I NEED HELP ASAP I WILL GIVE Is a chemical reaction taking place during Xavier’s experiment? How do you know?

Baking soda is used in cleaning, deodorizing, and baking. When citric acid and baking soda react with one another, they change chemi- cally and form sodium ions, citric acid ions, carbon dioxide gas, and water. ... Carbon dioxide gas is safe in the quantities produced in the activities.

hope i helped

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 would be a gas formation
