Dissolve 8 grams of weak HX acid in 4 liters of pure water at 25 degrees. Calculate the pH of the solution if the volume of the solution is neglected and the ionization percentage is 2%.

answer; i believe the correct answer is (solid gold);

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 :

c. orbital shape i hope this is correct

the objects have the same charge.
