HI, this helped a lot and this really helped. I am a 7th grader taking a test on this exact stuff on thursday. Thank you so much for your great videos.
for 11:07 after writing snso4+ Fecl3 how come u didnt write sn2 becasue sulfatre has a charge of 2 and not write (so4)2 do u not criss cross the charges? or jsut blance them please help me
My chem teacher is Indian and he doesn't know how to speak English very well and it's thru online 😭 I'm so frustrated so here i am trying to watch every RUclips video that exists
how do you know copper on the second to last is +2 or just +1??? because first you said +1 and then when you wrote it you said +2. :/ i understand how to figure it out when theres a compound and it gives it away, but I'm confused with this one.
the iron chloride (iii) with calcium sulfate example is wrong. it should have been 4FeCl3+3Ca2(So4)2 ---->2 Fe2(So4)3 + 6CaCl2 because the sulfate (polyatomic ion) has a -2 charge and Ca ion has a +2 charge . I have balanced it as well in case you want to know
Ok so copper and nitrate were together. We had to find out the carge of cu, but we already new the charge of nitrate which was -1. There were two nitrates so the charge would be -2. And to make both parts equal then cu had to b positive 2. That way it would b positive 2, which was copper, and negative 2, which was the two nitrates together. Hoped that helped
Iron can either be Fe2+ or Fe3+, however, when predicting chemical equations, it is suggested that you use the lowest charge, which would be Fe2+. Not quite sure why he used Fe3+, and I assume it would be up to your specific teacher whether this in incorrect or not.
It is shown in the brackets as Iron (III) as a way of showing the charge just like how Tin ,Pb, has a (II) after it to show it has a +2 charge because bothe Iron and Tin have different charges
2:19 - A little mistake, because Fe has to be 2+ But if you choose 3+, then you have to equal amount of Cl, Fe and Cu on each side. This means that you have to have this: 2 Fe3+ + 3 CuCl2 ------> 2 FeCl3 + 3 Cu2+ Have a good day :-)
You can a best guess. For this level of chemistry, I stick to 5 types: Composition, Decomposition, Single Replacement, Double Replacement and Combustion. We don't try to predict products for the exceptions or for anything that is not one of these 5.
+Marc Seigel OK Marc thanks for the comment, just curious on how well you do that. I have to present software and I am looking into the ability to write while presenting. When you can do that, it adds value to the presentation as onlookers can see your thinking more clearly.
Hey all! I reckon the iron chloride (iii) with calcium sulfate example is wrong. it should have been 4FeCl3+3Ca2(So4)2 ------>2 Fe2(So4)3 + 6CaCl2 because the sulfate (polyatomic ion) has a -2 charge and Ca ion has a +2 charge .
Someone tell me why I learned more in this 11 minute youtube video than I did in 4 hours of a college course? I think I must have the worst teacher ever...
Someone please answer! Why do you get Fe3OH in the second problem where he pauses the video? Mg(NO3)2+Fe3OH. I thought Fe was a transition metal and had no charge, so for my answer I got Mg(NO)3+FeOH???
Because over here the valency of iron is 3 and that of hydroxide is 1- so they switch and hence becomes Fe1-OH3 which will be written as Fe(OH)3, OH is in the bracket because only hydroxide is meant to be 3 and not iron because it is one and so we write OH in the bracket.
There are 2 oxidation states for Fe. One is +3 and the other is +2. It will all depend on how the Iron is stated. If it's Ferric, it's Fe+3. If it's Ferrous, it's Fe+2. Typically, most of the p, d and f orbitals have 2 or more oxidation states. Fe is one of them.
you probably had your test already but if you didnt, you can see which elements have a negative charge and which have a positive charge on your periodic table. you can just do a simple search up on google like like "trend for ionic charge on periodic table" each period has a different charge
Settle Down Prostitutes well when you get into high school there are 3 other SR formulas 2 other synthesis formulas 1 more DR formula and 5 other decomposition formulas (10th)
@@jonkrade6644 oh man that was 5 years ago when I was a sophomore in high school haha. I am now a junior in college and am actually receiving a minor in analytical chemistry! I strongly recommend Melissa Maribel, Tyler Dewitt, and the Organic Chemistry Tutor on here if you find that you are still struggling with general chemistry, they helped me understand SO much! Good luck!
I have learned more in your 11 minute video than 2 hours in my class. Thank you.
loveforbooks e ME TOO
All teachers care about is the grades. These guys don't even get paid to do this, and they care.
It’s crazy how much better you are at teaching this in a RUclips video than my IB Teacher. Thank you!
This video was published in 2012 and I am watching it in 2021. It was really really helpful than my class. Thank you so much !!
Holyy..
