Which is an example of a highly unstable isotope that is often used in fission reactions?
a. c-12
b. c-14
c. u-235
d. u-238

C. U-235

Explanation:

A fission reaction is one in which an unstable radioisotope breaks down into smaller nuclei when bombarded with energetic particles.

The highly unstable isotope that is often used in fission reactions is U-235. When bombarded with neutrons that atom breaks down to form krypton and barium along with the release of a large amount of energy. The reaction is given as:

₉₂U²³⁵ +  ₀n¹  →   ₃₆Kr⁸⁹  +  ₅₆Ba¹⁴⁴  + 3₀n¹ + 210 Mev energy

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
