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 else can I help you with?
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 does zinc carbonate decompose more readily than calcium carbonate?
Zinc carbonate decomposes more readily than calcium carbonate primarily due to the differences in their thermal stability and lattice energies. Zinc carbonate has a lower decomposition temperature because the bonds in its structure are weaker compared to those in calcium carbonate. Additionally, zinc ions have a smaller ionic radius, leading to less effective packing in the crystal lattice, which contributes to its lower stability. As a result, zinc carbonate breaks down into zinc oxide and carbon dioxide at lower temperatures compared to calcium carbonate.
Which carbonate decomposes the quickest when?
Calcium carbonate (CaCO₃) decomposes more quickly than many other carbonates when heated. This decomposition process produces calcium oxide (CaO) and carbon dioxide (CO₂). Factors such as temperature and the specific form of the carbonate can influence the rate of decomposition, but generally, calcium carbonate is known for its relatively rapid breakdown under heat compared to heavier carbonates like barium or lead carbonates.
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 [:
How does pH affect the solubility of calcium carbonate?
The solubility of calcium carbonate decreases as pH increases. This is because calcium carbonate is more soluble in acidic conditions and less soluble in basic conditions.
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
Is the heating of calcium carbonate a synthesis reaction?
Heating of calcium carbonate (CaCO3) to produce calcium oxide (CaO) and carbon dioxide (CO2) is a decomposition reaction, not a synthesis reaction. This reaction involves breaking down a compound into simpler substances, rather than combining two or more substances to form a new compound.
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

Which is more soluble in water sodium carbonate naphthalene or calcium carbonate?
Sodium carbonate is more soluble in water than calcium carbonate and naphthalene. Sodium carbonate is a water-soluble salt, while calcium carbonate is sparingly soluble in water, and naphthalene is insoluble in water.

Why use calcium lactate and not calcium carbonate or other OTC calcium supplements?
Calcium lactate is more easily absorbed by the body compared to calcium carbonate, making it a more efficient way to supplement calcium. Additionally, calcium lactate has fewer gastrointestinal side effects such as bloating or gas that are commonly associated with calcium carbonate. Overall, calcium lactate may be a better choice for individuals who have difficulty absorbing calcium carbonate or experience digestive issues with traditional OTC calcium supplements.
