Answer:
D) Mg(s)
Explanation:
We are given:
The substance having highest positive potential will always get reduced and will undergo reduction reaction. Here, chlorine will undergo reduction reaction will get reduced. Magnesium will undergo oxidation reaction and will get oxidized.
<u>Reducing agents are the species which reduces others and oxidizes itself. Thus, Magnesium will be the strongest reducing agent.</u>
Half-life is a time in which the concentration of the substance gets reduced to 50% of the initial concentration. The number of tritium that will be left after 51 years is 0.624 kg.
<h3>What is an isotope?</h3>Isotopes are chemical substances that have the same atomic number but different atomic mass because they have a different number of neutrons in the nuclei.
The half-life of the isotope, tritium is 12.3 years. Assuming we have 11 kg of substance and a number of years 51 years.
Therefore, the number of tritium that will be left after 51 years is 0.624 kg.
