One of the most important aspects of a periodic table is that it select one: a. makes use of all of the letters of the alphabet. b. brings order to the elements. c. predicts all of the future elements that have not been discovered. d. separates matter from anti-matter.

did anyone actually do this? like if anyone has submitted this i rly need .

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 :
