The equation B + 2F3H -> BF3 + 3H2

The above chemical equation illustrates the chemical reaction process between boron (B) and hexafluoride (F₃H) to create boron trifluoride (BF₃) and hydrogen (H₂). The equation is balanced, that is, the number of atoms of each element on the left and right sides of the equation are equal.

Reaction conditions: Most chemical reactions require appropriate temperature and pressure to occur. However, the specific conditions for this reaction are not clearly mentioned. Also note that F₃H is not the exact formula of the chemical compound, so it may need to be reviewed or clarified.

Reaction process: During the reaction process, boron atoms will combine with fluorine atoms to form boron trifluoride, while hydrogen from hexafluoride will separate to create hydrogen.

Occurring phenomena: The specific phenomena during the reaction process will depend on many factors such as reaction conditions, concentration of participating substances, etc. However, typically, you may observe changes in color, temperature, pressure or even the emission of light or sound.
