Double decomposition (precipitation) these involves mixing two soluble compound which involves the exchange of radicals between the two soluble salts to produce a soluble salt and an insoluble salt e.g AgNO3+NaCl>>>> AgCl+NaNO3, so both silver nitrate and sodium chloride are soluble salts which exchange radicals to produce insoluble silver chloride, and soluble sodium nitrate.
what a breakdown. i loved it. thank you guys. you are doing a great job
Glad you enjoyed it!
Thanks you are loved ❤
Most welcome 😊
I love ur explanation sir
Glad to hear that, enjoy.
Thanks
Welcome
2:42 it's A salt added on the road reduces freezing point ,and Increases boiling point
What is the difference between freezing point and melting point, he is correct impurities lowers the melting point and increases the boiling point..
he's right 👍🏾@@FrancisOnochie-i1w
Sir please be active.🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿🙏🏿
Sir... According to google, question 2 salt is used to raise the melting point not reducing
Option A is correct, an impurity lowers the melting point of a solid, check understanding chemistry (page 23).
Nice one sir
So nice of you.
THANKS SIR LEARNING WITH U IS GREAT ❤😂
Welcome.
Sir in No 22
your steps are wrong but your answer is correct
Thanks🎉🎉🎉
Welcome 😊
Sir why is the oxidation number of Na,1
It is because sodium has 1 electron on its outer most shell which it can easily give out during chemical reaction.
Sir why is the oxidation number of Na ,1?

Hello sir
Why is it 2F that will liberate 1 mole of zinc
I thought it is 1 mole for 1 faraday
Why is zinc different
Question 25 please 😢
The reason is because zinc is a divalent element.
The number in front of sodium have affected everything in that compound
Drop the question number.
sir no 21 i don't understand your explanation on why it is not C
Double decomposition (precipitation) these involves mixing two soluble compound which involves the exchange of radicals between the two soluble salts to produce a soluble salt and an insoluble salt e.g AgNO3+NaCl>>>> AgCl+NaNO3, so both silver nitrate and sodium chloride are soluble salts which exchange radicals to produce insoluble silver chloride, and soluble sodium nitrate.
@@MyschoolNigeria thank you
Welcome.
Sir please check no 5
What is wrong with the question?
But sir in no 13 you said sodium aluminate will remove large particles A , buh you said the answer is C
It was a slip, it's fine particles, thanks for your observation.
Oxygen is 3in the product side
Drop the question number.
🔥🔥🔥🔥🔥🔥🔥
Option A is Y not Z
What question number?
It talk about the mass number
Sir carbon there is 2moles not 1
Drop the question number.
It is the number of hydrogen not carbon and it is 1
Like in terms of balancing the equation
Sir I think question 5 answer is A 243.75cm not B 369.23cm
It's correct not A
Why do you think so?
@@MyschoolNigeria sir what u solved is correct because if we substitute using the Boyle's law formula we will get the answer we got in B
Exactly.
The answer is correct

It is because sodium has 1 electron on its outer most shell which it can easily give out during chemical reaction.
