What is the driving force of the deep water ocean conveyor belt? -Winds push the deep water into the Pacific and Indian Oceans.

-Gravity from the Moon pulls the deep water toward the equator.

-The spinning of Earth makes the deep water current run in circular paths.

-Very cold temperatures create very dense water which pushes the deep current along.

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 :

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
