Well, gee.
If it doesn't help, ask for clarification (here or there) .
Check ChemBuddy page on the half reaction method.
Yes, you should split.
Cl - is just a spectator and doesn't change during the reaction .

Hi guys i'm studying about general chemistry in a physics class.
I've some exercices that i'm unable to solve, stuff like this:
Copper can be solubilizated in water, oxidating in Cu++ form, reacting with HCrO4- in an acid enviroment realized by H2SO4 ...

equation is good, but if your teacher wants to have the original chromic acid as reactant, use that half.

I'm studying for my college entrance exams, and in the prep book there's this equation:
HCOOH + [Ag(NH3)2]OH = Ag + (NH4)2CO3 + NH3 + O2
And I'm having no luck at all with it. Can anybody help me balance it and write down redox equations.

C 3 H 8 O + CrO 3 + H 2 SO 4 = Cr 2 (SO 4 ) 3 + C 3 H 6 O + H 2 O
I've balanced this equation for mass and this was the result:
3 C 3 H 8 O + 2 CrO 3 + 3 H 2 SO 4 = Cr 2 (SO 4 ) 3 + 3 C 3 H 6 O + 6 H 2 O
I was wondering how this would be done using the...

4 2- will not used in the equation, because in sulfuric as well in the chromiumsulfate.

Hello, I was just wondering if I could get some help balancing chemical equations because I honestly don't get it at all. Thanks!
Example: (the numbers after the elements are subscripts)
KClO3 ----> KCl + O2

But we.
* (2)= 6 O
It's the balanced equation
If it's a complex REDOX reaction, you have to do it in a very with doesn't match the amount we start with?
To balance the equation we have to fix that.

I need to build voltaic cell with maximum power output.
I am using Mg2+, Cu2+ in my redox reactions.
According to Nernst equation, the cell voltage E will be:
E = 2.71 + 0.0296 * log( [Cu2+]/[Mg2+] )
But based no this, I can make the ratio [Cu2...

The Nernst equation gives the voltage.
It *is* the open
circuit voltage.

<dangerousb...@gmail.com
So Nernst equation says higher [Cu2+]/[Mg2 that there are practical limits.

Write ICF table (Initial, Change Final).
Then write overall balanced Redox equation.

For a balanced chemical reaction;
aA + bB ↔ cC + dD,
where the values: a, b, c, and d are any set of stoichiometric
coefficients which balances the chemical equation,
∆G = RTln(Q/K).
∆G is the reaction Gibbs free energy change per: c moles...
