In your graph of Temperatures, is the Y axis percentage Yield? Thank you so much. Last year I had a hip replacement and I am now in GCSE year, and your videos have really helped me. Oliver
Well it's the percentage of ammonia in the mix when it reaches equilibrium. This is a bit different to percentage yield. The percentage yield is (number of moles of product / maximum possible number of moles of product) x 100. With the Haber process, the ammonia manufacturers do a number of things to increase the amount of ammonia eg recirculating back over the catalyst. These have the effect of increasing the percentage yield.
Hi sir, I really need you to do As level chemistry please i need your help. The only reason i passed last year was because of you and i got all A. Please help
Hi sir if you remember me from the mock comment on another video well tomorrow is my final igcse paper4 exam and I would like to thank you very much for all of the help and support over the last two years
I was wondering when you will finish the physics paper 2 and biology paper 2 videos. I have been using your videos for AQA Trilogy science revision and I find them very useful. I have made notes on everything except the ones above. I have my mocks in mid Feb and I was really hoping if you could finish them before it as I really want to do well in them. Thanks and I will be waiting for your reply.
Hi sir, I’m just wondering if you will be doing a level physics, biology and chemistry videos once you have finished doing the GCSE videos for the new spec? :)
La chateliers principle states that if the concentration of reactants is increased then the forward reaction is favoured to use up more reactants. If the products are increased the backward reaction is favoured to use up products
Ideally the reaction would be carried out at a high temperature to increase the rate of the reaction. However, if we did that then the yield would be very low (as the forward reaction is exothermic). So we choose a "compromise" temperature which is not so hot that the yield is low but is not so cold that the rate is low.

I don't based my videos on the CGP books. I base them on the AQA specification. If you learn my videos, you will have covered the topics that you need. But bear in mind that the exam will require you to APPLY the knowledge as well as simply recall it.
hi sir, in the mock exam, I had a question on the definition of internal energy of water. I wrote that it is the energy that the particles of water get. so , would I get the mark for that? it would be really useful for me.
It depends on what your teacher's markscheme is accepting. Personally, I think you would need to be more specific to get the mark. It's the kinetic and potential energy of the particles in water molecules.
Hey, im currently in year 10 and the only science subject im struggling wit his physics due to one thing. I just don't understand how to re-arrange formulae. For example say if it gives you the specific heat capacity, then calculate the latent heat by re arranging the formula, i just struggle. Please could you make a video about this or explain in the comments? Thanks!
Hi. I'll try to make a video on that before the exams. However, please be reassured that you are generally not required to rearrange equations that many times in the exams. Usually, they're fairly straightforward.
The yield is the amount of a substance (in moles) that you get compared to the maximum amount that you could have got if the reaction had fully completed. It is usually stated as a percentage.
whenever I hear:
"remember you'll find plenty of questions..."
it puts a warm feeling in my heart
SAMEEE
yes brooo
I get stressed bcoz of exam

Are you grade 9 english langauge
This man is out here saving my life because of quarantine
Me too 😂😂
@@diaryofablackgirlfromkampa5332 same lol
i'm a simple gcse student, i see freesciencelessons.......... *i click*
Same
So me!
@@Saffins so you
RIP year 11s
My Chem 2 paper is this morning and this guy is single handedly saving my grades
LEGEND THANK U. WE LOVE A SCIENCE KING.
my paper 4 chemistry is in less than 3 hours, just wanted to thank you for all that youve taught me in physics and chemistry.
paper 4?>>
??
?
how did u do. I've got my paper 2 tomorrow morning
You are honestly the best person in the world. I hate chemistry and you are a literal savior. THANK YOU SO MUCH SEAN!!!!
This is for sure one of the harder concepts to understand but he makes it so easy
I just made more notes on this whole topic in 20 minuets. thanks! feeling alot better about chemistry this time compared to last mock.

The only reason i passed last year was because of you and i got all A.
Please help

how did they go?
@@sajamily2404 they never answer
our school made this sm more complicated than it needs to be smh
saamee ;-;
for equilibrium reaction the reactants need to be in the state of gas?
No they can also be in solution.
@@Freesciencelessons safe
We need you for A Levels!
Hi sir,
I have got a question. Can you do a video explaining "The water cycle", please? Thanks.
Very good explanations. Like 👍👍From India 🇮🇳🇮🇳 i
ABSOLUTE BABE
steady on charlotte
Yeah charlotte
Hi can you please make a video on increasing, decreasing functions
Got my exam in like 2 hours 😣
Samiirah Farah how did they go ?
Same.
do we need to learn the equation of The Haber Process?
Definitely. You could be asked it in your exam.
absolutely pooing myself for tomorrow, chems been a free period for 3 years now i pay the price

