Determain the molecular mass of t2 ^17o2. explain answer to me because i have a lot of questions like this

The question deals with isotopes and how their masses differ from their normal elemental counterparts.

Here, T represents tritium, which is an isotope of hydrogen with a mass of 3 amu. Similarly, the isotope of oxygen present is ¹⁷O, which means it has a mass of 17 amu.

To determine the mass of this molecule, we do the following calculation:

3 * 2 + 17 * 2
6 + 34 
40

The mass of T₂¹⁷O₂ is 40 amu

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