From my grade 8 now 12 , until now, never understood this
thanks homie. my teacher dont know how to teach, and this video actually made me understand this stuff. and for that, you get a kiss, free of charge 😘
Thanks so much this helped me a lot! But in the first exercise after completing the products, did you forget to balance the equations?
thank you so so so so much! literally the only video that was able to answer my questions and was in depth enough! thank you, i owe you
He just explained in a few minutes what my teacher couldn't in an hour and a half.
Mr.seagle, this video is my savior
Never thought one video could get me so far! Awesome
Thank you very much! You explained it so much better than my Chemistry teacher!
HI, this helped a lot and this really helped. I am a 7th grader taking a test on this exact stuff on thursday. Thank you so much for your great videos.
Wow, thank you. Learned so much more in 12 minutes than in the week my teacher tried to teach.
Thank you so much! I was really struggling with this in Chem class and now I finally understand :) !
for 11:07 after writing snso4+ Fecl3 how come u didnt write sn2 becasue sulfatre has a charge of 2 and not write (so4)2 do u not criss cross the charges? or jsut blance them please help me
Sn (tin) originally has a charge of +2 while SO4 (sulfate) has a charge of -2 so they balance eachother out
Thank you very much for reiterating what my teacher taught today! Makes much more sense to me now :)
how do you know the charges of the transition metals
Thanku very much sir..... I've searched so many videos but clearly I understood in ur video.... Thx😊😊😊😊
learned more than 5 hrs of my teacher teaching in 11min ty
This helped so much right before my exams as practice.
why is Na being switch with Cu instead with SO4? i think NaSO4 is the right combination. please correct and give me reasonsif i'm mistaken..
2 questions for the first example: why is Fe always assumed to be Iron (III); where did the third chlorine atom come from?
My chem teacher is Indian and he doesn't know how to speak English very well and it's thru online 😭 I'm so frustrated so here i am trying to watch every RUclips video that exists
how do you know copper on the second to last is +2 or just +1??? because first you said +1 and then when you wrote it you said +2.
:/ i understand how to figure it out when theres a compound and it gives it away, but I'm confused with this one.
In the first example you have two chlorine on the left and three on the right, how is that correct?
Thank you
how do we know that in number four, copper has a charge of 2+?
How is the ending not 3SnCl4 + 2Fe2(SO4)3 > 3Sn(SO4)2 + 4FeCl3
I don't get how it is balanced at the end.
This is what I got too and I don't understand deny it wouldn't be this.
Please clear my doubt, how to detect colour change in reactions ...?
This helped me a lot. Thank you very much!
the charges don't balance on each side on the last example on 6:13?
the iron chloride (iii) with calcium sulfate example is wrong. it should have been 4FeCl3+3Ca2(So4)2 ---->2 Fe2(So4)3 + 6CaCl2 because the sulfate (polyatomic ion) has a -2 charge and Ca ion has a +2 charge . I have balanced it as well in case you want to know
@@simarthe-mushypoola9356 its CaSO4
Not Ca2SO4
These 11 min. Important for me thank u
Thank you so much :) - One question though, why is copper (Cu) +2 charge at 5:44? Thats the only part Im not so sure about.
Ok so copper and nitrate were together. We had to find out the carge of cu, but we already new the charge of nitrate which was -1. There were two nitrates so the charge would be -2. And to make both parts equal then cu had to b positive 2. That way it would b positive 2, which was copper, and negative 2, which was the two nitrates together. Hoped that helped
Ohhhhhhh, ok thanks so much m8 :)
sorry i don't understand. it does not show where there are 2 nitrate
At 4:54 why is it that N in Li3N does not have a 2 subscript. When does the diatomic elements play in?
Diatomics only come when they are by themselves. In a compound, number of atoms is determined by the charge on the other atoms.
Iron can either be Fe2+ or Fe3+, however, when predicting chemical equations, it is suggested that you use the lowest charge, which would be Fe2+. Not quite sure why he used Fe3+, and I assume it would be up to your specific teacher whether this in incorrect or not.
***** Because the problem is dealing with Iron (III) Chloride ....
@@serggla924 Why though. Is Fe (II) not viable at all for this reaction, or is that just the nature of this problem?
when he say like fe is usually +3. how do you know that. like not that it normal is that but that where did that +3 come from?
It is shown in the brackets as Iron (III) as a way of showing the charge just like how Tin ,Pb, has a (II) after it to show it has a +2 charge because bothe Iron and Tin have different charges
can synthetic and composition be used interchangeably?
Sooooo much help, i thought i was going to fail AP chem. now i just need to catch up on gas laws and molarity and im good
Love your videos they help a lot but maybe slow down a little when balancing?
2:19 - A little mistake, because Fe has to be 2+
But if you choose 3+, then you have to equal amount of Cl, Fe and Cu on each side. This means that you have to have this:
2 Fe3+ + 3 CuCl2 ------> 2 FeCl3 + 3 Cu2+
Have a good day :-)
Yeah this threw me off a bit. Thanks
WHEN DO YOU USE +2 and +3 for Fe??
omgg thts what i need to know!!!!!!!!! and my exam is tomorrow - and i dont know when to use which
ahhh
thank you! this help me so much on preparing for exam
Extremely well made video, thank you!
