i like it i have a question can i put oxygen in the react side

[MrNick11177]

@Diegochiva0825 Hi diego. No you cannot because there are already four oxygens on the reactant side, and you have none on the product side, so it is the product side that is imbalanced not the reactant side. Which is why I put 4 H20 molecules on the reactant side...Hope this helps

i thought this was a khanacademy video. i was disappointed when i found out it wasn't. but then i watched it anyways and it was really helpful. then i was happy.

so thanks : )

Our professor went over this very quickly to cram it in before our Final. Your video really explained it well. I might have a shot at it now.

Thanks!

@ghosts897 because after he he added the hydrogens, that's 8+ and 1- charge (from the manganese oxide, i believe it would be called). so the charge for that whole side is +7. i was confused at first too cuz i thought it meant the charge for that polyatomic ion was +7. u probably figured it out since u posted a month ago, but other ppl might see this :)

I feel like I kept hearing a heartbeat or something.

very helpful! thanks so much!!

@Diegochiva0825 you can only add a H or H2O

[ghosts897]

Why is it +7 @3:22???

@bok342 how ?

[bodomguitarguy]

how do you know what the charges are?

okkkkk

@Kidwai03 you're wrong.

the hyrdronium ion H3O+ is an important part of acid-base reactions,

it is a commonly used ion, and they're is no imblance, as it is a + ion not a neutral ion

so the end is 100% correct

thanks this is majorly helpful!
