In a bag there are 72 candy bars , 40 of them are are snickers,24 of them are mikly ways, and the rest are kit kats.

8 kit kats

Explanation:

I assume you asking how many kit kats there are.  If thats the case, then the answer is 8 kit kats.

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 :
