What occurs in a lime kiln?
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is:CaCO3 + heat → CaO + CO2 This reaction takes place at 900°C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000°C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.
How do you know that the air breathed out contains carbon dioxide gas?
You can test it with the Lime Water test. If there is carbon dioxide in your breath then the Lime Water should turn cloudy.
Why is hot air blown into lime kiln?
so that limestone can decompose to form CO2 and CaO
Spurite ring formation in cement kiln?
carbonate or spurite ring are form through CO2 resorption into the freshing formed free lime or even through belite recorbonation in the kiln. these rings are harder and exibit the same chemistry as regular clinker, the presence of spurite a minral with composition CA2SO4 CACO3, When the carbonate in the spurite is replaced with sulfer, the new material is called sulfated spurite. Spurite ring basicaly form when ever the partial press of CO2 above the bed of material is high enough to invert the calcining reaction increase the ground silica rich rawmixes and free lime does not have sufficient lime in the calcining zone to react with silica therefore increasing the chances for spurite deposit in the kiln.

What is a greek painting in wet plaster called?
Fresco. Any in plaster, not just Greek.In it's essence, fresco or fresco painting is an - application of natural mineral pigments to a surface on which a following chemical reaction takes place:Ca(OH)2(s) + CO2(g) ----> CaCO3(s) + H2O(l)Calcium Hydrate (burned lime stone or marble mixed with water) combined with carbon dioxide resulting in the formation of Calcium Carbonate - lime stone, marble. The pigment gets trapped within the newly formed calcite crystal. It is like "Painting with molten Marble".
Why is carbon dioxide created in a lime kiln?
Calcium Carbonate is decomposed into Calcium Oxide and Carbon Dioxide when massive amount of heat is provided.
What is the word equation for the endothermic reaction which occurs in lime kiln?
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
When methane is burned in a lime kiln why are the wast gages carbon dioxide and nitrogen?
the oxygen in the air combines with the methane making carbon dioxide and leaving un reacted nitrogen from the air.
What happened to the carbon dioxide the animals produced while in the chamber?
The carbon dioxide was absorbed by the soda lime in the bottom of the chamber.
Purpose of lime water with marble chip?
Lime water is used in an experiment to test if carbon dioxide is produced from acid reacting with a marble chip. If you see a calcium carbonate in your lime water at the end of the reaction, you will know that it produced the gas, carbon dioxide.
Lime water goes cloudy when reacted with carbon dioxide which substance is produced?
calcium carbonate
What substance is produced when lime water goes cloudy?
Add carbon dioxide to it. The carbon dioxide will react to form a precipitate which makes the water appear cloudy.
Give two reactions which produce carbon dioxide in the lime kiln?
One reaction is calcium carbonate is calcium oxide plus carbon dioxide. Another reaction is carbon plus oxygen which equals carbon dioxide.
What happens when acid react with compounds made of carbonate?
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!

What reacts with lime water forming a precipitate?
Carbon dioxide
What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
