Hello, I am from India. In our NCERT science class 10 textbook(the book which is officially published by our Education board) this reaction is asked as a question and that question is unanswered. Very few teachers tell about this and we students are left curious without any answer but this video helped me a lot to understand this reaction. Thanks a lot!!!!
@@khatti-meethizindagi7300 It's because heat energy was absorbed from the surroundings, which reduced the temprature around the beaker and caused the water beneath it to freeze
This was really helpful! I was struggling with this question for a very long time...now I understand what really happens. Other sites byjus brainly etc. we're not telling exactly about the reaction and observation.
Thanks for this awsome video, I was doing some homework and one of them was asking if this reaction absorbs heat or releases heat. this video came in really handy xD
Hi! Awesome videos! May I use this video for an Instagram post to explain how to use the Gibbs Free Energy equation in a qualitative way? If so, how can I refer to the video? Thank you!! :)
It has absorbed energy from the surroundings-the water below the beaker hence it got freezed and sticked to it as it absorbed it's latent heat and changed its state.
even though we have not applied energy in the reaction... the reaction has taken the energy from its surroundings... Endothermic doesnt necessarily mean that energy needs to be applied from us... it only means that in the reaction energy is absorbed (somehow)...
i would like to know how much time is it take to the solution (cooling experiment) to come back to room temperature? and if i try to stir it again would it become cooling again? or if i always stir would it stop fooling? thanks a lot and waiting for your answers.
the energy goes from the water to the powder. It was an endothermic reaction, which absorbs energy. You probably know this by now tho. (ten month difference)
An endothermic reaction is a reaction that is followed by the absorption of energy (in this case, heat). Since the energy is absorbed from the surroundings, the temperature drops below -0 degrees Celsius and the water on the block freezes. The energy that was absorbed was used for the chemical reaction.
@Lilly Chan Actually you should react 5.3 grams of ammonium chloride with 17.1 grams of barium hydroxide anhydrous, 18.9 grams of barium hydroxide monohydrate or with 31.5 grams of barium hydroxide octahydrate.
@@berreyl1689 nope, freezing is endothermic. this is because all the heat is absorbed and it becomes very cold. heat is energy and energy is absorbed. hence the reaction is endothermic.

I'm here for the same thing
same
@SHREYA SINGH It is bro, actually
But still Hi-five
Hey can anybody tell me how is this reaction endothermic????

Anyone else here for Chemistry, in September 2020?

Thank you ! This video helped alot 👍
Anyone else here bc school >:v
Thanks for including the equation
Thank you
Amazing just amazing chemistry is all about wonders🤓

Thank you!! :)
could this work without stirring if it was crushed up more/diluted? asking for a science project
Thanks
How are you going to take it off the block?
How are they reacting if they both are in solid form?
How is it endothermic , did we used any heat or sunlight or electricity to make them both break down or whatever lol ..
Is this rxn considered mechanochamical?
THATS SO COOL
Any idea how long does this reaction last..
May I post your video on my Google Classroom for my highschool students
sure go ahead
Due to the covid-19 I cannot do the demon myself
حلووو nice
Thanks it made me understand this reaction better
😂
7 saal ho gye abhi aap kya karate ho😮
Amazing reaction
var halpful vedeo
Ncert class 10 😅
WHAT THE HELL SO COOL MAN
bro...That was awesome lol
Epic video!!!
Who want to become a scientist
Because We all like to see or do experiment 🧪
It's a exothermic or endothermic
Endothermic
Chem 154 anyone?
Is it the same effect using Ammonium Nitrate or Ammonium Thyocyanate?
Well i had tried it yeah it is😀
Which compound forms the precipitate in this reaction?
There is no precipitate formed in this reaction
Why this reaction is endothermic? we have not applied any energy on it during reaction please answer
im also confuse
It has absorbed energy from the surroundings-the water below the beaker hence it got freezed and sticked to it as it absorbed it's latent heat and changed its state.
even though we have not applied energy in the reaction... the reaction has taken the energy from its surroundings... Endothermic doesnt necessarily mean that energy needs to be applied from us... it only means that in the reaction energy is absorbed (somehow)...
can i use barium hydroxide octahydrate and ammonium chloride to fin the same result
i meant **liquid barium hydroxide
@@moatasemnada2696 yes you can... The reaction then becomes:
Ba(OH)2 + NH4Cl --> H2O + NH3 + BaCl2
i would like to know how much time is it take to the solution (cooling experiment) to come back to room temperature?
and if i try to stir it again would it become cooling again?
or if i always stir would it stop fooling?
thanks a lot and waiting for your answers.
idk man
which direction does the energy go?
the energy goes from the water to the powder. It was an endothermic reaction, which absorbs energy. You probably know this by now tho. (ten month difference)
@@raimundwarbasse6031 thank u lol but i already passed the class 🙏
@@saladbonka Had a hunch about that, hope you go to great places in life after school!
Why would the temperature of the products drop?? shouldn't the products have more energy in an endothermic reaction??
An endothermic reaction is a reaction that is followed by the absorption of energy (in this case, heat). Since the energy is absorbed from the surroundings, the temperature drops below -0 degrees Celsius and the water on the block freezes. The energy that was absorbed was used for the chemical reaction.
Science at newman? Anyone :)
Hellloo tenthies!!
This reaction is exothermic or endothermic?
From what i understood it is endothermic
It is endothermic reaction
Nano
Do you ever reply...lol
So it is endothermic reaction.?
+Unnati Dakoria Yes, yes it is.
5 years ago GG
wait isn't freezing exothermic reaction?
@@berreyl1689 wtf
@@berreyl1689 No lol
what is the measurements of the substances?
whats a gm?
BattleBunny grams
@Lilly Chan

for good results try 11g Ammonium chloride and 32g Barium Hydroxide
@@arancienne how did you come up with your amounts I mean how do you know that this is going to give good results just curious
boys is this endo or oxothermic. asking for a friend
Haha this is an endothermic reaction :)
