1. A mixture of two oxides (barium oxide and calcium oxide -4.88 g total) was reacted with a quantity of carbon dioxide gas at 35 °C and 746 mmHg in a 1.46 Liter flask. At the reaction's end, the pressure in the flask fell to 252 mmHg. Calculate the percent composition of the mixture. Note: The combination of a metal oxide with carbon dioxide gas will form a carbonate salt as the only product. Lithium hydride (LiH) reacts with water...

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)....

CaCO3(s) = Cao (s)+CO2 (g) When heated strongly, solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas, as represented by the equation above. A 2.0 mol sample of CaCO3(s) is placed in a rigid 100. L reaction vessel from which all the air has been evacuated. The vessel is heated to 898°C at which time the pressure of CO2(g) in the vessel is constant at 1.00 atm, while some CaCO3(s) remains in the vessel. a. Calculate...
