Thus lime ( calciumoxide) is made by strongly heating calcium carbonate:
2
In modern manufacturing processes, sodium carbonate and calciumoxide are usually added to the base silica.
3
The precipitate of calcium oxalate may be converted into calciumoxide by ignition without previous drying.
4
Hitherto, for the sake of simplicity, the by-product in the preparation of acetylene has been described as calciumoxide or quicklime.
5
As the calciumoxide absorbs moisture from the air, it must (after cooling) be weighed as rapidly as possible.
6
In other words, as the temperature rises, the heat of hydration of calciumoxide diminishes, and calcium hydroxide becomes constantly a less stable material.
7
Limelight, typically used in theaters in the 19th century, is created by directing an oxyhydrogen flame at a cylinder of calciumoxide, or lime.
8
The reaction, in fact, between calciumoxide and water is reversible, and whether those substances combine or dissociate is simply a question of temperature.
9
Only so much lime is used that an acid manganite is formed corresponding to one molecule of calciumoxide to two of manganous oxide.
10
A mixture of barium oxide and calciumoxide weighing 2.2120 grams is transformed into mixed sulphates, weighing 5.023 grams.
11
The calcium in a sample of dolomite weighing 0.9380 gram is precipitated as calcium oxalate and ignited to calciumoxide.
12
How many cubic centimeters of normal KMnO_{4} will be required to determine the calciumoxide volumetrically in a 1 gram sample of the lime?
13
A sample of magnesia limestone has the following composition: Silica, 3.00%; ferric oxide and alumina, 0.20%; calciumoxide, 33.10%; magnesium oxide, 20.70%; carbon dioxide, 43.00%.
14
Calciumoxide only masks the odor of decay.
15
[Note 6: On ignition the calcium oxalate loses carbon dioxide and carbon monoxide, leaving calciumoxide:
