Gabrielle M. 8 years ago I'm working on Chemical Reactions: Double and Single Replacement on FLVS. Now my first question for this video is, how do you have 4 aluminum atoms when it says 2Al subscript 2? Do you just add the 2 and the subscript 2? Same thing goes with the O3. I am so lost.

When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky. When N H4OH solution is added to the above mixture (after adding dilute HCl ), it produces a white precipitate which is soluble in excess N H4OH solution.

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
