Looking up one snowy afternoon from a book titled The Moral Case Against Turning Lead Into Gold (Or Vice Versa), your friend Christine (an expert chemist) says this: Ammonium salts heated with aqueous hydroxides form ammonia, water, and a salt. Using Christines statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced!

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

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 :
