Which describes an ice age? a. the time when woolly mammoths and other extinct animals walked earths surface. b. the periodic freezing of the oceans, occurring once every 100,000 years. c. cold periods in earths history during which glaciers covered much of the surface. d. a year of cooler than usual summer months.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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 :

can you list the answers so i can answer
