When adding electrons, the charge becomes positive.
When adding electrons, the charge becomes negative.
When subtracting electrons, the charge becomes positive.
When subtracting electrons, the charge becomes negative.
Lose of electrons makes the atoms smaller.
Lose of electrons makes the atoms larger.
Gain of electrons makes the atoms smaller
Gain of electrons makes the atoms larger.

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 :

your answer would be “dry”
