What mass of melamine, C3N3(NH2)3, will be obtained from 157.0 kg of urea, CO(NH2)2, if the yield of the overall reaction is 74.0 %% ?

b) mutualism

hope this : )

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

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 :
