Which statement best describes the ocean floor?

It is mostly covered with undersea mountain ranges.

It is mostly flat, with little distinguishing features.

It is varied and includes mostly undersea volcanoes and seamounts.

It is varied and includes features such as submarine canyons, atolls, and mid-ocean ridges.

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 :
