Under STP conditions, 100.0 mL of an unknown hydrocarbon gas was combusted in excess oxygen. The only products of the combustion were 300.0 mL of carbon dioxide and 400.0 mL of water vapor. a. What are the intermolecular forces common to hydrocarbon gases? b. Does the behavior of these gases tend to resemble ideal gas behavior? How might these gases be expected to deviate from this behavior? c. How many moles of carbon dioxide are produced in the combustion? d. What is the formula of the hydrocarbon? e. If the combustion were performed at 2.50 atm and 500°C, how many liters of water vapor would you expect to produce? NH3 and HCI are released at opposite ends of a glass tube.
