This guy taught me more in 5 minutes than my teacher did in 2 hours. You Sir are a legend👊🏻

[@3lla_.xinett94]

I got an 8 in the Biology mock exam because of you, so much content in a 4-5 minute video, brilliant! I've told everyone about you, best teacher by far. Thank you so much for you help, I don't know what I would do with out you!

[@yerboi9223]

you are honestly without the shadow of a doubt the BEST person in the world I am revising for mock GCSE's and I found you and you are just the BEST. You are a teacher who instead of teaching 1 class you have gone on to Teach over 30,000 people(you subs.) Please don't stop making these videos...

YOU ARE ACTUALLY SO HELPFUL... WAY MORE HELPFUL THAN MY SCIENCE TEACHER

[@Erinloombands]

I just want to say, thank you so much. I have spent two weeks in science class not understanding how to do these, I then watch your video and learn this skill in ten minutes. Your videos are so helpful

[@archivedaccount2000]

thank you sir, thanks to your videos and my textbook I was able to teach myself / fully understand the physics and chemistry GCSE course - I got a 9 in both (an A* in the old system). respect that you provide these services for free

[@terabaaphun2903]

wow

[@Careditinghub]

All of the dislikes were from the Chemistry teachers who realised that their students were learning more from a 5 minute video than 2 weeks of their teaching.

[@TheDelaneyCurry]

I spent way too long trying to figure this on my own. Wish I had found your video earlier! Well done! 👏👏👍👍

[@Ab-kx4xv]

Thanks for the last day revision. My mock in chemistry is tomorrow, and after watching about five of your videos, I feel confident. Keep up the hard work. You are a huge help.

[@maxburnett7724]

You are honestly a life saver , i have been trying to learn this for weeks... but you managed to teach me in a matter of minutes thank you very much

ive had so many issues with my school trying to keep science teachers and seriously, im learning stuff now from these videos, thank you so much

[@chiamakaobih7508]

Just imagine! After going for night class, didn't get an atom of what the teacher said for hours. And here's a man explaining it in 5mins and I understand perfectly. Just wow!

[@lilliancox6719]

Thank you so much, this is the first time I've properly understood this. You make difficult topics finally make sense, thank you for your videos they've helped me so much :)

[@ferdinandzoettl9331]

Can't thank you enough. I don't think my chemistry teacher has properly explained this once, and when he does he just glosses over it quickly in tiny illegible handwriting on a whiteboard, I now understand this topic and am ready for my test.

[@saturn3018]

I was just sitting in class not understanding how to do this for ages and now I finally get it!! thank you freesciencelessons 💕

Hey FreeScienceLessons I love your videos, they really help me understand science! Keep making more like this!

My GCSE is tomorrow morning and you have helped me sooo much. No one i have asked has been able to show me how to do this properly and i was very close to giving up. Thank you a million times over!!!!!!!!!!!!!!!!!!

[@paddingtonbrown2181]

This man taught me this whole thing in two minutes and my teacher couldn't do it in an hour. I had a very important assignment on this due very soon that I had no idea how to do but this taught me how. If you're still reading these comments, then thank you so much.

how do you work out the relative formula mass? for example at 5:06 how did you get 100?

Hello, I just wanted to thank you for all the videos you've been making. I took my GCSE's in 2016 and your videos are the reason I went from a low B to getting full UMS on all 3 papers for my further additional science GCSE. I got 395 UMS out of 400 (a very high A*), and it is mainly thanks to you. Please never stop what you are doing because it's helping year 11 students so so much. I can't thank you enough!! :) x

[@user-eg9kb3up8q]

In the exam, would we be expected to know that sulphuric acid is H2SO4 etc. (3:13) if it was given in a word equation. Or do they tend not to use word equations in questions similar to these?

4:13 why do we not include the hydrogen when calculation the Mr since would it not change the calculations to 138 since 1 times 2 is 2

[@Freesciencelessons]

The question is only asking us to calculate the mass of the calcium sulphate so we do not need to think about the hydrogen at all. Hope that helps.

What is : copper oxide is is reduced by excess hydrogen. Calculate the maximum mass of copper that could be obtained from 79.5g of copper oxide

[@vybz987]

Half my work for this home learning term didn’t send and theres no record of me doing it, never been so stressed

[@yhp6266]

at 3:08 how did you get 95 when multiplying it by 3

[@Freesciencelessons]

95 is the relative formula mass of MgCl2. Mg has a relative atomic mass of 24 and Cl has a relative atomic mass of 35.5. There are two atoms of Cl in MgCl2, so we need to multiply 35.5 by 2 to get 71. Adding 24 + 71 gives us 95. We multiply 95 by 3 because there are 3 moles of MgCl2. This gives us 285g as the answer.

Okay so, we are currently doing this in class and my teacher says that we don't learn moles until year 11, and we are learning this. I literally can't describe how confused I currently am since we use a different method but I find this on way easier???

[@joudalhussain943]

Hi Sir, thank you a lot! But how do we find out the minimum mass when the reactant has fully reacted?

[@ina4488]

At 4:04 I got 98 instead of 136. I did 2+32+64. Please could you tell me what I've done wrong

[@Freesciencelessons]

You need to calculate the Mr of the product which is CaSO4. You have calculated the Mr of the reactant H2SO4.

[@ina4488]

Freesciencelessons Oh! Ok, thank you! This is why you don’t revise until 11 every day!

[@simonday1040]

how did you calculate the Mr at 4:40 for the calcium carbonate??

[@Freesciencelessons]

Add together the atomic numbers for the atoms of the elements. Ca=40, C=12, O= (3x16)=48. 40 + 12 + 48 =100

[@milliebutton4385]

My teacher tried to teach this to us and definitely failed. Thank you so much though I’m still confused slightly I’m definitely learning it now thank you so much
