¿ cuál es la importancia de conocer las propiedades físicas y químicas de los materiales ?​

Porque se requiere de conocer su masa, su densidad y otras cosas más para solo entender y aplicar las fórmulas, se requería para conocer cómo se comporta la materia en determinadas condiciones.

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 :
