So in 13 if it was *mass of zinc only* D could’ve been correct right?
This helped me so much thank you
Exam is in 3 hrs
Salam Writing my 0620 alternative to practical today Hope its easy
October 2024 here 🤣🤣 hope we all score A* 🤲
😭😭📍📍📍
@@EyadHatim my exam is in 3hrs and 30mins, i hope this video helps me😂😂
SAMEEE
Samee
GOOD LUCK EVERYONE ❤
THANK YOU SO MUCH DR MONA❤️❤️❤️
tomorrow.
Why can’t we say in q2fii that pipette measures a fixed volume of 25.0cm3 only....just becz sodium thiosulfate was 5 cm3 in all previous expirements
I think you're referring to a volumetric pipette. A normal pipette is much smaller
I have paper 6 in 3 days, any tips ?
SAME i feel so stressed
Read every word.
How does nitrogen have 5 outer electrons because it has 4
و عليكم السلام ورحمة الله
thank you so much
If i put ph 13 for strong alkanie would it be correct??
3 days
Hey miss mona I hope you're doing fine isn't the graph should've been a little bit wider because it should take at least half the graph?
Eternal thanks for your life saving videos ma'am! 💕 I do not understand Q 12 at all .. How is it endothermic ( temperature of th mixture falls and if so delta H must be negative (R <P) ? Can you plz elaborate ??
@@mrbeanchannel5541 Endothermic reaction absorb heat energy from the surrounding so the temperature of the surrounding decrease . the Delta H is positive because the energy absorbed to break the bonds is greater than the energy released .
Thank u so much for the explanation!!!❤❤
Asalamualaikum waramatullahi wabarakatuh. JazakAllah Khairan. May Allah reward you for helping us increase in beneficial knowledge.
Ma’am in 3 d , I wrote increase concentration and pressure and temperature at 3rd but I cut it (it was in the 3rd extra row under the second one) . Will a mark be deducted ? Since only uncut answers are pressure and concentration. Does this mean I can’t get international distinction anymore , since all of my paper was correct excluding this ?
helpful af
Good explanation 🩷
I got 40/40 in this paper in my external and 193 in chemistry as a whole thanks to you. Your videos are very helpful and can help anyone get an A* in chemistry. Again thank you so much
JazakAllah khairan
Wow,,thank you,,, I'm going to write tomorrow ❤❤❤
Miss can use larger and darker arrow in your newer videos
is q6 out of the syllabus for this year?
Thank you for all these videos these help a lot 🙏🙏
For question 24 how do u find out the oxidaton states?
dr.mona, why is it c=c and not c-c like the formed bond ? whats the difference? 10:18
ethene ( alkene) is the reactant . Which has c=c. And ethane (alkane ) is the product. Alkane has only single bond between carbon atoms
for question 2)f), why do they specifically talk about the acid only? experiment 1 also has the same mass of calcium carbonate as experiment 2
why is potassium bromide in question 7)i) colorless and not white
All group 1 compounds are white solids that dissolve in water to give colourless solution.
ahh i see thank you!
q10, you said Fe2O3 has 5 ions in one mol of Fe2O3. then wouldnt it be just 5×0.25?Sorry im confused ive never calculated number of ions before
so 1mol has 6.02×10^23 ions or 5 ions??
1mole has 6.02×10*23 formulas and each formula contain 5 ions
how to know BaSO4 is white and CuSo4 is blue? do i just memorise? i find alot of questions talking about the color of compounds and im pretty confused because ive never learnt about the colors. Is there specific compounds or elements that i have to memorise their color?
yes in chemistry we hv to memorise the colours, u can search in ur textbook (usually the last chapter) or search online :)
can you please do paper 3 too
why bcant 14 be A when oxygen reacts w electrode
Thank youuu
aiming for 30+ inshallah
shouldnt Q10 be D? since if it is C then chloride should be formed at the anode not oxygen
@@xx-zp4or It’s mentions “dilute”. If it’s a dilute aqueous solution, then the products will ALWAYS be hydrogen (at cathode) and oxygen (at anode), regardless of a halogen present, or a lower reactive metal than hydrogen.
The answer is C: Halogens only discharge if the solution is concentrated. In case of diluted solutions (OH)- ions are attracted to the anode and oxygen gas discharge instead . (D) is wrong because it's molten potassium oxide . Potassium will form at the cathode and oxygen at the anode. If a metal less reactive than hydrogen is present it will be discharged instead of hydrogen
Yesss :)
Tomorrow is my paper hope I'll get 30🥺❤️
ISA you'll get a higher mark
hope u reach 100k subs soon!
thank you
can u pls help me i can’t memorize the qualitative analysis and i have my exam tmrw 🙏🏻💀
why cant question 35 be B?
Because bromine has to be added in 2 adjacent carbons (two carbons that are next to each other ) and that is not happening in ( B)
@@DrMonaSeif thanks, is that the rule for most addition reactions?
@@Channels208bromine is added where the double bond breaks so it means it must add across two carbons next to each other . Apply this logic wherever needed.
@@xdSloshy thx
Are yall having multiple choice in 1.5 hour like i am, if so, good luck yall
Ma’am why can’t 20 be A?
Because calcium sulfate is an insolable salt so it cannot be prepared by the excess method (adding carbonate to acid) Insoluble salts are made by precipitation reactions
@@DrMonaSeif doesn’t A produce the same salt?
Calcium carbonate reacts with sulphuric acid to produce calcium sulphate but because calcium sulfate is insoluble so it will Precipitate over the crystals of calcium carbonate prevent further reaction that means the reaction will stop so calcium sulfate cannot be prepared by this method
How do I know in 11:05 when it’s single or double bond?
In question 20, please explain why carbon monoxide is of course neutral...I think to be a great teacher, it is significant to explain even though it is obvious for some students who might have difficulties to comprehend. So please don't say the phrase 'of course' and explain..........
The oxides that react with water to form acid or oxides that react with a base to form a salt are known as acidic oxides. The oxides that react with water to form a base or oxides that react with an acid to form a salt are known as basic oxides. The oxides which neither react with acids nor react with bases are known as neutral oxides. The oxides which react with acids as well as react with bases to form a salt are known as amphoteric oxides. Carbon monoxide neither reacts with acids nor reacts with bases. Thus, carbon monoxide is a neutral oxide.
can you explain more for question 19?
*A is wrong:* It describes an acid-metal reaction, not an acid-base reaction. *B is wrong:* It describes a precipitation reaction, not an acid-base reaction. *C is wrong:* It involves a base and a salt to form a precipitate, but it is not a direct acid-base neutralization reaction.
in 17:40 how is the boiling point increasing down the group? its clearly decreasing is it not. ur answer is correct via ms but i dont understand the bp part
The value of the negative number increase as the number gets smaller
do you understand math.
11:40 how does it mean endothermic when the temperature falls? isn’t it supposed to have higher temperature as it absorbed energy and the surrounding temperature must be lower?
Endothermic reaction absorb energy from the surroundings so the temperature of the surrounding falls (decreases)
@@DrMonaSeif yes, so the temperature of the *surrounding* falls, not the mixture and that’s my point
dr mona, can u pls tell me which metals react with cold water and which metals react with steam, because this reactivity question really confused me 19:49
Group one metals react with water to form metal hydroxide and hydrogen gas magnesium reacts with warm water or steam .
@@DrMonaSeif just magnesium from Group II ??
