For the reaction SO2(g) + NO2(g) ⇔ NO(g) + SO3(g) has K = 85.0.
What will be the equilibrium concentrations of the four gases if a mixture of SO2 and NO2 is prepared in which they both have initial concentrations of 0.075 M ?

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

the dissolution of polymer can be thermodynamically described in 2 steps.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
