Question

Balanced equation for 2H2O + O2(g)

Answer 1

@Elsa213 are you or anyone you know good at Chem? xD

Answer 2

I can try helping.. o:
What's the questions and does it have answer choices?

Answer 3

Well, it just asks for the balanced equation for hydrogen peroxide --> oxygen gas + water

Answer 4

So no answer choices? e.e

Answer 5

Sadly, no ;-;

Answer 6

Dang et ;~;

Answer 7

I know right ;-;

Answer 8

@AloneS e.e

Answer 9

As far as I know @Jamierox4ev3r AND @brittanyrolfe are good at Chem! :D

I hope one of them tries to help ;3

Answer 10

Okay :)

Answer 11

Hello! This shouldn't be that difficult, I don't think

Answer 12

So this is a decomposition reaction, since you have a compound breaking into smaller components.

Answer 13

So thus far,

\(H_2O_2\)-->\(H_2O+O_2\)

Answer 14

Now all we have to do is add coefficients to make sure the equation is balanced

Answer 15

\(H_2O_2\) -->\(H_2O+O_2\)

**2 H **2 H
**2 O **3 O

There's one extra O here. So where would be a good place to add coefficients and make things even? @Valirium

Answer 16

Uhhh on the left side? o.o

Answer 17

That's one of the places you'd add a coefficient

So it'd look like this

\(H_2O_2\) -->2\(H_2O+O_2\)
**2 H **4 H
**2 O **4 O

So where's the last place you need to add a coefficient? You're so close!

Answer 18

Would it be on the right? e.e

Answer 19

Correct! So based on that, what would your final balanced equation be?

Answer 20

I'm not good at this part ;-;

Answer 21

No worries, you basically got there :)
Here it is:

\(2H_2O_2\)-->\(2H_2O+O_2\)
**4 H **4 H
**4 O **4 O

See how everything is even on both sides. This is your balanced equation.
Does that make sense?

Answer 22

Ohhh! It does. Thank you for helping! :)

Answer 23

I'm glad it helps :) See you later
