Dr. Garcia is a geologist from Peru, and Dr. Ferreira is a geologist from Brazil. They are comparing rocks from their areas for their research and have some information about them. The information is
as follows:
• Rock A formed from small pieces of rock.
• Rock B formed from liquid rock in a different place.
• Rocks A and B formed at about the same time.
As they work on their study, they need to answer the question: Are Rocks A and B the same or
different types of rock?
The rocks are

The given information gives us the clue that deuterium and tritium react together. We need to find the balanced nuclear reaction of deuterium and tritium; however, first, let me explain you what deuterium and tritium are.

Deuterium and tritium are two isotopes of hydrogen having atomic mass of 2 and 3 respectively. Deuterium is represented by , whereas tritium is written as .

When deuterium and tritium collide together, they form Helium atom, which is written as , and also release energy (and shoot out one neutron).

Hence, the balanced nuclear reaction will be the following:

-i
