Uhm Did u have Questions or pic. So I can Answer your Question
Thanks
There is no energy available to transfer to the surroundings when bonds break as it's an endothermic reaction.
<h3>What is Endothermic reaction?</h3>
This is the type of reaction in which heat is absorbed from the surrounding and is involved in the breaking of bonds.
There is no energy available to transfer to the surroundings when bonds break because it's needed in the conversion of the reactant to product in a chemical reaction.

The average atomic mass of the element rhenium (Re) is 186.208 amu
<h3>Data obtained from the question</h3>
Ffrom the question given above, the following data were obtained:
- Mass of isotope A = 184.955 amu
- Mass of isotope B = 186.956 amu
- Abundance of B = 62.60%
- Abundance of A = 100 - 62.60 = 37.4%
- Average atomic mass =?
<h3>How to determine the average atomic mass </h3>
The average atomic mass of the element can be obtained as illustrated below:
Average atomic mass = [(Mass of A × Abundance of A)/100] + [(Mass of B × Abundance of B)/100]
Average atomic mass = [(184.955 × 37.4)/100] + [(186.956 × 62.60)/100]
Average atomic mass = 186.208 amu
Thus, the average atomic mass of the element is 186.208 amu

You would check to see if there where any wounds on the body look or traces of Poisson in the throat then you could determine if it was because of the fire.
