Chem Tutorial: Formula Writing and Naming

[@samcha1718]

His voice gave me energy more than my coffee.HAHAHAHA

[@rinyuuki1487]

Thank you! I was lagging behind in my class, I really needed this!! Thanks! You saved me!

[@amysorensen7605]

you just taught me what my chemistry teacher failed to teach me in 6 1 1/2 hour classes in 22 minutes thank you

@mysstring1 The standard for formula writing dictates that the positive ion be written first and the negative ion be written second so as to avoid confusion. In addition, metal atoms are ALWAYS + charged and nonmetals will consequently be - charged when bonded to a metal.

[@MarkRosengarten]

@mysstring1 The sulfur is the central atom and four oxygen atoms bond around it. The resulting particle has an excess of electrons, leading to a net 2- charge through what's called "coordinate covalent bonding".

[@MarkRosengarten]

@mysstring1 No. Chlorite has a 1- charge, with the Cl having a 1+ oxidation state and the O having a 2- oxidation state.

Awesome video!! I couldn't find any helpful video I was getting frustrated until I came up across yours!! Easy yet very informative thank you so much!!

[@mysstring1]

I was really confused with the idea of polyatomic ions, in ur powerpoint, it was said to have an unbalanced net charge or "broken" molecules, does the molecule suggest that polyatomic ions are COVALENT compound? what caused such imbalance in net charge to occur?ie. why there is always a 2- charge after SO4? what's the chemical explaination behind it?

[@mysstring1]

hihi~ can I ask something> when you use the reverse crossover technique to work out what the original charges were for each element that make up the compound, how do you know that the first one is + x, the second charge is -y?

[@mysstring1]

with one of examples up there,: Cu(ClO), can't the answer be copper (II) chlorite , with the 2- charge cancelling out the 2+ charge on copper , instead of Copper hypochlorite?

I wish you were my Chem teacher u talented and have a flair

[@josephasinchang]

Do you have the powerpoint available for download anywhere?

[@rjravaz]

besides lcm for an emprical formula how can you tell when a formula is Emprical?

[@takoyaki6332]

Ill give an example AI+3. O-2 It will ve AI2 and O3 The name will be Aluminum oxide. Is this true? What type of formula is this?

[@jacobnothin1021]

Look this up in your friendly neighborhood periodic table hahaha. For a moment i thought he would say friendly neighborhood spiderman LOL

[@juvellebarrogo4969]

It really helped me a lot! Excellent. Thank you!

[@nick-8759]

Great video nice and simple really helped a lot

[@ankineedukavuri8634]

It may be better to write the names of the compound at right side of each లైన్.

[@Sanjchin]

Thanks a lot i understand very well

[@rjravaz]

such a great video! Thank you for you help.

[@emsnts1125]

This is definitely helpful. Thank you so much!

[@kylagaylesantianez2080]

THANK YOU, THANK YOU VERY MUCH.. :) Tomorrow, i won't be staring at the wall during the exam..

[@kimberlyhaugan9983]

Why does this make sense now after 29 years

[@MarkRosengarten]

@josephasinchang Too large to upload. :(

[@jessrreese]

THANK YOU!!!!

[@rredcheezy]

OMG...thank you soso muchh

[@zeannejoylabadia222]

Wow thank you

[@KeaJei]

thank you so much!

[@user-ls6uw4jp7x]

how do I know how to write zinc phosphate?

[@kylecarlos3415]

Zn3P8 note that the two numbers are subscripts... the superscript of Zn should be multiplied to the subscript of P

thank you..
