watch how we all spend hours revising this topic then AQA go and ask us a 1 mark question on it

you probably get this a lot but genuinely thank you so much for producing these videos i'd be lost without them

[@Freesciencelessons]

Thanks. I do get thanked by people but it's still nice to hear it. Good luck in all your exams and let me know if you have any questions on the videos.

[@softglow9]

Finally...it took me from 6am to 11:41am to finish this topic and making notes. Wow. Bless this channel - it's so simplified and no need for waffling.

E A good luck

watch me cram it in 5 minutes before the exam

I've been using this channel for 2 years now making flashcards and this is the final one!!! Thank you sir for these, I wouldn't be consistently getting 9s in the sciences if weren't for you :) they're so simple and so much less daunting to use than revision guides; thank you again!! (And good luck everyone with exams!)

i hate that this is one of the major focuses for the exam

[@destiny-powerhouse3260]

I believe this is the most difficult topic in the course. We have to memorise so many different equations for NPK. Do we need to know the symbol equations?

Do we?

[@TheKing-gw6ex]

Thanks this really helped (however laborious this particular topic may be) so I really appreciate it! I know it isn’t related to this video, but what’s the difference between a sulfate and sulfide?

[@Freesciencelessons]

Hi. Sulfate has the formula SO4 2- and sulfide has the formula S2-

Just finished my chem gcses moving onto ib chem now thanks shauno

[@diegobertora3470]

I think for edexcel we need way less detail. Only a few spec statements about fertilisers and we just need to know batch/continuous processes. I guess AQA just happens to focus more on this in particular

[@anthonynguyen1904]

Hey do we need to remember the symbol equations for the fertilisers?

[@anikamehra928]

shouldn't water be produced in the reaction with ammonia because isn't it a neutralisation reaction?

[@Freesciencelessons]

If the ammonia was dissolved in water (forming the alkali ammonium hydroxide) then yes that would happen. However, in this case, the ammonia is a gas not dissolved in water, so it is not an alkali therefore no water is released in this reaction.

[@davidoak7194]

Hi Sir, Considering the fact that i only have 3 months or less till the exam for the AQA GCSE Biology and i do Triple. I have covered B1, not B2, not B3 and B4 is covered and for the other sciences i have only done C1 not C2, starting C3, Not C4 and not C5. For physics i have only done P1 and Started P2. P3 and P4 not done. I was wondering because i covered most of the Paper 2 topics (B7, P7, P8,C8,C9,C10). I have finish C10 notes today. Your videos are really good as it did help me go from a 2 to 6-8. One thing that is worrying me is that i'm suppose to be going through exam question to secure questions for paper 1 topics making sure that i fully know that specific topic and how to tackle those types of questions that tend to appear in exams. Now i just confused what to do for paper 1 topics.

[@spogmai1148]

I'm on the same boat as you, I have the whole of paper 2 for physics left :(

[@broskibrobro1278]

Morning of chemistry paper 2 Hopefully this comes up

[@eeeeeeeeeeeeeeeeeeeeeeeeeee78]

tomorrow im gonna get asked a fat question on super triple mega giga epic phosphate

[@salamisupplier]

this is definietly the worst topic in chemistry

[@jameskonefal9491]

What do you mean the 'elements that have been taken up by plants'? Exam in a few hours chemistry paper 2 ...

[@kingpin7797]

could i ask a biology a level question please answer? Give a genetic explanation for each of these three situations 1. A couple has six children. The first 5 are healthy: the sixth has cystic fibrosis. Neither parent has the disease 2. Another couple has two children: both children have cystic fibrosis. Again, neither parent has the disease 3. A women with cystic fibrosis is told that it will be unlikely her children will have the disease, but they will all be 'carriers' and could themselves have children with the illness

[@siguchan7485]

is this really a level? surely these can just be explained with a punnett square

[@Freesciencelessons]

Genetics is about probability. These are not guarantees about offspring, they are simply probabilities. In cases 1 + 2, both parents must be carriers. On average, 1 in 4 offspring will have CF and 2 in 4 will be carriers. But these are only probabilities. In case 3, we do not know the genotype of her partner so we have no idea of the probabilities.

[@kingpin7797]

thank you soo much

[@rosahoneywood6778]

Yeah I learnt this for gcse biology 😅 use a punnet square and remember cystic fibrosis is recessive

[@botanicaltears]

Ayeeee it’s meeee CF. Anyway I think you meant they don’t have the disease but they ARE carriers lmao

[@YM-uu4lp]

are all the videos for the aqa syllabus?

[@Freesciencelessons]

Yes they are specifically written for the AQA specification.

Is it just me or has the tune at the end gotten stuck in anyone elses head?

[@soren6294]

do higher tier students need the triple content (i'm doing aqa by the way)?!?!?!

[@randomuser9634]

if you’re doing triple science then you need to know the triple content. if you’re doing combined higher then no you don’t need to.

Do we have to memorise the names of the fertilisers and their symbol equations because there is soo many of them

[@fireemperorzuko8756]

I don't think we have to know about the symbol equations(but I'm unsure) but sadly we do have to know about all the fertilisers

[@smashbros163]

hate this with a passion, here to get that final bit of remembering of it in, just to forget tommorow probably

Why do you produce crystals? That isn't in the text book

[@Freesciencelessons]

Fertilisers are delivered to farms as solids (crystals) rather than solutions.
