ECZ PAST PAPERS 2 FOR GRADE 12 - Science paper 2 2020 GCE Full Revision.

[@jacekyle3131]

Not to seem like am Arguing sir, but on question number 7A, section A...i think the best option is D.104 degrees Celsius reason being, when something(Sodium Chloride) has been added to water, the Boiling point increases, and its freezing point decreases,...and we call the increase of the boiling point as boiling point elevation, while the decrease in the freezing point when NaCl is added is called Freezing Point depression...Otherwise thank you very much for this video..its really helpful sir,..keep up the great work

[@THEDMSONLINESCHOOL]

You are write, at the time I was revision the paper, I did research on the answer I also wasn't sure of my answer. I will make a pinned comment about it so that everyone can see correct answer.

[@eddiek8950]

I am a teacher but if I claim to be genius then I am dull, hence I ought to have more knowledge from your powerful explanations.God bless you.

You are welcome and yes i will continue.

[@Christine-o5z]

This was helpful

[@dianakashano209]

Sorry , just to confirm on question A6. Are the other options okay because they are above 25 degrees

[@evanskrichard]

Sir I have a question.we all know that the number of electrons on the outermost shell represents the group number of that particular element, now what about helium have 2 electrons in it's outermost shell but belongs to group eight.why?

[@THEDMSONLINESCHOOL]

Because it's stable like group eight elements owing to it's full outermost shell.

[@GivenSilomba]

Those are Noble gases bro don't over think

[@ackimkanchinyi6159]

Very impressive and easy to understand

[@ProsperSuccess-f3t]

Thank you very much sir. Keep it up 👏👏 I wanted to ask for that physics pamphlet pliz i ll appreciate 😮

[@YOXENITH]

1:58:01 but it says gases. Ain't you supposed to put two gases?

[@ChandaChibuye-k5c]

Thanks for the video sir🙏the sound in the background is too loud though .

[@banistermasonde-gs4dr]

It's helpful sir

[@THEDMSONLINESCHOOL]

Glad to hear that

[@howardchisengah7187]

Redo question B4 (III) it is 0.25 × (500÷1000) = 0.125 mol. Then the final answer should be m=0.125×56 = 7g

[@THEDMSONLINESCHOOL]

I see I made an error in the value for concentration, I was supposed to write 0.25M but I wrote 0.2M which resulted in getting 5.6g. But if I wrote 0.25M, the answer was going to be 7g not 14g. 0.125 × 56 = 7g.

[@THEDMSONLINESCHOOL]

Thanks for drawing my attention to that, next I will be more conscious about such trivial errors.

[@CATHERINEDZIKAMUNENGA-xj1cd]

Sir I can't seem to find any of your maths videos

[@ednessmasebo7921]

Very helpful, thank you so much sir but the music is so disturbing.

[@kalotasaviour]

For section B4. I know that potassium is a metal but why have you stated it in (aq) state instead of (s) state. Because all I know is that all metals are in solid state

[@THEDMSONLINESCHOOL]

Maybe it was a typo error.

[@havinesskangwa8397]

Have already passed science 🙏

[@lucksonmuleya3928]

But how do we know that there is aq

[@abigirlmweemba2272]

wow you are the best

[@brendahmwala7669]

Am now understanding sir thanks

Where is your tuition centre located

[@THEDMSONLINESCHOOL]

Currently am not offering tuitions other than the lessons am offering on my channel. But I might just offer online tuitions in the coming holiday for major topics in science and maths, so if you don't want to miss the opportunity, then you might consider subscribing to my channel and hit the bell notification so that you get notified when I make the announcement. Thanks for asking ❤️❤️❤️

[@memorymakowane2443]

Ok awaiting eagerly sir ! Thank you for the response

Nice explanation

[@dannybwalya-c3x]

Thank you sir

Very nice video but am not sure on the definition of an acid I feel that a definition of salt

[@THEDMSONLINESCHOOL]

I was wrong.

[@patricialuyanga1138]

Am I join your subjects

[@NopreasterChiweshe-gy5nv]

B4 isn't correct on finding the mass

[@temwanigumbo8271]

The music is the background wasn't necessary, that's for me because it's disturbing me and I can't concentrate properly

[@THEDMSONLINESCHOOL]

Just try hard to concentrate

[@kubokochipulu4611]

Please don't add music next time

[@GiftIlyamupu]

Sir i can't understand because of the misic

[@giftmwansa-gc5vp]

i need about chemical equastion

[@THEDMSONLINESCHOOL]

[@MisheckKalunga-st7lv]

That background sound is unnecessary sir

[@THEDMSONLINESCHOOL]

Exactly

[@jacquelinesakalamwale1772]

The song is just to disturbing 🚶🚶🚶🚶🚶🚶🚶🚶🚶🚶🚶

[@JudithPhiri-rt9sz]

The music is disturbing

[@THEDMSONLINESCHOOL]

Since it's for free, you would rather appreciate than complain.

[@MaxwellZulu-ni3wd]

Hand writing is not clear

[@margretchibolya3063]

Don't be adding no music on here.... It sucks!!!

[@THEDMSONLINESCHOOL]

Mind the way you comment because your comment sucks more than the music.

[@marymutale1866]

Poor video. Musical sounds is higher than the important things needed

[@THEDMSONLINESCHOOL]

The music was high yes but so also was my voice. It's just that you don't like my taste. So yes look for a good video else where. You are not going to offer your negative comment without appreciating the effort. Next time you do this, you risk being blocked.

[@marymutale1866]

Just accept the fact. Block if you want coz I didn't insult but told nothing but the truth.
