What do you think thr accuracy is of this for measuring current?
Depends on the multimeter - this was a $10 multimeter so I'm assuming it will be within 10-20% of the true value. Nicer multimeters will be much more precise, as specified by their datasheets (which list their capabilities). Your cables will also affect the precision in a manner that is hard to predict, so if it feels "wiggly" then your precision will suffer.
Thank you very much sir😅
Amazingly explained. Thank you
Awesome videos! Really helped me understand difficult concepts! Cheers!
Thank you so much!
thank you so much!
This video improved my learning around this concept at the highest level!
Thank you so so much Professor!! Your videos are so structured and easy to follow.
👍
You're awesome
🎯 Key Takeaways for quick navigation: 00:29 *🧪 Equilibrium constant for a reaction with stoichiometric coefficients involves squaring products and placing reactants in the denominator.* 00:58 *📊 Ideal gas law helps relate concentration to pressure, making it more convenient for calculations.* 01:54 *🔄 Exponent in equilibrium constant depends on the moles of gas involved, using Delta n (final moles - initial moles).* 02:36 *📈 Pressure equilibrium constant (Kp) is related to concentration equilibrium constant (Kc) by Kp = Kc * RT^Δn.* 03:30 *🧩 Delta nu gas is introduced as a term in equilibrium calculations, similar to Delta n but represented differently.* 04:55 *🔄 Converting Kc to Kp involves using the ideal gas law constant and considering Delta n (moles of product gases - moles of reactant gases).* Made with HARPA AI
An actual worked example ∆o=E=etc .. would help drive the point home
Thank you ❤️
Great video, but one correction for the tetrahedral crystal field splitting diagram is that g and u labels don't apply here (the groups are t2 and u only) because a tetrahedron has no inversion center. I often forget this when teaching it as well.
Thanks that’s really help a lot for my assignment
Bro, loved this video exactly what my intro to analytical course covers. Loved how weird and strateforward you are
Thank you 💕💕
Good day Sir! what's your reference? Is it from a book? Thank youu for your response. Anyway, big thanks to your videos. It helped me in my Chemistry Lab.
10:15 are they not superimposable if you just rotate 90 degrees the other way around?
That’s the point he’s trying to make right. No matter how u spin them, enantiomers are enantiomers. They can never be superimposed even though you rotate. Super impose means to overlap perfectly or simply, they are congruent or exactly the same object in dimensions. In general (not chemistry) if you mirrored a *symmetrical* object and rotated it, you *can superimpose* it. However if you take an *unsymmetrical* or *chiral object and rotated it about any axis you like however you try, then you can *never ever superimpose it* with In the video, Fe(en)2Cl2. When he rotates the compound, look the mirrored + rotated compound (the third one) and the previous compound (the first one), 😅notice the similarities:- 1) The central atom (Iron) 2) The chlorine ligand situated above the horizontal square plane or simply the top vertex of the octahedron 3) The diethyl amine ligand bonding with the iron in the same way and orientation in both compounds which is situated at the bottom right edge of the octahedron (it does of course tends to come out of the octahedron but to keep it simple, both are same). The above things *can be superimposed with each other* because they are exactly in the same position with respect to the central iron atom Now, notice the differences:- 1) The plane in the first compound consists of diethyl amine on the left side but the the plane of the third compound consists of the diethyl amine more like into the screen/plane/paper/negative Z axis or whatever u like. 2) The chlorine in the plane of both compounds is situated at different locations as well The above things discussed now, cannot be *superimposed* As observed till now, we can notice that the central atom(Iron) and two of the ligands(the ligands *non co-planar* ones or the ones situated on and below the plane) *can be super imposed perfectly* and two of them (the *co-planar* ones) are off and *can’t be super imposed*, we can finally conclude that the *complex on the whole, cannot be superimposed* though it is rotated I tried my best to explain this. I hope you understand.
Hope this helps 😊😊😊
Hi, great vid but I have a question. Where did you get the F table value of 5.820 (at 22:40min, when you are solving a practical problem for the F test)? I looked at your F table found at 11:54min, and I see value of 4.28 for two methods each with 6 degrees of freedom and within 95% agreement. Am I missing something? Thanks, in advance.
Thank you very much
The new mole of base must not be equal to 0.4 coz the system not yet undergo equilibrium
Very informative
Thanks, Mark 😁😁😁😁😁😁😁😁😁😁😐😐😐😐😐😐😐😐😐😐😐🤨🤨🤨🤨🤨🤨🤨🤨🤨🤨🤨🤭🤭🤭😗😗😗😗😗😗😗😗😗🤭🤭🤭🤭🤭🤭🤭🤭🤭
i dont know what i need it for but thanks for explanation❤
Fantastic video! Thank you so much!
I love you man
Hee hawwww henderson buckle equation baby let’s goooo get it cowboys let’s go gnarly dude mother trucker mannnnnnn
you sound like john cena
you helped me survive my inorganic chem class. thank you for your contribution
amazingg where r u from
Very helpful, thank you!
amazing teacher and fine work. please tell me the book you are teaching
Thank you! We follow McQuarrie's General Chemistry
wonderful videos are ever seen. and the teaching method is so good. Please tell me which book you are following.
Thank you! We follow McQuarrie's General Chemistry, but this video is probably a mashup of the various books I've used when teaching chem.
Extremely underrated,u deserve 200% more recognition, awesome explanations sir!! 🎉 🎉 🎉 ❤
Please make videos on bioanalytical method deveyon human plasma by internal std spiking method.
Thank you,Great explaination.
saved my degree
GREAT VIDEO! SUBSCRIBED!
شرح مبسط ممكن
great vid i hate chem
Great explanation!
How do you know that you will need this number ligand to bond with central cation
At the general chemistry level we'll either tell you how many ligands bond with the central atom or we'll provide you with simple rules (in my class I just tell students how many ligands there are, or make it known via chemical formula or name).
@@marklingwood7811 thought which chemical formula
Please when balanceing redox reaction will you be informed about the medium in which you are balance or you have to know
ur a mf g
Great vid! Thanks 👍
Awesome!!
Thank you so much for making this easier to understand!
Great video! You explain things very clearly and it's easy to follow.
