In the Haber-Bosch Process, nitrogen and hydrogen gas are reaceted under high temperature (500 C) and pressure (200 atm) to form ammonia gas (NH3) according to the equation:
N2 + 3H2 ---> 2NH3
if 10500 L H2 gas is reacted with an excess of N2 gas at 200 atm and 500 degrees C, how many moles of ammonia gas would be produced, assuming a 15% yield?
A 98 L sample of dry air cools from 138°C to -30.°C while the pressure is maintained at 2.85 atm. What is the final volume?
A mixture containing 2.37 g each of CH4(g), C2H4(g) and C4H10(g) is contained in a 1.50 L flask at a temperature of 45°C.
A saturated solution of Pb(IO3)2 in pure water has a lead ion concentration of 5.0 x 10-5 Molar. What is the Ksp value of Pb(IO3)2?
In this experiment a hot metal block at 100oC is added to cold water in a calorimeter. The heat lost by the metal block equals the heat gained by the water and the two end up at the same temperature.
the density of aluminum is 2.7 g/cm cubed, if the volume of this object is 12ml, what is the mass of the grams?
