The isotope tritium has a half-life of 12. 3 y. Assume we have 11 kg of the substance. How much tritium will be left after 51 y?

Mama L [17]

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.

$11 \times 2 ^{\frac{-51}{12.3}} = 0.6239 \;\rm kg$

Therefore, the number of tritium that will be left after 51 years is 0.624 kg.

What is the oxidation of KCL?

Assoli18 [71]

Rules:

1) The oxidation number of a monatomic ion equals the charge of the ion.

2)The oxidation number of a Group 1 element in a compound is +1.

3) The oxidation number of a Group 17 element in a binary compound is -1.

4) The sum of the oxidation numbers of all the atoms in a neutral compound is 0.

KCl is an ionic compound. Consists of K+ ions and Cl- ions.

Oxidation of K= +1 (rules 1 and 2)

Oxidation of Cl= -1 (rules 1 and 3)

Rule 4 also applies- +1 + (-1)= 0- a neutral compound

Hope this helps :)
