Explain why noble gases are so called and their general characteristics. Outline the steps to produce Boron.

Assumption: The reactant $\text{NaCl}$ is assumed to be a typo and should be $\text{H}_2\text{SO}_4$ (sulfuric acid) to produce boric acid, which is the starting material for the next step.

The products are boric acid ($\text{H}_3\text{BO}_3$), sodium sulfate ($\text{Na}_2\text{SO}_4$), and water ($\text{H}_2\text{O}$).

Boric acid dehydrates upon strong heating to form boron trioxide.

The products are boron trioxide ($\text{B}_2\text{O}_3$) and water ($\text{H}_2\text{O}$).

Boron trioxide is reduced by magnesium to produce elemental boron.

The products are elemental boron ($\text{B}$) and magnesium oxide ($\text{MgO}$).
