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.

∙ 14y agoThere are several tests, ranging from a product test (react the sample with acid and then find out what is produced) to a phase test (heat a sample to the midpoint of the melting points of the "suspects" and observe its state).

∙ 13y agoCalcium oxide is CaO. It is usually called as quick lime and is a white coloured substance,
which when added to water produces calcium hydroxide and a lot of heat.
Calcium carbonate is a white coloured solid and has a formula of CaCO3 . It is usually used
as chalk, marble and occurs naturally as limestone.

∙ 14y agoThere are several ways to distinguish calcium carbonate from calcium oxide. For one thing, the melting points of these substances are different. However, an easier way to tell them apart is to add them to water. Calcium oxide will react with the water, forming calcium hydroxide and releasing heat. The calcium carbonate will not react or dissolve to any appreciable extent.

What is the correct name for the compound Ca(HCO3)2?
Calcium oxide
What is thermol decomposition?
Metal carbonates decompose when heated, to form an oxide. For example: Calcium + Oxygen = Calcium carbonate oxide Some carbonates decompose more easily than others, in other words, it happens at a lower tempreture.
How long does it take for calcium hydroxide to degrade back to calcium oxide by absorbing carbon dioxide from the atmosphere?
Calcium hydroxide can absorb carbon dioxide and become calcium carbonate; by heating calcium carbonate is transformed in calcium oxide. The time for these reactions depends on the temperature, pressure, volume of the reactants, amounts of reactants, the physical appearance, sometimes stirring etc. Please read a chemical kinetics book for more details and understanding of the chemistry.
Why use calcium lactate and not calcium carbonate or other OTC calcium supplements?
Calcium lactate is more soluble in water than calcium carbonate, and is therefore more easily absorbed by the digestive system.
Is calcium citrate a better calcium supplement than calcium carbonate?
Calciun Carbonate and Calcium Citrate are different in that, Carbonate is not as easy to absorb as Citrate. Carbonate in not recommended for elderly folks due to a decrease in stomach acids. Citrate in more easily absorbed and can be taken at anytime, with or without food.
What is the correct name for the compound Ca(HCO3)2?
Calcium oxide
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 is the product when calcium is burnt?
Ca + 1/2 O2 => CaO, or quicklime. A more common reaction is the heating of calcium carbonate (limestone or marble) to produce oxygen and quicklime. CaCO3 => CaO +O2
What compound is formed with calcium and oxygen?
i believe my calculations with amnothisewis can card your difficulty with thinking up a scietific answer..... none but electrons!!!!1 Calcuim Carbonate CaCO3 Calcuim Sulphate CaSO4 Calcium Oxide CaO Calcium Fluride CaF2 Calcium Chloride CaCl2 Calcium Bromide CaBr2 Calcium Iodide CaI2 Calcium Cyanide CaCN And plenty more just connect Calcium with any negetive ion you can think off. Remember Calcium has a valance of +2

How do you do a hypothesis for calcium oxide and water?
The more Calcium Oxide you put in , the more the temprature rise in the water.
Which is more soluble in water sodium carbonate naphthalene or calcium carbonate?
Sodium carbonate is more soluble.
What does the powdering of calcium carbonate increase the speed of its reaction with an acid?
Powdered calcium carbonate has much more surface area, therefore allowing the acid to access the calcium carbonate much more quickly.
Why use calcium lactate and not calcium carbonate or other OTC calcium supplements?
Calcium lactate is more soluble in water than calcium carbonate, and is therefore more easily absorbed by the digestive system.
What is more reactive calcium or carbon?
calcium because there is calcium carbonate but not carbon calciumate
What is an igneous rock composed of calcium carbonate?
Carbonatite is an igneous rock composed of more than 50% Calcium Carbonate.
