Explanation:

The thicker the horizons, the older the soil. The more difference there is between adjacent horizons, the older the soil. Determined by the amount of weathering that has occurred; to what extent the parent material has been converted to distinct horizons or soil layers.

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 :
