Can chemical changes be reversed?
Yes it can, if you alter the conditions. For instance, if you heat calcium carbonate strongly it will decompose to calcium oxide and water. Limestone is a form of calcium carbonate and we heat it on a large scale to manufacture calcium oxide (quicklime) which is an ingredient of cement, mortar and concrete. CaCO3 à CaO + CO2but when concrete sets,. CaO + CO2à CaCO3 again.
Which is more basic calcium carbonate or calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
When carbon IV oxide is passed into lime water for a long time the product formed is?
calcium carbonate
Why does not wall imidiately acquire white colour when a coating of slaked lime is applied?
As slaked lime is of calcium hydro oxide it takes time. when heat react with calcium hydro oxide the water of calcium get evaporated it become quick lime (calcium carbonate). as the water evaporated the carbon dioxide get a chance to react with calcium carbonate and forms white colour.....

What is the word equation for calcium oxide and water?
In most industrial processes calcium carbonate and water is the product of the combination of calcium hydroxide and carbon dioxide.Calcium hydroxide + carbon dioxide → calcium carbonate + water
Can calcium oxide be used to neutralise water polluted with acid rain?
No, you need Calcium Carbonate not Calcium Oxide to neutralize the acid.
How does the limestone cycle work?
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:

What are the effects of heat on sodium carbonate?
sodium oxide, carbon dioxide and water 2nd answer: there will be no effect on sodium carbonate if it is heated as sodium carbonate will not be decompose upon heating.
Which is more basic calcium carbonate or calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
What is the difference between calcium carbonate and calcium oxide?

Why does not a wall immediately acquire a white colour when a coating of slaked lime is applied on it?

How does molasses react with calcium Oxide?
calcium oxide react with water it forms calcium hydroxide which is available in molasses . when molasses fermented started it leaves Co2 and alcohol. this CO2 react with calcium hydroxide it form calcium carbonate. it become hard material
What is a lime?
a type of citrus fruit and calcium oxide that is greenLime is Calcium Carbonate (usually upto 96% plus other metallic elements) in it's natural form, when you burn it, it becomes calcium oxide, generally speaking for building you then add it to water making calcium hydroxide then it resets back to calcium carbonate... thus the lime cycle.
