That's a part of life. Time resolves all. There is no way to stop it. Whether you like it or not, everything has to come to an end. And that's what destiny is all about..........

balance equation, help me...

SSV

2 H202 + H2O ---> O2 + 3 H2O

thx

SSV

[quote=棉花糖糖]thx[/quote]

No problem. Actually, that's all I know about chem.

[quote=棉花糖糖]they will be all over when the time comes~ that's what happen to me today, after finishing 4 test is such a relief...[/quote]

I understand your feelings, but I really want you to re-consider your attitude towards your teachers. You should always respect other people, no matter how depressed you are. School isn't all about studying, learning how to be a respectful person is also a part of its objectives, don't you agree?

balance equation, help me...[/quote]
the catalyst would be MnO2??:015: sry, cannot remember:014: luv chemistry in HC:027::027: used to join the chem competetion:037:  memorable days~~:018:

en... suppose to be a liver enzyme for tha catalyst... not really chemisty, half half, it's bio chemisry, bio as the main course

also a bio fan here:027: suppose the chem equation as a maths formula~~like this, then u can solve most equations~~:037:

balance equation, help me...[/quote]

Candy, are you sure this is the actual formula that you get? Because I am pretty sure there is no way to balance this equation.:030: Why this formula have the same substance (H2O) at REACTANCE side AND product side?

I suppose the reaction that you want is this:

xxxxxxxxxxxxxxxcatalyst
2H2O2 (aq) ----------------> 2H2O (l) + O2 (g)
Ps: the "aq" represants the auqiues solution. (which means the solution that substance dissolved in the solvent and has certain concentration.)
"g" means the substance is in gas form.
"l" means the substance is in liquid form.

yea right~ that's what i thought too.. can't balance it...
its ok now, hand in the assignment already~ - -
