[edit]

I would like a citation added for this section "It is also customary and considered lucky in Scotland and the North of England to give coal as a gift on New Year's Day. This occurs as part of first-footing and represents warmth for the year to come."

I see no proof of this online. Magus2758 (talk) 10:01, 21 November 2024 (UTC)Reply

President Trump's reclassification

[edit]

Lignite versus brown coal.

[edit]

Under “Composition” you distinguish between lignite and brown coal in terms of the percentage of carbon in its composition. Under “Types” you treat lignite and brown coal as synonymous. Which is true? StephenHCS. ~2026-48364-1 (talk) 18:00, 3 April 2026 (UTC)Reply

Unconventional notation.

[edit]

Under “Coke” you have: 2 Fe2O3 + 6 CO → 4 Fe + 6 CO2 So why not simply write: Fe2O3 + 3 CO → 2 Fe + 3 CO2 StephenHCS. ~2026-48364-1 (talk) 18:16, 3 April 2026 (UTC)Reply
