1.Ammonia is created in the Haber process in a rigid container (nitrogen gas plus hydrogen gas react to form ammonia gas). 2.0 moles of hydrogen gas are mixed with 4.0 moles of nitrogen gas. The initial pressure exerted on the container is 5.0 atm. Assuming the reaction runs to completion, what will the pressure (in atm) on the vessel be after the reaction takes place? 2.Pentane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas)....
