Using a 500cm3 flask what mass of pure NaOH do we add to make a 0.2 moles solution?​

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

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 :

just did the assignment and the answer was #1 +2 n
