There has been a major breakthrough, element 149, CPhsium has been synthesized. We must know its electron configuration. Add another row to the periodic table and follow the filling order you have learned to write a noble gas configuration for CPhsium.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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 :
