What?!
|
This is unbelievable. If you're good at math, then perhaps we can switch to chemistry!
|
Question 12: Balance the following chemical reaction.
|
Water will decompose into hydrogen and oxygen, but exactly how many molecules will participate?
|
A better way to say this is "how many moles, or 6.022×1023 of each molecule, will participate"?
|
So make your choice...

*Balance the following chemical reaction:
2 H2O → 2 H2 + 1 O2
2 H2O → 2 H2 + 2 O2
1 H2O → 1 H2 + 1 O2
1 H2O → 1 H2 + 2 O2
