Uranium-236 is .

A. Created by fusion reactions

B. an unstable isotope of uranium

C. created from four hydrogen atoms

D. used in the H-bomb

The correct answer is a.

Uranium-236 is intermediate nuclei created by fusion reactions an unstable isotopes of uranium created from four hydrogen atoms used in the H - bomb .

Following is the reaction involved in above process :

²³⁵U + ¹n = ²³⁶U = ¹⁴⁴Ba + ⁸⁹ Kr + 3¹n + 177 MeV

Here ,

²³⁵U = Fision Material ,

¹n = projectile ,

²³⁶U = Intermediate Nuclei

¹⁴⁴Ba and ⁸⁹ Kr = Fission product

hope it helps !

brainliest plzz :)))

A. Created by fusion reactions

Explanation:

happy to help :)

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

im pretty sure its b
