QUESTION 3 The 1H signal NMR corresponding to the hydrogen atoms on position d are more downfield than the 1H NMR signal that corresponds to the hydrogen atoms on position c. (1 pt) True False

True

Explanation:

1H NMR represents Proton Nuclear Magnetic resonance. It is the application of magnetic resonance with 1 hydrogen atom. The hydrogen molecule is reacted with the corresponding atom nuclei to generate signals and then hydrogen atoms move downfield.

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 :
