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!
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!)
If you’d like to practise what's covered in this video, check out the lesson on our platform: cognitoedu.org/coursesubtopic/c2-gcse-aqa-h-t_10.03 - it's totally free, and has been built to make learning and revision as easy as possible. The main features are: - Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown. - Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on. - Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like. - A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts. - A comprehensive bank of past exam papers, organised both by year, and also by topic.

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
Should I just paint the scratched area on my painted metal beam or something must be done before that? What will happen if you paint an already corroded area? What will happen if some moisture trap under the paint cover?
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!
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?
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
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?
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
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
@@Cognitoedu in cognito's name, we believe
you the the king of science. I love your explanation soooooooooooooooo much.
Thank yoooou Engi 🙌
these videos are really 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 !!
The explanation in every one of your videos is so helpful. Thanks
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.
very comprehensive and interesting!
Thanks, this is helping for my exam
Wow super explanation bro....
this is the best chanel for chemistry ever you help me with my finsl exam thank you
This is so enchanting 😌😥
is this it has our endless sumer finally come to an end🗣🔥🔥🔥🔥🔥🔥🔥🔥🔥
this is so good omg!!!!!! Thank you so much for the help!!!!!!!!!!!!!!!!!
Yay thanks Rayd, glad you enjoyed it 😊
Thank you brother 🙌

Thank you brother. I really enjoyed this video of yours from Papua New Guinea🇵🇬
can you please tell me which app or software you use for creating these animation videos?
Istg
Me as a teacher making sure I teach the right concept...
Your my teacher 😭
@@unnamedsmith3276lmaoooo
Thank you, very detailed and helpful!
This topic was an absolute killer for me but I understand it soooooo much better after this amazing video
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
Very instructive, thanks!
I can understand your topic I am from Pakistan 😊 Thanks a lot bro👍🏻💯
This is really helpful, thanks
YOU ARE THE BEST I HATE CHEMISTRY BUT YOU HEAL ME😌😌
😂
How does sea water affect rusting?
great video
Should I just paint the scratched area on my painted metal beam or something must be done before that?
What will happen if you paint an already corroded area?
What will happen if some moisture trap under the paint cover?
i helped me for my presentation for chemistry> thnx
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
i love u n ur vids❤️
5:28 so that why its called "galvanized square metal"
good one good one very good one
Thanks
2:02 if no oxygen then how water can exist?
Chemistry exists:
Maths: Am I a joke to you?
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?
How you make a animation of corrosion?
So helpful
Nice
My class teacher used 90 minutes to teach us what you teach in 6 minutes
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
He is right
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
Oxygen is chemicaly bonded to hydrogen and can noy simply react
Thanks!
Can you please please download an A-level series 😍😍
Thank you so much
You here for next chemistry exam
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?

What is coating
Erg helpful
Why is zinc more reactive with oxygen? Asking for my project hehehe
24 CAROT DOESN'T RUST, THEY WORK WITH 18 CAROT
I have exams today in Cognito I trust
❤1
hi people from my class 😩
Was gud I’m back man remmember me Mack
Exam in a month 😭😭
