Both the oxygen and metal could be used in future by settlers on the Moon. Samples returned from the lunar surface confirm that lunar regolith is made up of 40-45% percent oxygen by weight, its single most abundant element.

reacts with metal oxides (indied here as MO, where M is a divalent metal, e.g., calcium, magnesium, or iron) the corresponding carbonate is formed and heat is released according to the following chemical reaction: MO + CO 2 → MCO 3 + heat (1) The amount of
Metals were sodium, potassium, calcium, magnesium, iron, zinc, and copper. In the whole study-group and in participants, plasma metal levels did not differ between cases and controls. In males by contrast, there was moderate evidence that zinc levels trended towards increase in AD [10.8 (10.2-11.5)] µmol/L, mean (± 95% CI; P = 0.021) compared with controls [10.2 (9.6-10.4)].

These quotations apply to Germany; in the United Kingdom the price (1905) varied from 27s. to 30s. per kilogram (12s. to 13s. per lb.). Properties. —A freshly prepared surface of the metal closely reseles zinc in appearance, but on exposure to the air it rapidly tarnishes, becoming yellowish and ultimately grey or white in colour owing to the information of a surface layer of calcium hydrate.
