Oil or Air? How to store Elemental Calcium metal …

2012-9-25 · As an amateur element collector I have been given a few grams of elemental Calcium metal turnings. I know Ca is not as reactive as the Alkali metals so was hoping to store them in air, within a tightly closed small glass lidded container? Or is it common practice to store Ca under mineral oil? Advice would be very welcome. Many thanks, BF

How many grams of calcium oxide CaO can be …

How many grams of calcium oxide, CaO, can be produced from 4.20 g of calcium metal and 1.60 g of oxygen gas? A) 2.94 B) 2.80 0.5 m C) 5.61 2 m D) 5.88 0.5 m E) 5.80 The balanced reaction is: Ca + ½ O 2 CaO 1.6 g O 2 (g) = 0.05 mole O 2 and 4.20 g Ca = 0.105 mole Ca. Hence O 2 is the limiting reagent. 0.05 mole O 2 yields 0.1 mole CaO = 5.61 g.
