Write a nuclear equation for the fusion of two h−2 atoms to form he−3 and one neutron.

The nuclear equation that represents the fusion of two H-2 atoms to form He-3 and one neutron is:

Explanation:

In a nuclear reaction the nuclides are represented with the chemical symbol preceded by a superscript that represents the mass number (number of protons plus neutrons) and a subscript that represents the atomic number (number of protons).

H-2 is the isotope of hydrogen with 1 proton and 1 neutron, so it is represented as:

He-3 is the isotope of helium with 2 protons and 1 neuron, so it is represented as:

The neutron is represented as:

With that, you represent the nuclear equation for the fusion of two H-2 atoms to form He-3 and one neutron as follows:

The clue is to check the balance of both mass numbers and atomic numbers:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
