Filled up a page and a bit with this info, thanks for helping me revise! (The page was 29.3 centimetres long and 21.2 centimetres wide, so it’s a big page!)
Thank you very much, Cognito. I have struggled to understand the experiment of how rusting occurs but now I am fully capable of answering it on my exam!
Hi, I was wondering what you used to make this video to see if it would be helpful for my personal revision. I just feel it would help me a lot in all my subjects.
I cannot stress how much of a great channel this is, told my whole class about this channel, easy to keep up with and honestly saved my chemistry marks. Thank you. @cognito
I have a question that in the video you said that oxidised mean losing electrons and reduce means gaining electron but I think it is opposite. Please verify me
But then why am I still getting rust spots after painting with zinc paint? If the zinc is sacrificing then I shouldn't have rust spot on scratched paint?
Thank you so much! But one of my doubts still persists, does alloying come under the barrier or sacrificial methods of protecting iron? But, thanks again!
can someone explain why the iron won’t rust even though is exposed to air when zinc is in contact with it? since is exposed to air, won’t part of the iron that is not coated with zinc rust?
basically, the oxygen wants to react with the most reactive thing that it can. in this situation, it has two choices which is the iron and the zinc. since the zinc is more reactive, the oxygen ignores the iron and is attracted to the zinc. hopefully that cleared it up a bit
In the example with the nails in the test tubes, what keeps the nail from rusting in the first one with just water? Water is partially made up of oxygen, so what prevents the oxygen part of water (H2O) from creating rust?
You are a saint, there should be a “St. Cognito’s Day” every year, you make all of the info so concise and easy to understand thank you!
Ah thank you so much Ben, we're really glad you like the channel 😊
Lmaoo frr

you the the king of science. I love your explanation soooooooooooooooo much.
Thank yoooou Engi 🙌
these videos are really helpful - thanks

The explanation in every one of your videos is so helpful. Thanks

This is SO useful for taling care of our EXTREMELY expensive buhurt armor! Thank you!!!
I love the animation style! Thank you for helping us science newbies !!
this is the best chanel for chemistry ever you help me with my finsl exam thank you
can you please tell me which app or software you use for creating these animation videos?
Istg
Thanks, this is helping for my exam
very comprehensive and interesting!

Wow super explanation bro....
YOU ARE THE BEST I HATE CHEMISTRY BUT YOU HEAL ME😌😌
Thank you, very detailed and helpful!
This is so enchanting 😌😥
Thank you brother. I really enjoyed this video of yours from Papua New Guinea🇵🇬
Very instructive, thanks!
I have a question that in the video you said that oxidised mean losing electrons and reduce means gaining electron but I think it is opposite. Please verify me
I can understand your topic I am from Pakistan 😊 Thanks a lot bro👍🏻💯
Thank you brother 🙌
I really grap your tutor thank you very much for such great explanation
If you don't mind please work on kinematics physics portion I really need that
How does sea water affect rusting?
But then why am I still getting rust spots after painting with zinc paint? If the zinc is sacrificing then I shouldn't have rust spot on scratched paint?
this is so good omg!!!!!! Thank you so much for the help!!!!!!!!!!!!!!!!!
Yay thanks Rayd, glad you enjoyed it 😊
Thank you so much! But one of my doubts still persists, does alloying come under the barrier or sacrificial methods of protecting iron? But, thanks again!
idk
This topic was an absolute killer for me but I understand it soooooo much better after this amazing video
Me as a teacher making sure I teach the right concept...
Your my teacher 😭

This is really helpful, thanks
How you make a animation of corrosion?
Chemistry exists:
Maths: Am I a joke to you?
great video
i helped me for my presentation for chemistry> thnx
good one good one very good one

2:02 if no oxygen then how water can exist?
5:28 so that why its called "galvanized square metal"
In the example with the nails in the test tubes, what keeps the nail from rusting in the first one with just water? Water is partially made up of oxygen, so what prevents the oxygen part of water (H2O) from creating rust?
they boil it which apparently removes oxygen
The water is boiled for removing any oxygen particle from it
And the oil layer prevent from any addition of new oxygen particles
Nice
i love u n ur vids❤️
What is coating
My class teacher used 90 minutes to teach us what you teach in 6 minutes
Can you please please download an A-level series 😍😍
So helpful
Thanks!
Thank you so much
You here for next chemistry exam
Why is zinc more reactive with oxygen? Asking for my project hehehe
Erg helpful
I have exams today in Cognito I trust
24 CAROT DOESN'T RUST, THEY WORK WITH 18 CAROT

hi people from my class 😩
Was gud I’m back man remmember me Mack
Exam in a month 😭😭
