Break an egg carefully and transfer the transparent part of the content to 100 mL of 5% w/V saline solution and stir well

Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the yellow part of the content to 100 mL of 5% w/V saline solution and homogenize with a mechanical shaker

Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the white part of the content to 100 mL of 5% w/V saline solution and homogenize with a mechanical shaker

Break an egg carefully and transfer only the yellow part of the content to 100 mL of 5% w/V saline solution and stir well

At T < 1200 K, oxidation of carbon is unfavourable

Oxidation of carbon is favourable at all temperatures

At T < 1200 K, the reaction $$MO(s) + C(s) \to M(s) + CO(g)$$ is spontaneous

At T > 1200 K, carbon will reduce $$MO_{(s)}$$ to $$M_{(s)}$$.
