I am 46 years old and refreshing my GCSE chemistry knowledge before taking on a new job, thank you so much for this, I now understand this in a much clearer way than when I sat my exams
Rowan Hebblethwaite nah they’re the same, each of them have their own strengths and limitations in each different topics. Thanks to both of them, i learn more from them than in school
i thought this topic is gigantic and i will never get this topic and i wont know anything, that has changed because of you, thank you very very much, much love 😁
Thank you! I need to be able to identify them with only a periodic table and so far most videos have a pre-made list. Thank you so much for explaining!!!
I've learned about single and double displacement reactions but I was thinking if triple displacement is possible? If yes! then how is it decided which element displaces the other??? when there are two metals the element can displace???? I was trying to find out about the same and I came across an equation: 2 AgNO3 + 2 NaCl + K2CrO4 → Ag2CrO4 + 2 NaNO3 + 2 KCl what type of reaction is this??? But why did Silver, in the above equation displaced Potassium and not Sodium?? How is it decided who displaces whom??? Please help!!!
Why does the order of decreasing reactivity differ from the decreasing metallic properties so often ? Ionization only differs a few times but reactivity isn't the same. Normally I had expected that the reactivity series would match (reverse) with the order of ionization energy (as the tendency of releasing electrons depends on ionization energy)
Hey Thanks again sir. The video really helped me and you really gave me the idea of displacement reactions. But can you please give a deeper understanding about them. But again thanks for the video. You should have like 1billion subs.
in the exam they ask me about what observations i made during displacement reactions, i have a new exam coming up so do you have a video on that, like on reactions that would tell us like the colour change and everything observable?
Cognito, I know this will seem strange, but is it alright if I have used your picture of the reactivity series of metals in my video( 0:08 ). I have credited it to you in my description.

you're so a hardworking person.
@@jamiewallace3546 no one asked you comment either
@@jamiewallace3546 oh, I was scared. Really scared
@@jamiewallace3546 Watch your language big man. Think you're so tuff. No one asked to see how big u r.
@@jamiewallace3546 LMFAO.... Big Jamie Wallace.

hope this helps
Thanks, i used to have something way worse pre schools can make awesome classes and the rest I just learned
lol tyyy
You forgot lithium
Okay a STAY helping me learn chemistry 😭😭💜💜
Babes where Lithium tho?
you are my lifesaver, don’t think i’ve ever watched so many videos from one channel in a span of weeks!!
rightt
your so underrated
Chaima Moali hes better than free science lessons
Rowan Hebblethwaite nah they’re the same, each of them have their own strengths and limitations in each different topics. Thanks to both of them, i learn more from them than in school
@@jonathanaliesaputra5075 you're right

@Momoo and you’re so illiterate
i thought this topic is gigantic and i will never get this topic and i wont know anything, that has changed because of you, thank you very very much, much love 😁
Ah that's awesome to hear Nahu, glad everything is making more sense now 👍
What a clear explanation, very precise! Thank you!!
I'm really enjoying this simple explanation, using it to help my friends children with GCSE chemistry! Thank you.
Thank you so much for this video You absolutely SAVED my life
Your videos are so simple to understand unlike how it is taught in my school..thx again
非常感謝先生，你如何解釋中國巴基斯坦人的接受性系列愛真是太神奇了 😊😊
Thanks Ignito without you I would have failed my chemistry exam
You make complicated things simple and easy to absorb by ordinary child brains. Thanks!
Thank you so much......really appreciate your effort😘🥰
thank you man, you made it so simple
same here lol
lol same
I love how chaotic the thumbnail is
Thankkkk you so much in the whole term this video made me understand it instantly.
You helped us all, the only things I wish for on my birthday are a gaming mouse and more videos from you. Keep up the good work!
Aw thanks Mustafa, hope you get them both 😉🥳
Did you get the gaming mouse ?
One year later and we still don't know if he got the gaming mouse.
u got ur gaming mouse???

I WISH THIS MAN WAS MY TEACHER!!! HE IS AWESOME! MY CHEMISTRY TEACHER IS WORTHLESS COMPARED TO HIM!
Brilliant video mate, Now i can do my homework! :D
Wow! it feels like only yesterday your channel was at 247k, keep up the good work!
I literally love you right now
thank you so much for the video it helped me in my end of year exams
Iam the 1k like. Proud to be a Cognito member.
Thank you! I need to be able to identify them with only a periodic table and so far most videos have a pre-made list. Thank you so much for explaining!!!
literally thanks
Very lucid explanation. Good job.

Please help!!!
May god bless you .... way better than my tchr 😢❤
my chemistry exam is the day after tmrw, thank you so much
@Cognito, you are the best! You have helped me learn about nearly everything I need to know for common entrance exams! Thank you! Keep doing this! 😀
Glad to hear we could help!
Thank you soo much for making these videos the way you do
it really helps give a vivid image of what your trying to explain to us
If everyone watched your TH-cam videos they would pass all subjects in under a year
your channel is amazing.
You so much you are making my life easier from these videos❤
Thank you So much, this video was very helpful and I learnt a lot.
Thanks Helindu, glad we could help 😊

It really helped
Thank youuu
Thank you so much this video helped a lot!!
The lucidity of explanation 🖤🖤🖤🖤
is this okay for someone in year 7?
we didn't take it in grade seven
You wont need to remember anything about the ions but knowing some basic knowledgd about outer shells would help for when you learnt about it in yr 8
And you wont need to know about the water+acid-> hydroxide
2:37.....should have been same no. Of moles rather than mass👍🏼👍🏼
Thank u so much for this vid I now understand much better ❤
in the exam they ask me about what observations i made during displacement reactions, i have a new exam coming up so do you have a video on that, like on reactions that would tell us like the colour change and everything observable?
Great video
Calcium needs to be 2+ when an ion on the first slide.
Cognito, I know this will seem strange, but is it alright if I have used your picture of the reactivity series of metals in my video( 0:08 ). I have credited it to you in my description.
Yep that's okay
This vid is SOOOO good thank you
You just saved my test
How to remember the reactivity series:
'Phillip Schofield loves calling me a zebra I can't stand the guy'
Potassium
Sodium
Lithium
Calcium
Magnesium
(all end in ium)
Zinc
(below are the three jewelry metals)
Copper
Silver
Gold
Awesome lecture sir
You’ve earned a new subscriber my friend
Awesome, thank you!
But I thought that magnesium is more reactive than calcium, me and my teacher did this in school
Silver and Gold are not covered in the reactivity series is this video but it is still a good video
this is a selective list right?
Thank you 😊
Broo you r the best
Thank you so much for the support :))
Wow good job how do you do these videos I think that you are not a human 😳😳😳
Thank you
THANKKK UUUU I LUVVVV UUUU
