Calculate the H for the reaction NO (g) -> 1/2N 2(g) + 1/2O 2(g)
Given the following information:
1/2N 2(g) + O 2(g) -> NO 2(g) H = +33.8 kJ/mol
NO (g) + 1/2O 2(g) -> NO 2(g) H = -56.6 kJ/mol

How do scientists think that gravity affected the formation of our solar system?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
