Answer is: reducin agent in this reaction is thiosulfate (S₂O₃²⁻).
Balanced chemical reaction: 2S₂O₃²⁻(aq) + I₂(aq) → S₄O₆²⁻(aq) + 2I⁻<span>(aq).
Reducing agent is element or compound who loose electrons in chemical reaction. Sulfur in </span>thiosulfate change oxidation number from +2 to +5 tetrathionate anion (two<span> sulfur </span>atoms in the ion have oxidation state<span> 0 and two atoms have oxidation state +5).</span>
Answer;
Iodine
Explanation;
Electron configurations are a way of keeping track of the location of the electrons around the nucleus.
Iodine is an element which belongs to the halogen family. The halogen group includes fluorine, chlorine, bromine, astatine, and iodine.
A neutral iodine atom would also have 53 electrons. Its ground state electron configuration would be:
1s22s22p63s23p64s23d104p65s24d105p5
Idk if i'm too late but the answer should be A.
Protons= 12, Electrons= 12, neutrons= 12
Answer:
Neutral (Option D)
Explanation:
[H₃O⁺] = [OH⁻] → Neutral solution pH = 7
[H₃O⁺] < [OH⁻] → Alkaline / Basic solution pH > 7
[H₃O⁺] > [OH⁻] → Acidic solution pH < 7
