How would you calculate the difference in enthalpy?

1 answer:

7 0

(Biology)
Equation: (delta)G = (delta)H - T (delta)S
(delta)G stand for change in free energy. When it is positive, it is endergonic. When it is negative, it is exergonic.
H stands for bond energy and is enthalpy
T is the absolute temperature expressed in the Kelvin scale
S is entropy or disorder in the system

KMnO_4

Transition metal is Manganese (Mn)

Actually it's the oxidation number of Mn

Let's find how?

$\\ \tt\Rrightarrow x+1+4(-2)=0$

$\\ \tt\Rrightarrow x+1-8=0$

$\\ \tt\Rrightarrow x-7=0$

$\\ \tt\Rrightarrow x=+7$

x is the oxidation number
