In this video, you'll learn how to predict the products of double replacement or double displacement reactions. We'll start with the basics of what double replacement reactions are and then go through three examples together step by step.
Double replacement reactions involves two ionic compounds or ionic-like compounds, such as acids and bases, reacting with each other. The products are two new ionic compounds. In a double replacement reaction, the cations essentially switches places with each other. You can also think of the anions switching places with each other. Both perspective is correct.
The best way to approach double replacement reactions is to first label the charges of each of the ions in the two ionic compounds.
By the end of this video, you'll know exactly how to predict the products of double replacement or double displacement reactions.
Teacher: Teaches something
*I don't understand*
UA-cam teacher: teaches something
*I now understand*
This is literally saving my life the night before a quiz.
This is saving my life just before a checkpoint examination
@@zahirulises5205 you have to pay $11 dollars to get the access code bruh
HAHHA SAME
It's saving mine 20 mins before a quiz im at lunch then we starting😭
Good
But try not to read a night before a quiz
This is BY FAR the easiest method I've seen so far. Saving my ass before a big quiz. The way you explain it is so much simpler than any other video I've seen
Why do u bring over some subscripts and not others? And how do u know which ones u bring over n which ones u don’t? So confusing🤨
Ik it’s 3 years later but your cooked
Why don’t you carry over the 2 on Br?
that's what i'm asking too
@@wildmansam1Cu (copper (||) ion) so the 2 represents Cu 2+ i believe!
bromine is 1-, so on the other side it crosses (makes an X) putting the Cu charge on the correct side which is why (NO3)2 is listed
Just helped me with HW! Thanks! :D
BRO IS THE CLUTCH
Thank you 😭 I almost failed
what would the balanced equation be for the first one?
anyone else here 17 minutes before a chemistry test
Why do you take only one of each element?
Good job sir
Keep it up
my teacher must suck, because this 6 minute video jus saved my life
Sir may I ask why the last one is water instead of HOH😢😢😢😢😢😢😢😢😢😢
There is 2hydrogen and one oxygen
You simplified this 10 times better then my teacher
Can you please explain the last example? When you combined H3 with (OH)2 you got H2O. What happened to H3 and also (OH)2???
H(OH) there’s 2 H moles and idk just H2O? 😂Just try to make it make sense
The ^ symbol is to represent the symbol that follows it as superscript.
The hydrogen ion (H^+) has a charge of +1, and the hydroxide ion (OH^−) has a charge of -1. When they combine, their charges neutralize each other:
(H^+) + (OH^−) → H2O
This process forms water (H2O). Each pair of one hydrogen ion and one hydroxide ion combines to create a water molecule, effectively neutralizing the charges.
Why dont you make the charges negative on the criss cross method
how can you determine if 2 ionic compounds will react ?
Thanks a lot, sir. Today is my science exam and this video really helped me to understand what displacement reaction is. 😃
I missed a day of class when we taught this stuff and this video really helped me get all caught up. Thanks a bunch!
watching this 1 hour before my ib Chem quiz ☠️
Yo….. THIS JUST HELPED ME. THANK YOU SO MUCH!
Gotta do the balances too man, never do you not do them as well in a class
Thank-you you saved me buddy
Thank you
2nd equation agbr why not agbr2 pls explain
When you cross it over the 1 replaces the 2
You’re so fun to listen to this was so helpful thank you ;m;
TYSM FOR THIS VIDEO
But how do balance them n
My teacher had to teach us chemical reactions including s d c sr and dr in 3 days💀💀
i love you
totally saved my ass thank you
The subscript part got me sooooo lost!! It’s like ur just supposed to take a guess n bring em to other side if u want or not if u don’t want lol😆Makes zero sense tho😬
it's been a year since you posted this comment, but if there's a positive charge (say +3) on one element, and a negative charge of that positive number but negative, they would cancel each other out, therefore you don't have to write the subscripts. however, if their are two different charges (say -4 and 3) you would write the subscripts swapped out. in any circumstance of writing the subscripts, you would have to swap them out, btw. if you knew this already and figured it out, great but if not, i hope this helped!
Metal and non metal class 10th whole chapter
u have to balance
Midterm tomorrow!!!
Lets F***** go
thank you so much
Np! Glad to help :D
