I have an exam tomorrow. It would've been REAL helpful if you'd show the mathematical working in your videos. Literally non of them have it. Some of us suck at the math stuff. Thats why we look up videos to see the working. If I wanted to see the answer I could just read the mark scheme (:
i feel she actually does work through how or why the answers are what they are. but she does it very succintly, and without too much elaboration. because i think it simplifies things to assume the student watching already understands the theory but just wants to see how it relates to the specific question.
How come the SO2 you drew had 2 double bonds instead of 1.I’ve seen alot of other videos about this and they say it should be 1 single S-O bond and 1 double S=O bond which fits the octette rule, but the marking scheme does it your way.Pls help
After you put lone pairs on oxygen and sulfur atoms, check the stability and make the structure most stable by minimising charges on each atom. You can convert lone pairs to bond pairs to stabilise a structure and that's how you achieve this structure with center Sulfur atom bonded to two oxygen atoms each having a double bond.
19:59 ,The sound of the bird is so soothing ,Also the teacher has got great skills to make me understand everthing with a blink of an eye. Where do you teach ,i want to join .
Talking from a friend's standpoint, both share the same degree of difficulty though Edexcel allows you to retake individual units incase of unsatisfactory grade, unlike Cambridge where you will have to retake an entire session (meaning all components).

Totally agreee

question number 3 is very important.. almost a summary of periodicity
Ur videos are really helpful highly appreciated ❤️
maybe you are great explaining and solving in 30 minutes
Why did you multiply SO2 by 4 when the equation had only 2 moles in question 1 b part?
Basically there are two S=O bonds hence the x2, and since it’s 2 moles, so another x2 multiplied which equals x4 in total

Thank you for your comment. We do not do formal teaching anywhere. Our website and RUclips channel is the only place where we upload our content.
Can u plz tell where did -196 come from
If you read the question, the info before part a(i), the eq tells you about the total enthalpy change
Which as level maths is easy Cambridge or edexcel?

so how did your exam go?
how did your exam go?@@wamiqmain409
appreciate the work but please stop the accent it physically hu8rts
you should explain more in detail
We will sure. Feel free to ask any particular questions you want us to give an elaborate explanation for.
