One point that is not true is an electron orbital has the same amount of energy in all orbital.
hope this helps!
Oxidation is a process in which electrons are lost from the substance. Since electrons are lost, oxidation state increases.
In the above reaction, we can see that oxidation state increases for Mn from 0 to +2. That mean Mn is undergoing oxidation.
We have
The oxidation state decreases for Cu, that means Cu undergoes reduction.
The formula to calculate cell potential is
Let us plug in the given Eox and Ered values.
The overall cell potential is +1.52V
The amount of heat energy added to silver to heat it from 25°C to 100°C is :
8737.5 J
<u>Given data: </u>
mass of silver ( m ) = 500 g
T1 = 25°C
T2 = 100°C
s ( specific heat of silver ) = 0.233 J/g.c
<h3 /><h3>Determine the amount of heat required </h3>
Applying the formula below for heat ( Q )
Q = ms * ΔT
= 500 * 0.233 * ( 100 - 25 )
= 8737.5 J
Hence we can conclude that the The amount of heat energy added to silver to heat it from 25°C to 100°C is : 8737.5 J.
