How did the work of Dmitri Mendeleev differ from that of John Newlands in the development of the periodic table? Mendeleev arranged the elements according to increasing atomic mass.
Mendeleev predicted elements that would later be discovered.
Mendeleev identified elements that had similar properties.
Mendeleev organized elements into triads based on their properties.

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 :
