Explain the science of water pressure

"At sea level, the air that surrounds us presses down on our bodies at 14.7 pounds per square inch . (gooxgle) "

Basically the deeper you go under the water, whether that be a pool or the sea the pressure will increase because of the weight of the water above you.  Which causes greater force.

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 :
