We put 10.0 moles of N2O into a 2.0 L container at some temperature. At equilibrium, 2.20 moles of N2 remain. Calculate the equilibrium constant, Kc, for the reaction at this temperature. 2N2O(g) "yields" 2N2(g) + O2(g)

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

answerca air mass;
