In lab, you will experiment with three solutions ‒ di water, ethanol, and 4m cacl2 ‒ to develop a method to separate 6 types of plastic. what ideas do you have about possible methods to separate the plastics using these solutions? how could you change the densities of the solutions that are provided? how could you group the types of plastics to work out a separation method?

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 :

give me abc and i will get it for u.
