Suppose you have equal amounts of three substances labeled a, b, and c. then you add 350 ml of water to each, and then wait so that each one has time to absorb all of the water that it can. 25 ml of surface water remains above substance a. 60 ml of surface water remains above substance b. no water remains above substance c. which of the substances has the greatest porosity? Substance A
Substance B
Substance C
There is not enough information to determine this

Explanation:

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 :
