Chemistry
In the Haber-Bosch process, nitrogen and hydrogen gas are reacted under high temperature 500 degrees C and pressure 200 atm to form ammonia gas (NH3) according to the following equation: N2+3H2 = 2NH3 If 9300 L H2 gas is reacted with an excess of N2 gas at 200 atm and 500 degr...

Chemistry
A baker uses sodium hydrogen carbonate as the leavening agent in a banana nut quickbread. the baking soda decomposes according to two possible reactions. 1. 2 NaHCO3 = Na2CO3+H2O+CO2 2. NaHCO3+H=H2O+CO2+Na. calculate the volume in mL of CO2 that forms at 180 degrees C and .975...

Chemistry
on a particularly hot 30 degrees C day near the seashore the partial pressure of water vapor in the air is .0303atm. given that the atmospheric pressure is 1 atm and the composition of dry air is 78% N, 21% O and 1%Ar, what is the partial pressure of oxygen gas?

Chemistry
The running engine of an automobile produces carbon monoxide (CO), a toxic gas, at the rate of about .102mol CO per minute. a car is left idiling in a poorly ventilated garage that is 60m long, 4 m wide, and 2.2 m high at 20 degrees C. what will the partial pressure of CO in o...

Chemistry
The water from a hydrated magnesium salt is driven off by heat in a closed system. If the steam generated exerts a pressure of 24.8 atm in a 2L container 120 degrees C, determine the number of moles of H2O driven from the compound.

Chemistry
A sample of natural gas at STP is 78% CH4 and 22% C2H6 by volume how many moles of each gas are present in 1.60L of the mixture?

Chemistry
Aqueous sulfurous acid (H2SO3) was made by dissolving .200L of sulfur dioxide gas at 19 degrees C and 745 mmHg in water to yield 500mL of solution. the acid solution required 12mL of sodium hydroxide solution to reach the titration end point. what was the molarity of the sodiu...

Chemistry
He is the lightest noble gas component of air, and Xe is the heaviest. Perform the following calculations, using R=8.314J/(molXK)and M in kg/mol. 1. Find the average kinetic energy per mole of He and Xe at 30 degrees C. 2. Find the average kinetic energy per molecule of He at ...
