Recall what you learned about the state of Virginia. Choose the statements that describe the paleontology of the state. Check all that apply. The rocks in Virginia represent many periods in history.
Virginia was once covered by a sea.
Virginia’s fossils include woolly mammoths.
The Allegheny Plateau includes coal deposits.
Virginia is home to fossils that are mostly from the Cenozoic era.
The state’s climate was once warm and humid, like a tropical jungle.

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 :

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
