14.A common radiotracer used in nuclear medicine SPECT imaging is the 123I isotope. Iodine is very useful in the imaging of the thyroid and decays by electron capture. Write the complete nuclear decay equation. (10 pts)

₅₃I¹²³ + ₋₁e⁰ => ₅₂Te¹²³

Explanation:

Nuclear decay equations require that the mass and charge are conserved. That is, by mass I-123 + e⁻ => Te-123  & by charge ₅₃I + ₋₁e => ₅₂Te. Together, the nuclear decay equation becomes ₅₃I¹²³ + ₋₁e⁰ => ₅₂Te¹²³.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
