First ... I got to say "Thank You" for taking your time to add youtube content for Chevrolet Spark (2016-2022) owners. If I have another brand of cabin air filter (mine is Hann & Co, if I remember well)... Mine has a green side and a grey almost white side, How do I Know which side to put up ???

What is that R^2=1 in the graph (@6:58 ) indicates?

@physicalchemistry_pchem 12 күн бұрын

R^2=1 indicates perfect fitting. When R^2 = 0, there is no correlation.

06:23 There are only four quantum numbers. You have written fifth. How it can be possible?

@physicalchemistry_pchem 27 күн бұрын

The "s" quantum number is not often taught in general chemistry because s=1/2 for every electron. But this quantum number is taught in inorganic or quantum chemistry. "m_s" is to "s" as "m_l" to "l".

Good one. I have query that how to find ground state energy of any molecule with excellent accuracy? Is SPE is nothing but ground state energy? Can you please clarify? Thanks @physicalchemistry_pchem

@physicalchemistry_pchem 3 ай бұрын

The single-point energy is the electronic energy + the nucleus-nucleus repulsion calculated at the given atomic structure (usually from the user's input). The electronic energy is the sum of the kinetic energy of the electrons, the electron-electron repulsion, and the nucleus-electron attraction. If you aim to get the ground state energy (assuming at the equilibrium structure), a geometry optimization calculation must be carried out.

Thank you so much for the video. It only took a minute or so to replace the blade after watching it. I see you can buy an official Subaru replacement blade online directly from Subaru-- Replaces Part Number: 86548XA09A, 86542AG09A, SOA591U314R, SOA591R514, 86542AG080 currently $11.50. That is a safe purchase! Walmart has it for the same price online but a review indicated an installation problem "This sensor does NOT have the connector included - it needs to be CUT and SPLICED. No where in the description does it mention that fact!! I would never cut and splice one of these units - it opens the door for more problems down the line and more than likely need replacing - especially being exposed to water and weather under the vehicle."

@sebanthomas9361 7 ай бұрын

sir , does the addition of another species would increase entropy of the system (randomness) thereby increasing the slope du/dt valve?

@physicalchemistry_pchem 7 ай бұрын

Yes, the slope would be more negative in this case. Good point!

how did you calculate the eutectic point from the data?

@physicalchemistry_pchem 7 ай бұрын

For example, assuming that the enthalpy of fusion of two chemicals A and B are 25 and 35 kJ/mol, respectively, and that the melting points of these two pure chemicals are 420 and 480 K, respectively, you may type up the following request on the Wolfram Alpha page: Solve e^(25000/8.31446*(1/420-β))+e^(35000/8.31446*(1/480-β))=1 The result is β = 0.00245793 T_eutectic=(1 K)/β=(1 K)/0.00245793=406.846 K=407 K

Typical drain cleaner or clog remover contains only ~1% NaOH by mass, while we are using ~10% in the video. Kitchen granules or crystal lye drain opener contains 60-100% NaOH.

Hey sir , can I ask something about C-O bond length? Can we confirm [MnCo5(PF3)3 and [MnCo5(PPh3)3 ] complexes, what should will be expected to longer C-O bond . I know PF3 greater Pi acceptor and back bonding but I don’t know that the confirm these complexes about their length . Thanks for answer sir

@physicalchemistry_pchem 9 ай бұрын

The formulas look weird. Any typos? In general, when the transition metal center donates its d electrons to the pi* antibonding orbital of a CO ligand, it reduces the CO bond order and makes the CO bond longer. Now, I will let you compare PF3 and PPh3 yourself in their abilities to withdraw electrons from or donate electrons to the transition metal.

Transition Metal Complexation. Pi electrons of the alkene flow into the empty d orbitals of Rh; d electrons of Rh slows into the pi* antibonding orbital of the alkene.

Thank you for this video I had a flawless install. Once the hook is on you have to pull up hard until it clicks down into position then you flip the little plastic flap. If the j hook is not down all the way the flap wont close.
