Which of the following is the most wasteful use of water? taking a shower rather than a bath watering the garden with recycled water running dishwashers before they are completely full replacing high-flow showerheads with low-flow showerheads

Option (c) is the correct answer.

Explanation:

Wasteful use of water means using water unnecessarily or without any need.

So, when we take a shower rather than a bath then it means we are using water for bathing and not wasting it.

Watering the garden with recycled water is also not wasting of water as we are reusing the used water.

Running dishwashers before they are completely full is a wastage of water because unless the dishwashers are not completely full the water will flow out and it is a wastage of water.

When we replace high-flow shower heads with low-flow shower heads then it means we are minimizing the flow of water and it is a conservation of water.

Therefore, we can conclude that out of the given options running dishwashers before they are completely full is the most wasteful use of water.

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.
