reagent!)? 4 marks Communication. Answer the following questions in the spaces provided. 1. Write the name of the following compounds; 1 mark each a) HO b) H3PO4(aq) b) CoCl 6 HO d) CuO 6 Subang to thogong boyredo ne TO el gubwollo) sa zoban visart 5.
