Naming Compounds from Formulas (1 of 3)

[@AForkSpoon]

Better teacher than my professor.

[@torinvanderpool1900]

Nevermind!! I found the polyatomic ion chart in my book. Thanks, great vid!

[@sean_tristan31]

SIR! how did u get Titanium (IV) oxide in TiO2? i dont seem to understand this in my chemistry classes. please help :))

[@chemhelps]

Remember that the oxide ion has a 2- charge. Since there are two of them, it is a 4- charge that must be balanced out by the titanium. Also, note that it is not titanium dioxide because it is a combination of a metal with a nonmetal, which makes it ionic, but only molecular compounds (those made from two nonmetals) are named using the prefixes (di, tri, etc.). (That said, in the real world, you will often see it labeled as titanium dioxide, but this deviates from the standard naming practices.)

I could watch this 278384 times and I'm still gonna fail my test ☕️🐸

Katherine Molina 9901991110 my contact giv. me ur cotact num

[@Aaronhi]

I have a question. Why is Cu3(PO4)2, Copper (l) Phosphate and not copper (lll)?

[@chemhelps]

Don't forget you have two Copper ions to divide that 2+ charge over. That is why it is Copper (I)... There are two of them to balance the 2- of the oxygen, while it would only take one Copper (II) ion, so Copper (II) oxide is CuO, while Copper (I) oxide is Cu2O.

[@torinvanderpool1900]

for the first one how are you supposed to know that CO3 is carbonate?? is that memorized material?

[@olivia58909]

THANKYOU hopefully ill pass my test tomorrow!!

[@HoneySingh-rb4cw]

I'm sorry but i coudn't understand when to use suffix 'ide' or 'ite' or 'ate'..And when to specify the charge.. E.g- CO3 is carbonate not carbonite..How will i know it.. Plss help

[@alisonchuang8595]

Thank you so much! I finally understand how to do this :)

[@sirsilversaibur]

why did just start writing roman numerals ah i'm very screwed for my exam

[@12yoweaboo]

James Ranger did u pasd

[@jacklindsay4088]

its because we dont know the charges for transition elements. Therefore to balance the equation we must know the charge of the other element/compound. The charge for Oxygen is -2, and in the TiO2 compound, its charge will then be -4 because there is 2 oxygen atoms. Therefore for it to be balanced, titanium's charge must be 4, hence the written equation of Titanium (IV) Oxide.

[@danielmusa9001]

Hi pls I need your help on this.what is the mass of 0.05mole of chlorin (molar mass of cl =35.5

[@joellado6525]

Daniel Musa 0.05x 1 divided by 6.022x10^23 power.

[@jordandarst3632]

This guy that gave you an answer doesn't have a clue as to what hes talking about. He seen moles and just threw out Avogadro's number lol. You just need to memorize the formula Mass= Molar mass x number of moles. So you need to multiply 0.05m times 35.5g/mol. Its that easy.

[@4dv4rch3r]

Thank you this was very helpful!

[@naimaaf1]

Thank you so much. I wish my teacher can explain it like this. :-) +++

[@poppr82]

how did you know it was titanium (IV)?? I don't get how you got that just from 2 >_

[@handledishandle]

Hello sir, the Ti is located in the IVB group, it is not in the first or the second group like Ca or K, if the metal is located in the B group like the Ti is, that means, you have to calculate it's charge from the other ingredient which is the O2 in this situation, O itself has a charge of -2, but you got 2 O's so it will have a charge of 2*-2 which equals -4, so the Titanium must have a charge of 4 so it would be balanced. If you got a B group metal and a non-metal you do the roman numeral to the middle of the name of the compound.

[@ziakhan5538]

From oxidation number you need to first find out the oxidation number and then include it after the element name

[@forever27101]

but i thought you were supposed to neutralize the equation, why is it that in some other equations its 2. like eg: Sn 4+ 2+ and O2- and the answer is tin (II) oxide, that makes sense because 2+ (-2) equals 0 sorry its Cu 2+ 1+ and O 2- woops lol

[@sean_tristan31]

Thank you sir! :) helped me a lot.

[@carsonschumann9311]

Thank you🙏🏻

[@Saltyunicorns]

5:14 is my fav part

[@kaziamoua261]

Josh Chew why??

[@Saltyunicorns]

@@kaziamoua261 cause he explains it well

[@kaziamoua261]

Josh Chew oh ok

[@starleftearth]

thank you !!

[@forever27101]

so im doing this work sheet and they give you the formula and you have to give the name. So i went and looked at the answers online and go confused with this one. So its Cu2O (pretend that 2 is small and at the bottom) and the answer is copper (I) oxide. i broke the equation down and got Cu 2+ and O 2- . 1+ wouldnt it be copper (II) oxide? 2 balences out the equation!!! at least thats pretty much how it is for the majority. HELP!!

[@sreepam9480]

Hey I'm doing the exact same thing rn. Do u have 228 questions?

[@LeBrowine]

Because you cross the charges of PO4 and Cu3

[@bwilliams1834]

i was absent for 2 days and i was confused when i came back then i realized i didn't have the list of polyatomic ions my teacher gave the class XD

[@dominickarany7581]

he makes it look so easy :'(

[@chemhelps]

@LinkingFatez: lol. Sorry, but I'm already happily married. :)

[@longelevenandahalfdong9586]

Sir I like how you just assume someone will know carbon and oxygen will be call "carbonate" a brief 5 second explanation would have helped.

[@angelswati8852]

To understand this first u have to learn the chemical names with their formula then automatically u will understand this... 😂😂

[@MrSamwiseable]

clip your nails!!!
