AAAAA you made this video such a breeze! i cant believe it, i knew NOTHHING before i watched this video and this video made the paper extremely smooth for me so thanks!!
This video really helped me and will in my mocks coming up thank u. It takes ages to go through alot of the chemistry topics and going through them quick and easy to understand is great 👍
Hi!!!! For the AQA TRIPLE CHEMISTRY spec, it states we need to know the reactions between group 1 with chlorine, oxygen and water. Previous exam Qs have asked what you observed when adding grp 1 metal with water. Could they ask what is observed when adding grp 1 metal with oxygen? chlorine? if so, what would be the observations be? ~~~~ Additionally, in unit 4 of the same spec (chemical changes), the spec states that we need to "recall and describe the reactions, if any, of potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper with water or dilute acids." Do we need to know observations for ALL these metals when added with water and dilute acids (like what you observe when add the 2) If not, what exactly is this bullet point asking??? What will we be tested on from this bullet point? Thanks Thanks soooo much! :)
They can, and they have. Oxygen makes alkali metals tarnish. Reaction with chlorine you start off with green gas, which disappears, and you see a bright light and then white crystals form (because you make salt). Yes, you need to know for all of them but basically you just see bubbles (if anything) and the number of bubbles is determined by how reactive it is. With water even Magnesium is incredible slow. With acid, you'll see Iron and zinc producing small bubbles but not copper
No, because that's not how standard form works. In standard form, the first number has to be between 1 and 10. So yes, 12.04 x 10^24 would be equivalent, but it also wouldn't be a correct mathematical representation.
@@ayesha3429 I’d been extremely stressed at the time in which I was revising which lead me to using this as a last resort.However I have /did revise before using flash cards so I had prior knowledge and now I have made flash cards with the spec. Essentially what I’m trying to say is that I think I got quite lucky as this is a summary video which briefly goes through everything but not thoroughly (as the person in the video states). Sorry for the long paragraph 🚶♀️
Not an acronym but a mnemonic. Purple soda lemonade cans may also contain zebra idols that lead highlands cows somewhere greatly peaceful. (It's got some extra ones in there, but it's what my year 9s in 2017 came up with and I've stuck with it ever since 😅)
Thank you for this video very helpful!!!! But whenever i watch your videos i find it extremely difficult to hear what youre saying and my speaker is on 100 with no noise in my surroundings but its still difficult to hear you.
make sure you write notes while going through this, and watch Science shorts video of covering the entire science in 30 mins right before the exam. then you wont fail.
The different exam boards have different specifications, so the exams cover different things. Everything in here is correct Chemistry, but the Edexcel papers will also contain some content not covered in this video, and there are differences too in terms of e.g. what is Higher Tier only.
Yes. Well, rather, you can use it for Higher or Foundation, but if you're doing Foundation look out for when the headers change colour and say Higher Tier only
This account is easily the best one I’ve found yet, I’d watch this over primrose kitten or free science any day!
ikr
Free Science is soooo boring 😭😭
smokeeee
free science goes over things way to quickly
@@bluesky1042 i agree, i physically cannot listen to one of her videos without focusing on how annoying her voice is rather than the content 😭😭
Your video for paper 1 bio was a saviour, so of course I'm gonna have to watch this one as well. Good luck for those sitting exams on Monday!
Can use this video if I'm taking combined higher (trilogy)?
@@bigword3600yep
@@bigword3600 no shit
How did it go😊
Deserves more attention than other channels... really concise
watching this the night before of my exam bcs haven't revised for chemistry😍
twins i honestly despise chemistry paper 1
same
did u pass?
paper one on monday! used ur bio video the night before and it saved me!! these r so helpful
good luck to everyone taking the chemistry test tomorrow
thanks mate gonna need it😂
This exam is going to be the death of me
@@sophieee765 how did you find it, i thought it couldve been way worse but that radox reactions with elements A B C and D got me i completely guessed them multiple choice ones. nvm tho
On UA-cam, I found the best chemistry revision video. It is engaging and informative, keeping my attention focused throughout. Thank you!
so helpful!
I recommend doing exam questions on each unit as you watch then a full exam paper at the end
omg that is so smart thank you sm!!
chemistry paper 1 is tomorrow- good luck to everyone !!!!
you too!! x
you carried me through biology like 5 hours before i had the exam, i pray on your success if the same happens for chemistry
Your biology paper 1 video honestly saved me on monday! Thank you so much for making these video and saving my gcses ❤
biology was a perfect paper, everything was balanced out they gave us a good paper this monday
@@bluesky1042 that aspirin question was not balanced, I had no idea willow bark even had a USE! My dumbass put night shade
Good luck to everyone taking chem tmrw! This video will save me haha
You can do it!
this video is the only reason i got a grade 8 in chemistry gcse, thank u so much
Howwww

