1. A 150 g piece of iron was heated to a temperature of 47°C and then placed in contact with a 275 g piece of copper at 20°C (CP = 25.46 J/(mol · °C)). What was the final temperature of the two pieces of metal? 2. If 5750 joules of energy are added to 455 grams of granite at 24.00 °C, what is the final temperature of the granite? Cs granite is 0.79 J/g oC.

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

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.

it should be all of them because it asks if you included all of those in your answer
