When limestone CaCO3 is roasted quicklime is produced according to equation actual yield of CaO is 2.5 kg when 4.5 kg of limestone is roasted what is percentage yield?
The percentage yield is 100 %.
How is lime mined?
Limestone may be mined in a surface quarry, typically by drilling, blasting, and crushing the shot rock. In some areas, limestone mines are underground. In Florida, some limestone mines are under water- the rock is drilled, shot, and mucked while under water. Limestone may be crushed to aggregate sizes, or finely crushed to a powder state for agricultural limestone, or used a "mine safety dust" to control methane and dust in coal mines. Powdered limestone (calcium carbonate) may be roasted and hydrated to form quicklime (Calcium oxide or calcium hydroxide)

How is oxygen removed from iron ore?
Iron ore is mixed with coke (almost pure carbon from coal) and roasted at high temperatures. The carbon reacts with the oxygen to produce carbon dioxide leaving the elemental iron.

The percentage yield is 100 %.
Is portland cement natural or man made?
It is man made. The basic ingredients are limestone and clay which are roasted in a kiln.
What rock is cement made of?
Limestone is roasted to make lime (calcium oxide) or slaked lime (calcium hydroxide).Other materials and rocks added during roasting are clay, shale, sand, iron ore, bauxite, fly ash, and slag which provide alumino-silicates.

Can Limestone be used for the smell of a decompostion of a dead animal?
Lime (quicklime) is made from limestone- but it is not the same thing. Agricultural lime is powdered limestone. Quicklime is limestone (calcium carbonate) that has been roasted and changed to Calcium Oxide. Slaked quicklime is quicklime that has had water added- Calcium hydroxide. Quicklime is used for odor control.
Why can some people although allergic to peanuts still ingest smooth peanut butter without a reaction?
