Answer:
Halogens have 7 valence electrons.
Explanation:
They are the most active non-metals including fluorine, chlorine, bromine, iodine, and astatine
Cd2+ + 2Hg Cd + Hg22+. Both Cd2+ + 2e Cd(s) -0.40 and Hg22+ + 2e 2Hg(l) 0.79
A chemical reaction known as an oxidation-reduction (redox) reaction includes the exchange of electrons between two substances.
Any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by acquiring or losing an electron is referred to as an oxidation-reduction reaction. Decomposition Reaction is one of the several redox reactions.
This is the redox reaction's overall cell potential. Cd2+ + 2Hg Cd + Hg22+. Both Cd2+ + 2e Cd(s) -0.40 and Hg22+ + 2e 2Hg(l) 0.79
Reduction describes the increase in electrons. Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another.
Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.

Answer:
All solutions are mixtures because it is two or more substances mixed together.
Explanation:
When is a mixture considered a solution.
Tyr is the answer im pretty sure at least
I don’t know but I hope you do whatever you want in life