doing that before every science
you are actually a lifesaver
😍 I'm glad you're finding my videos useful
found this so helpful thank you :)
I am here at 02 :00for learn this for tomorrow morning,good luck everyone
appreciate saving my gcses
Not me watchong this 7 hours before my test-
thanks this helped alot!!
keep up the good work
nice Kenma pfp I pray you do well bro
Thanks this went into lots of detail.
Thank you so much!
Used this vid for mocks got 9 now using for real gcses tomorrow
I'm glad it worked for you last time. Fingers crossed for tomorrow!!
@DrdeBruinsClassroom thank you. Also do we need to specifically know info abt fine and coarse particles. And what actually are they?
Good luck guys !!

18:45 there is a bit of an audio error.
A bit of repetition
43:02 Hi there, isn't it supposed to be 12.04 x 10^23 atoms?
No, because that's not how standard form works. In standard form, the first number has to be between 1 and 10. So yes, 12.04 x 10^24 would be equivalent, but it also wouldn't be a correct mathematical representation.
@@DrdeBruinsClassroom Oh, sorry my bad.
Anyone know where 510 comes from at 45:59 ?
If you go back to the start of the question, the question said there were 510 g of aluminium oxide.
@@DrdeBruinsClassroom thank you! Exam today and I’m not looking forward to it.
Hope it went okay!
@@DrdeBruinsClassroom certainly better than it would have without this thanks.

Also some stuff is summarised as if it weren’t it would take far too long ( which is understandable) the video would be extremely long .
@@ynawihs thank you so much. I’m just so worried for my upcoming mocks and I don’t know how to revise for science fully and quickly
@@ayesha3429hey no worries , try to revise key practicals Id spend some time in the summer trying to find a revision method that works for you
Last minute💪💪
Good luck fella👌
@@matthewclark2982 cheers😆😆 means a lot
is there an acronym to remember the reactivity
Not an acronym but a mnemonic. Purple soda lemonade cans may also contain zebra idols that lead highlands cows somewhere greatly peaceful. (It's got some extra ones in there, but it's what my year 9s in 2017 came up with and I've stuck with it ever since 😅)
i do foundation chemistry i hope i can get atleast a 4
Good luck!
What’s the difference between divalent molecules and diatomic?

Watching this 2 hiurs before my exam I’m so cooked
how did you do?
@@JaneSlaymaker aw hey I passed at got 4-4. You?
is this like every single topic included like if I just watch this video alone would I have covered all of the content in detail?
You would have covered every topic that is written in the spec, but not in detail because it's only an hour long!
this videos great but there are ads every 30 seconds
🤷♀️ UA-cam adds them, not me!
Thank you for this video very helpful!!!! But whenever i watch your videos i find it extremely difficult to hear what youre saying and my speaker is on 100 with no noise in my surroundings but its still difficult to hear you.
It's funny because some people complain it's too loud!
It's fine to me, maybe it's a problem on your end.
I completely agree! Im on a brand new laptop yet still her sound is very muffled?
Is this for higher
Yes. If you're taking foundation, you can skip any of the slides that say HIGHER TIER in the top right.
im going to fail but its fine i hate science, i'll come back august with my grade
make sure you write notes while going through this, and watch Science shorts video of covering the entire science in 30 mins right before the exam. then you wont fail.
@@midgetyt2886 thats what a good person does 🤦🏾♀🤦🏾♀ just say that you're selfish and move on

same I'm failing swell lmao
@@morduedocumentaries he's got a point tho.
just started watching this at 1am before my exams am i cooked?
same 🔥
Is this for higher tier?
Yes. If you look at the headers it changes colour whenever the content is higher tier only
Can I watch this even if I’m doing edexcel examboard?
The different exam boards have different specifications, so the exams cover different things. Everything in here is correct Chemistry, but the Edexcel papers will also contain some content not covered in this video, and there are differences too in terms of e.g. what is Higher Tier only.

i wanna pop the question tbh
real.
You didn’t go through covalent or metallic bonds
omg sorry there was a glitch with the video that ended it in 15 minutes sorry lol
I still havent revised im i cooked
its okay, gotta do that last minute cram before the exam
me too
I lterally cantt im so lazzyyy 😂😭😭
Maths tmrw 💀
same
Hi
i have an hour to learn all of chem kill me
Same 😭
