41. The industrial method for obtaining beryllium is reduced to the process: BeF2 Mg = Be MgF2. Why can´t beryllium be obtained by reducing beryllium oxide with coal? For a reasoned answer, use the standard values of ΔG0 of the sample:
(∆G°298)o6p. BeO = -582kJ/mol, (ΔG°298) arr. CO2 \u003d -394.38 kJ / mol,
(∆G°298)o6p. BeF2=-941.0kJ/mol, (ΔG°298)o6p. MgF2=-1071 kJ/mol.
