1. The problem statement, all variables and given/known data CuCl 2 (aq)+Al(s)→AlCl 3 (aq)+Cu(s) 2. Relevant equations 3. The attempt at a solution I'm just not sure what to do with a situation involving compounds. I can do simple balancing without a ...

That was simple! Thank you very much, and ....
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" <dangerousb...@gmail.com So Nernst equation says higher [Cu2+]/[Mg2 that there are practical limits.

2)....
Hydrogen:oxygen (experiement) versus hydrogen:oxygen (equation).
Fe + 2Fe3 Equation Mole Ratio (of 1st reactant to 2nd reactant).
Write ICF table (Initial, Change Final).
Then write overall balanced Redox equation.
Bonjour tout le monde. je suis un peu embeter avec un exo. voila l'enoncé : on se propose de verifier la justesse de l'expression porte par l'etiquette d'une bouteille d'eau oxygénée: eau oxygénée -20volumes. pour cela on effectue un dosage de l'eau oxygénée...

equation avec solution de repondre rapidement :d Regarde ta table redox Deja fait mais la reaction sil vous plait La question est est connu pour ses propriétés ....
La constante des gaz parfaits R=8,31433, et le volume s'exprime en m 3 .
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...
