When a container is filled with 3.00 moles of h2, 2.00 moles of o2, and 1.00 mole of n2, the pressure in the container is 768 kpa. what is the partial pressure of o2? 154 kpa 192 kpa 128 kpa 256 kpa

The  partial  pressure  of O2=  256 kpa

       calculation

                    that is 3.00 moles +  2.00 moles +  1.00  moles =  6 .00  moles

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
