Redox Reactions: Crash Course Chemistry #10
[youtube http://www.youtube.com/watch?v=lQ6FBA1HM3s&fs=1&rel=0]
All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemist…

CLEAR & SIMPLE – This video tutorial show how to solve Chemical Reactions…which is also called Predicting the Products.
Video Rating: 4 / 5
Redox reactions were always most complicated part of non-organic chemistry
to me… or of any chemistry… except biochemistry, which totally blows my
mind (even though I am a biologist)
Not funny, not helpful and too fast.
Well reduction really is gaining more mass AND gaining more charge so the
opposite of Reduce.. BUT I think of it as reducing the charge number
(making it more negative).
Ok I give up. Chemistry is just too complicated. I’m coming back to math.
At 9:11 “On the reactant side” should have said “On the product side”
because Ag + R-COOH are products, not reactants.
This series would have benefited from a whiteboard. Also, that is a
needlessly complicated way of balancing redoxreactions. But hey, it works
Anyone else finds it impossible to learn math from videos? I need to
actually practice math, pen and paper style, in order to learn. =/
When you balance the number of Electrons in the N2 –> 2NH3 reaction.
Shouldn’t there be 6e on the left side? Because 2*-3 = 6e
what
God I love chemistry <3
So my redox test is tomorrow and I was feeling so lost and confused but
this video totally saved me, I MIGHT ACTUALLY PASS IT
are reduced atoms negative and oxidized atoms positive? I really don’t
think so for sure, but it would make this easier to remember…
First one I’ve watched that I felt like I really didn’t follow what
happened and I’m not so sure I would even with watching it a second time.
But I”m sure this would be an awesome refresher for someone who had already
learned this before.
I love this course, but I don’t really get all the camera shifts during the
calculations. It makes the math so much more confusing than it has to be.
The animations during the backgroundstory are awesome tough, those really
keep me interested.
for someone who’s new with redox-reactions,its gonna be difficult to follow
cause he’s going TO FAST en he talks a lot whats irrelevant with the
subject. And showing the reactions weren’t so good he made it like puzzle.
now for someone who’s new with the redoxreactions ,and you make it like a
puzzle,well lemme tell you this HE WONT BE ABLE TO FOLLOW. the video is
good but you should make it more easier to follow :)
You forgot to mention Disproportionation Reaction where both Reduction and
Oxidation take place on a reactant.
i real need a help in this, am going to write exam in 3 days to come but,
this topic is kind of challenge
Paseo!!!
I find this very useful for revision.
Its fast and efficient especially for those who left revision to the last
minute *cough, cough*
I’m not sure about new learners. Do you guys get this stuff?
WHOEVER INVENTED THIS CHANNEL (I, THE MOST DESPERATE STUDENT TAKING PART IN
THE A LEVEL WHO NEEDS A HIGHER RESULT) thanks you.
PS if anyone knows a good website which can help me in my a level physics,
bio, chemistry AS. feel free to tell me the website. JUST PWEEESE TELL ME
IM SO SAD AND DESPERATE
Having been completely confused in class about this and doing some
desperate research at home (no one in my class could help because none of
them understood it either) this video (having to break it down, of course)
actually made me grin when I managed my first complicated equation! Thank
you so much!!!!
I thought Hydrogen had a -1 charge with metal and boron?
Can someone tell me an easy definition of Titration?
Too fast… Slow down please…….
You forgot to mention Disproportionation Reaction where both Reduction and
Oxidation take place on a reactant.
would it matter what order you put the new product? ex. Li+CaO –> LiO+Ca
or Ca+LiO
This is vague as hell. how are you suppose to know which qualify for double
replacement or dont move at all, or turn into water!
Man! This was loud and clear, this was better than the lessons from my chem
class. I took the quiz and I got 105%!!!! Thanks Man!!!
Just curious, why didn’t you balance the equations? Was it just to save
time?
This saved my chemistry grade !! Thank you you’re the best !!!
Thank you for this awesome explanation! I was gone for a couple days from
school and this makes so much sense.
THANK YOU!
This really helped my allot. Thank you so much :)
Thanks a lot :D
hey, 5:10 you have MgCl2 + Li2O. I understand that metals have differing
reactivity but I don’t understand why magnesium is more attracted to oxygen
than the chlorine that it’s already bonded with. Do non metals have an
activities list or a preference to certain metals that I can study? I hope
I’ve communicated my question as this has been a major hiccup for me that
needs to be resolved asap. Thanks
HEYY I NEED YOUR HELP I SUCK AT CHEMMM CAN I SKYPE U
Most combustion reactions don’t go to CO2 and H2O, only with hydrocarbons
does this happen.
Thanks a lot! I’m now ready for my chemistry final exam
THANK YOU
can someone please please answer as soon as you see this – in the double
replacement problem why isn’t it Li2Cl ?? and why doesn’t aluminum in the
first 3 problems have charge of 3
How do you predict the products when given structures of organic
molecules?
Is there an easy way to figure out the number of water molecules in acid +
base > salt + water reactions? I always seem to get the water molecule, and
have left over H and O’s and I never know what to do with them. Any help is
appreciated!!!!
How do you find the charges?
MR. Post.. ur a nail
Thanks. This helped a lot.
Thank you so much! I missed an entire week of school and we have a test
tomorrow and this was so helpful! You basically saved my grade and GPA!
This was really helpful, I have one question though. Where did the 3+ and
1- charges come from? Thanks!
thanks! I have a chem test tomorrow
This is the best. Totally passing AP chem exam. Thanks <3
Thankyou!!! This cleared up so many of my questions!
