Iron having Z=26 with electronic configuration as has 6 electrons in the 3d shell wherein 5 electrons are aligned parallely and 1 electron as antiparallel.
having electronic configuration as
has 5 electrons, all aligned in the same direction.
Iron, when kept in external magnetic field, the magnetic domains of the atom get aligned in one direction that means it becomes parallel and they remain parallel even after removing the magnetic field therefore, it is considered as ferromagnetic.
Answer: 47.276 kJ/mol
Explanation:
According to Gibb's equation:
= Gibbs free energy
= enthalpy change
= entropy change = +106 J/mol
T = temperature in Kelvin = 446 K
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
(1kJ=1000J)
Thus the value of ΔH = 47.276 kJ/mol, assuming that ΔH and ΔS do not vary with temperature.
Answer:
Explanation:
We know that the speed of light is equal to
We need to find how far the light travel in 3 days.
Speed of an object is equal to distance covered divided by time taken.
Also, 1 day = 86400 s
3 days = 259200 s
So,
So, the light will travel in 3 days.
