At 25 degrees Celsius, what is the hydroxide ion concentration [OH-], in an aqueous solution with a hydrogen ion concentration of [H+]= 2.10 x 10-3

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 :

let that person have a turn to speak : )

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
