A beaker with 150 ml of water is placed on a hot plate. The beginning temperature is 22 oC. After 5 minutes the temperature is 87 oC. What is the amount of thermal (heat)energy absorbed by the water. 150 ml = 150 grams specific heat of water = 4.184 J/goC. show work plzzz

The amount of thermal energy absorbed by the water : Q = 40,794 J

Given

150 ml water

Temperature = 22 °C to 87 °C

specific heat of water = 4.184 J/g°C

Required

Heat absorbed

Solution

Heat can be formulated :

Q = m.c.Δt

Q = 150 g x 4.184 J/g°C x (87-22)

Q = 40,794 J

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.
