Muscles bones no on organs and no on skin
Birds use the magnetic fields and some fish i believe as well and maybe butterflies im not entirely sure <span />
The paths in which electrons travel are called orbitals.
Answer: It is non-spontaneous at all T.
Explanation:
According to Gibb's equation:
= Gibbs free energy = +ve
= enthalpy change = +ve
= entropy change = -ve
T = temperature in Kelvin
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Putting in the values:
Reaction is non spontaneous at all temperatures.
