31. Basic gases ( e . g . ammonia ) can be dried with calcium oxide , sodium hydroxide or soda lime. 32. Sodium silicate glass is a silicate glass, which contains alkali-and alkaline earth oxide and primarily sodium oxide and Calcium oxide . 33. Owing to the high concentration of calcium oxide in fly ash, the bricks can be described as " self-cementing ". 34. In this type of illumination, a gas flame is used to heat a cylinder of quicklime ( calcium oxide ). 35. Calcium carbonate ( limestone ) is decomposed by heat to produce Calcium oxide ( quicklime ) and carbon dioxide gas. 36. Industry is limited to a water purification facility, an ice plant and one that processes calcium oxide ( calidra ). 37. So then what does the electronic structure of compounds like zinc oxide, magnesium oxide, calcium oxide , strontium oxide actually look like? 38. The origin is absolutely literal : Limelights were stage lights in which lime ( calcium oxide ) was heated to incandescence. 39. A supposedly more stable mixture of calcium hypochlorite and quicklime ( calcium oxide ) is known as " tropical bleach ". 40. Even though the product is contaminated and smelly it may be purified by addition of calcium oxide and subsequent fractional distillation.
