Harley mixes a cup of sugar and a cup of salt together inside a large bowl. the sugar and salt form a mixture and do not chemically combine. the solid grains in the mixture are made of tiny particles of matter. which of the following conclusions can be made about these particles? a. the salt particles are different from the sugar particles. b. the particles of sugar in the sugar grains are all identical. c. the particles of salt in the salt grains are all identical. d. all of these

It is all of the above. :D

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 :
