hi ma'am! i abolutely love how you explain things! just wondering if you have any videos about transition metals, benzenes and nitrogen compounds? if not, that's completely fine! thank u in advanced :))

Hi Dearlantsov! I have a few benzene (aromatic) videos and one nitration video in my “organic” playlist. I don’t have any in transition metal videos. Here is the link to the playlist. Scroll toward the bottom. I hope this helps! Thanks!😊 kzread.info/head/PL0xN_H1gE3Vfi8kbhj35C5K7VxC02_DmN

100mL of a solution contained 3.2g of potassium nitrate. 25mL of this solution was added to an empty 250mL volumetric flask. Distilled water was added up to the 250mL mark and the flask was shaken to ensure that mixing was complete. A pipette was used to transfer 25mL of the resulting solution from the volumetric flask to an empty conical flask. What is the concentration of the potassium nitrate solution, in g L-1, in the conical flask? can u explain why the answer here is 3.2, even tho we diluted it more?

Hi Yousef, the final solution is definitely diluted and a lower concentration than the original solution. I hope that helps! Thanks😊

Hi !! I love your explanation very plain , simple and easy to understand. Btw, Have you seen the Chemistry question paper of JEE Advanced this year ?? I'm sure you would enjoy that too 😃. The paper 1 was filled with beautiful Physical Chemistry questions. Do check that out 😊

Hi AB, thank you for the information. I will have to look. Thank you!!

Hi. In the reaction when water ionises H2O-->(H+) + (OH-) Why is the OH- and H+ concentration constant between the 0 and 100 temperature?? Here i thought of it as the temperature changes the equallibrium changes which means that the ratio of products and reactants will change so the products concentration is very likely to change, but it turns out that this is wrong and the H+ and OH- concentration is constant with temperature change?? Can u explain that please?!

Hi Joe, because it reaches equilibrium (most energetically favorable state) which is 1x10^14 equilibrium constant. I hope that helps:)

It is true for all equilibrium reactions. Thanks!

Really sad to see a chemistry teacher with such low views ....i m confused... like don't the english speaking countries study Chemistry...or india is the only country where Chemistry is taught ...u deserve more views..idk any idea but maybe the english speaking country people are no more interested in chemistry...
