Use the tabulated half-cell potentials to calculate the equilibrium constant (K) for the following balanced redox reaction at 25
o-na [289]
The equation Eºcell = 0.0592/n logK must be used to find n and also Eºcell 
2 Al(s) + 3 Mg2+(aq) → 2 Al3+(aq) + 3 Mg(s) Al3+ +3e- --> Al Eº = -1.66 V Mg2+ +2e- -->Mg Eº = -2.37V 
To balance the equation, 6 moles of electrons must be transferred (2 Al and 3 Mg). This will be the value of n in the equation. 
To find Eºcell, you need the reduction potentials which should be given in a table, and given above. Eºcell = -1.66 - (-2.37) = 0.71 V log K = Eºcell x n/0.0592 = 0.71 x 6/0.0592 log K = 71.95 K = 10^71.95 K = 1.1x10^72

____H3PO4 + ____ KOH --&gt; ______K3PO4 + ____H2O can someone please balance that chemical equation?
Murrr4er [49]

Answer:

H3PO4 + 3KOH ----> K3PO4 + 3H2O

Explanation:

The valency of K element is + 1 while that of PO4 compound is -3

Hence, at least 3 K atoms are needed to combine with PO4 to form K3PO4 compound.

Hence, the revised equation will be

H3PO4 + 3KOH ----> K3PO4 + 3H2O

Now, the number of atoms and charges of each element is a given equation are equal on both the left and right hand side.