He's gonna finish it before the 2018 exams. So probably not before February
How did you do?
Tommorow now
man i loove youuuuu
Hi sir, I’m just wondering if you will be doing a level physics, biology and chemistry videos once you have finished doing the GCSE videos for the new spec? :)
Yes I will be doing Biology and Chemistry A level videos but not Physics as I have never taught A level Physics.
Freesciencelessons okay, thank you :)
1:59 Can someone please direct me where it is?
Can you please explain the equilibrium shift if there is increase and decrease in concentration?
La chateliers principle states that if the concentration of reactants is increased then the forward reaction is favoured to use up more reactants. If the products are increased the backward reaction is favoured to use up products
how come videos like this and le chatiliers principle aren't included in playlists
They're triple only, not to confuse
I love the fact that this vid is exactly 4:20 mins. Lol
Could you please simplify the term “compromise temperature”
Ideally the reaction would be carried out at a high temperature to increase the rate of the reaction. However, if we did that then the yield would be very low (as the forward reaction is exothermic). So we choose a "compromise" temperature which is not so hot that the yield is low but is not so cold that the rate is low.
Hi, are you planning to finish biology and physics paper 2 before the first set of 9-1 exams this year?
JDCFC yes
What I want to get in august
Chemistry-9
Biology-9
Physics-9
Maths-9
Pe -9
Geography-8
German-7
English lit-7
English language -7
Remind me to come back in august!!!
YO bro come back
what did u get?
What about increasing the concentration of reactants?
it will shift to the right to produce more products as there are fewer molecules on the right side.
@@LouisHillJ isnt the fewer molecules rule for pressure? so if you increase the conc of reactants more products are formed.
What is your favourite Science
Hi sir,
I need your help in my chemistry please I am very poor on chemistry
Thank you
It's me again 😀, do you know you science vids, will this cover all the topics I need to know for my final gcse exams this year?
OriginalLegendz yes
Do you do Aqa 9-1?
Yes all my videos are specifically written for that.
Freesciencelessons yes thx :D
Link to your revision workbook? It didn’t show in the video? ;-;
anyone is all his aqa 9-1 videos suitable for triple science with the new spec plz respond if u do know
Yes if you're doing AQA triple then you need all the 9-1 videos.
thank u sooo much if i learn all these videos will it get me a high grade and do these aqa videos come from the science cgp topics
I don't based my videos on the CGP books. I base them on the AQA specification. If you learn my videos, you will have covered the topics that you need. But bear in mind that the exam will require you to APPLY the knowledge as well as simply recall it.
oh okay this is the new aqa spec for this year??
What does triple chemistry mean?
People that have taken Triple Science
basically its for more advanced students in terms of brain capacity and mental capabilities
Does pressure also affect rate? As more particles in a smaller space mean more collisions?
Yes that's correct. High pressure = faster rate.
will taking notes learning and knowing it all get me a high grade in triple science for the new gcse triple science new spec 9-1
Sir, at 2:35 isn't it the trade-off between the rate of PRODUCTION and the position of the equillibrium?
No it's the rate of reaction. Remember that at equilibrium, the forward and reverse reactions are at the same rates.
Understand! Thank you for this.
hi sir, in the mock exam, I had a question on the definition of internal energy of water. I wrote that it is the energy that the particles of water get. so , would I get the mark for that? it would be really useful for me.
I meant the energy that the water particles have. sorry.
It depends on what your teacher's markscheme is accepting. Personally, I think you would need to be more specific to get the mark. It's the kinetic and potential energy of the particles in water molecules.
Thanks , plus I wanted to say that your videos are amazingly amazing, I know it may sound wrong but I don't know any other way to describe them.
I 've got one last question, because I didn't quite understand what a milliampere was. is it like a 1/1000th of an amp or something else?
Thanks for the comment. Yes a milliampere is a thousandth of an ampere (milli means 1/1000).
Sir what’s an equilibrium
When a forward reaction is taking place at the same rate as the backwards reaction (Scientists call this the Dynamic Equilibrium)
does this help for edexcel aswell?
PLEASE MAKE VIDEOS FOR A LEVELS
he does
where is your revision workbook
Thank you!!!!
late night revision for tomorrow... *sighs*
Revising 1 hour before exam 😂
god bless everyone today
amen brother🙏
Tomorrow's my exam wish me luck
Night before gang
