You are given an unknown gaseous binary compound (that is, a compound consisting of two different elements). When 10.0 g of the compound is burned in excess oxygen, 16.3 g of water is produced. The compound has a density 1.38 times that of oxygen gas at the same conditions of temperature and pressure. Give a possible identity for the unknown compound.
Answer to relevant QuestionsUse the following information to identify element A and compound B, then answer questions a and b. An empty glass container has a mass of 658.572 g. It has a mass of 659.452 g after it has been filled with nitrogen gas at a ...Consider the following chemical equation: 2NO2(g) → N2O4(g) If 25.0 mL of NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O4 occupy? Helium is collected over water at 25oC and 1.00 atm total pressure. What total volume of gas must be collected to obtain 0.586 g of helium? (At 25oC the vapor pressure of water is 23.8 torr.) An unknown diatomic gas has a density of 3.164 g/ L at STP. What is the identity of the gas? a. If the open-tube manometer in Exercise 22 contains a nonvolatile silicone oil (density = 1.30 g/cm3) instead of mercury (density = 13.6 g/ cm3), what are the pressures in the flask as shown in parts a and b in torr, ...
