4A. When 1.00 L of an unknown gaseous compound that contains only C, H, and N is burned In oxygen, 2.00L of carbon dioxide, 4.00L of water vapor and 2.001. of nitrogen dioxide are produced at the same temperature and pressure. 1) What volume of O₂ (g), in liters, was needed for this reaction? II) What is the empirical formula of the gaseous compound? 48. Given the balanced redox reaction: 2 H₂S (g) + 3 O₂(g) - 2 H₂O (1) +2 SO2 (g) AHrxn--1124 kj 1) which element is undergoing oxidation? H, S, or O II) for the element being oxidized, what is its starting oxidation number and its final oxidation number? Il-a) Starting ox. number__ Il-b)Final ox. number III) how many total electrons are transferred in the reaction? iv) if 10.0L of H₂5 (g) held at 735 mmHg and 22.5°C is reacted with excess oxygen and all of the heat released is completely transferred to 1.50 gallons of water initially at 15.0°C, what would be the final temperature of the water? (assume the density of water is 1.00 g/mL)