How do you determine what reaction there is based on the reactants only? I can only determine it when I have the entire equation.
You can a best guess. For this level of chemistry, I stick to 5 types: Composition, Decomposition, Single Replacement, Double Replacement and Combustion. We don't try to predict products for the exceptions or for anything that is not one of these 5.
Thank you so so much! This helped tremendously!
Thank you this makes a lot sense now
OMYGAWSH! This video helped me sooo much! Thanks for posting it :P
My exams are near and this is so much helpful 😀😀😀😀😀🙃🙃🙃thank u🤩
good lesson....do you use a clicker software??? you write fast with the mouse

excellent video my man!
Thank you so much for the video, it was really helpful and I've learned a lot....
Thanks a lot. You gave me a clear idea.😊😃😄

Why charge on iron not +2 in the first example
How do the charges come down?
why is Li+N2=Li3N and not =Li3N2 (I would like to know without balancing first)
Thank you for the video it really helped me out !
At 6:03 where did you get H2 ? Hydrogen has 1+ cation
hofbrncl
You are awesome dude u cleared all my doubts
WORKED AMAZING FOR ME THANKS A LOT!
Good job sir
THANK YOU SO MUCH DUDE
Thanks a lot
..... It was a trouble for me. 😊
Why does Fe and Cu change places?
at 4:50 did he forget there was two nitrogens on the reactant side I'm confused, help
Nitrogen is a diatomic element which is why he wrote it out like that. it still is treated as a normal nitrogen atom it just written as N2
Someone please answer! Why do you get Fe3OH in the second problem where he pauses the video? Mg(NO3)2+Fe3OH. I thought Fe was a transition metal and had no charge, so for my answer I got Mg(NO)3+FeOH???
Because over here the valency of iron is 3 and that of hydroxide is 1- so they switch and hence becomes Fe1-OH3 which will be written as Fe(OH)3, OH is in the bracket because only hydroxide is meant to be 3 and not iron because it is one and so we write OH in the bracket.
Question: What happened to the 2 at the end of N in 6:11 ? Can someone explain this to me? thx
Ohio
love trying to do chem in july... anyways thanks for the vid. Helpfull
Great video, thank you
Slow the fuck down and right the charges for all of them atleast
*write
Your an absolute master. plz can you send me a link where i can get all the charges and ions of all the elements.
for 2:48, I get that we need to add a 3 in the Cl.. But it's not balanced. Cl on the left is only 2.
why is there parenthesis around OH at 3:10 ?
In order for the charges of Cu and OH to balance you need 2 of the OH. That would give you a +2 (from Copper) and -2 (from the 2 OH).
+Marc Seigel please answer my question i have a test tomorow
Why is Fe 3+ charge and not Fe 2+ so confused on this?
There are 2 oxidation states for Fe. One is +3 and the other is +2. It will all depend on how the Iron is stated. If it's Ferric, it's Fe+3. If it's Ferrous, it's Fe+2. Typically, most of the p, d and f orbitals have 2 or more oxidation states. Fe is one of them.
How do you know FE is +3? 1:57
Very nice Thank you very much.
and wouldnt iron have a +2 charge?
no balancing required
Thank you.
its useful for me I dont understand it but now I understanded it.
Thanks this vdo is very helpful but I didn't understand hydrocarbons
Thanks a lot, plzzz show me how to get the product
God bless you
awesome,thanks
Very helpful
u have predicted the products but they are not balanced
+karnelu rapaka in this portion of the video, I was only focused on predicting the products. In class, I have my students predict and balance.
then why did you add balancing to the title? Still helpful though
I didn't understand how the charges are positive and some are negative
But we don't have to consider the charge only the number
you probably had your test already but if you didnt, you can see which elements have a negative charge and which have a positive charge on your periodic table. you can just do a simple search up on google like like "trend for ionic charge on periodic table" each period has a different charge
Thank You
Thankyouuhhhhhh sooo muchhh❤❤❤
thank u so much..i subscribed
Where is the 2 on the N
i dont get how it is cl3
Because in that case (not specified) Iron (Fe) had a charge of +3, and in order to balance iit in its new FeCl Molecule, there has to be 3 Cl atoms.
What level is this? (Grade)
Settle Down Prostitutes well when you get into high school there are 3 other SR formulas 2 other synthesis formulas 1 more DR formula and 5 other decomposition formulas (10th)
Good video
Thank u soooo much
example no.1 is not balance its 2Fe + 3CuCl2 >>>>>> 2FeCl3 + 3Cu
i still don't get this and i have a test on it tomorrow :)))
