Explain in detail what causes the color to change when testing different elements in a gas tube or under a flame. Explain what is happening to the electrons specifically that causes the color/light we see.

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

Which is an example of a highly unstable isotope that is often used in fission reactions?

Witch two conditions can limit the usefulness of the kinetic molecular theory in describing gas behavior?
