It's saving mine 20 mins before a quiz im at lunch then we starting😭

[@peaceolufemi6149]

Good But try not to read a night before a quiz

[@ADepressedwhale]

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

[@Delulueraa]

anyone else here 17 minutes before a chemistry test

[@emmanuelabrigarde3377]

You simplified this 10 times better then my teacher

[@shaneflaherty5590]

I missed a day of class when we taught this stuff and this video really helped me get all caught up. Thanks a bunch!

Why don’t you carry over the 2 on Br?

[@wildmansam1]

that's what i'm asking too

[@user-bz8id3sz4v]

@@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

[@clytizzle6463]

Just helped me with HW! Thanks! :D

[@teiadhurup2878]

what would the balanced equation be for the first one?

[@benkhong]

Yo….. THIS JUST HELPED ME. THANK YOU SO MUCH!

[@joshuakim2695]

Why do you take only one of each element?

[@Zyloxcia]

BRO IS THE CLUTCH

[@error69420]

Thanks a lot, sir. Today is my science exam and this video really helped me to understand what displacement reaction is. 😃

[@liamdurkin7327]

Why dont you make the charges negative on the criss cross method

[@sumanmishra9373]

Thank-you you saved me buddy

[@alihussain3774]

Good job sir Keep it up

[@biaastar_]

TYSM FOR THIS VIDEO

[@a.kjfhkziujsfdgbskjxfyhgfl2332]

how can you determine if 2 ionic compounds will react ?

[@zakmatew]

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???

[@RAZORRANGERMax]

H(OH) there’s 2 H moles and idk just H2O? 😂Just try to make it make sense

[@_..D]

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.

[@k.n.i.c3826]

Thank you 😭 I almost failed

[@esthercontreras8750]

But how do balance them n

[@24karat22]

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🤨

[@EthanCahill-zn6tb]

Ik it’s 3 years later but your cooked

[@ticagamer7517]

my teacher must suck, because this 6 minute video jus saved my life

[@user-ws5co4xd2e]

Sir may I ask why the last one is water instead of HOH😢😢😢😢😢😢😢😢😢😢

[@keiraf1]

There is 2hydrogen and one oxygen

[@ruger51995]

Gotta do the balances too man, never do you not do them as well in a class

[@anandhis2507]

2nd equation agbr why not agbr2 pls explain

[@jacquelinecalixtro8403]

When you cross it over the 1 replaces the 2

You’re so fun to listen to this was so helpful thank you ;m;

u have to balance

Metal and non metal class 10th whole chapter

[@24karat22]

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😬

[@morgan.mets5700]

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!
