In a hydrogen fusion reaction two lighter hydrogen nuclei merge to form a heavier more stable helium nucleus. the energy that is released in a hydrogen fusion reaction is

is very large and it provides the needed temperature for another set of fusion

Explanation:

Nuclear fusion is the combination of two atomic nuclei into larger ones.

One of such is used in making hydrogen bonds.

In nuclei fusion,

²₁ H + ²₁ H → ⁴₂He + energy

This is an example of nuclear fusion.

The energy helps to further the fusion process and a chain reaction occurs and a massive amount of energy is released.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
