2.
Calculate the heat of reaction for the following process:
3 FeCl2 → Fe + 2 FeCl3,
given the following info:
Fe + 2HCl → FeCl2 + H2H
2 Fe + 6 HCI → 2 FeCl3 + 3 H2
1822
AH = -769 kJ
AH = 41822 kJ
3. Calculate the heat of reaction for the following reaction:
Fe + 2 Agri → 2 A Coru

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
