Chemical equations need to be balanced in order to satisfy the law of conservation of matter, which states that in a closed system matter is neither created nor destroyed. Explanation: Take for example the combustion of methane ( CH4 ): CH4 + O2 → CO2 + H2O

Maxwell’s relations can be derived as: d U = T d S − P d V (differential form of internal energy) d U = ( ∂ z ∂ x) y d x + ( ∂ z ∂ y) x d y (total differential form) d z = M d x + N d y (another way of showing the equation) M = ( ∂ z ∂ x) y and N = ( ∂ z ∂ y) x From d U = T d S − P d V T = ( ∂ U ∂ S) V and − P = ( ∂ U ∂ V) S
