| 11. | On solution with water, the calcium oxide is more soluble.
|
| 12. | This late, disruptive expansion is caused by hydration of large particles of calcium oxide.
|
| 13. | It is based on calcium oxide and used for interior and exterior wall decorations.
|
| 14. | If the reaction is incomplete, excessive amounts of free calcium oxide remain in the clinker.
|
| 15. | Quicklime or Calcium oxide is very nasty stuff, used by the mafia on dead bodies.
|
| 16. | For pH control, popular chemicals include calcium carbonate, calcium oxide, magnesium hydroxide, and sodium bicarbonate.

| 17. | Cement was made of hydrated lime ( calcium oxide ) mixed with sand and water.
|
| 18. | Mining produces calcite, marble, calcium oxide, onyx, and lime.
|
| 19. | It may be produced synthetically by reacting calcium oxide or calcium hydroxide with formic acid.
|
| 20. | Alternatively, calcium carbonate is prepared from calcium oxide.
