Writing Formulas from Names (1 of 2)

[@lyssaboo1513]

I think this video is most helpful when you pause before he reveals the answer to write down your answer and then check to see if you were correct or where you did wrong. I did it like that and memorized a lot of names along the way.

bakwas

[@Star-ym4bg]

Hmm valo

[@123okubo]

@@dikshayadav1073 how? tell me any 1 reason why it is "bakwas"?

[@itiswhatitisvato]

But how do you find out what the formula for hydroxide, pentoxide, sulfate, or even ammonium?? For ex. how do you get the "NH4" for Ammonium??

[@kashmindalal1662]

Those are polyatomic ions, those you just have to memorize.

[@inforthekiii8840]

not necessarily, you'll be given a chart of polyatomic ions along with periodic tables if you're being taught about this stuff early in your year. but you will have to memorize it in your final exams later on in your year

Thanks! :) Do you use Study Blue? What study tips can you give us? Thanks in advance!

[@mirandawheeler8495]

Extremely helpful! Thank you for posting.

[@beverlypenasco5927]

You should also do Zinc Flouride... and I was also wondering .. how do you figure out how many atoms you need to balance out the other element?

Hi sir magnetic repel function chemical name

[@sea5205]

This was really helpful, thanks!

[@shivsahu4670]

Thanks sir It is very useful for me

[@waisaman1129]

excuse me sir but its covalent compound not molecuLAR COMPOUND SINCE DINITROGEN PENTAOXIDE

[@reverbflange]

SO^-2 is sulfate... it's a polyatomic ion. S by it's self is sulfur, therefore CaS would be calcium sulphide, while CaSO is calcium sulfate :)

[@jaimearredondo787]

reverbflange CaSO4 is calcium sulfate

[@jaimearredondo787]

Calcium sulfide (CaS) yes but it’s sulfide

[@dilipkushwaha7303]

very helpful and useful

[@samanthageorge6891]

I got a test an u not making this shit easy

[@Mosimanegape21]

Thanks for this video, it really make sense. Can you please explain the difference between the sulfate and sulfite ( Beryllium sulfite and calcium sulfate). I am confused , could you make it understandable for me please?.

[@sara17007]

Isn't Calcium Sulfate = Ca and S ? Where did the O - behind S come from? I think your video's are great! :)

[@AndrejNikolov-xw2gi]

It's correct. CaSO4... Sulfate = SO4 Sulfide = SO3

[@Mattiohead1]

thanks for the help!

[@karenmonroe5873]

why didnt i find this before my chemistry test!?

[@BanellaRg]

very difficult :(

[@chetowfg7338]

What I'm doing here🤔

[@golfgirl909]

Confusing. please slow down
