The time it takes for calcium carbonate to form depends on various factors such as temperature, pressure, and the presence of other compounds. In natural settings, it can take years to thousands of years for significant amounts of calcium carbonate to precipitate. In laboratory conditions, the process can be accelerated by controlling these factors.

How long does calcium carbonate take to thermally decompose?
Calcium carbonate typically decomposes when heated to form calcium oxide and carbon dioxide. This decomposition process usually takes place over a temperature range of 825-900 degrees Celsius and can vary in duration depending on factors like the heating rate and the particle size of the calcium carbonate.
What reactions can take place with calcium carbonate and limeatone?
When calcium carbonate reacts with an acid, it produces carbon dioxide gas, water, and a calcium salt. When calcium carbonate reacts with heat, it decomposes into calcium oxide (quicklime) and carbon dioxide gas. Lime stone, which is primarily composed of calcium carbonate, can undergo similar reactions.
What is the common name for calcium carbonate?
The common name of Calcium carbonate may be Chalk, but chemically that's not true, if it is the blackboard writing chalk. This chalk is actually Calcium sulfate, which is mistaken as Calcium carbonate, as its manufacturing process uses Calcium carbonate.So, I think the common name for chalk should be Limestone, which is the most common mineral form of this compound.
What is calcium carbonite?
There is no such thing as calcium carbonite. It is likely a typo or a misspelling. However, calcium carbonate is a common compound found in rocks, shells, and pearls, and is often used as a dietary supplement for calcium.
How many tums tablets each 250mg calcium carbonate would it take to neutralize a quart a vinegar 0.83MM acetic acid?
To neutralize acetic acid, you need a 1:1 molar ratio of calcium carbonate to acetic acid. The molar mass of acetic acid is 60.05 g/mol, so 0.83 mmol is 0.83 * 10^-3 mol. This requires 0.83 * 10^-3 mol of calcium carbonate, which is 0.83 * 10^-3 mol * 1000 mg/mol = 0.83 mg of calcium carbonate. In 250 mg tablets, you would need 0.83 mg / 250 mg = 0.00332 tablets, so you would need at least 1 tablet to neutralize the acetic acid in the quart of vinegar.

Why do you get gas when you take calcium?
Calcium usually exists as calcium carbonate in pill form and when this compound reacts with the acids in your stomach, carbon dioxide is released. That CO2 is your gas.
Where can calcium get nutrients from?
Calcium is a chemical element, you typically take it in the form of the salt Calcium Carbonate. It is not a vitamin. It is typically referred to as a mineral.

Is it harmful to take calcium carbonate with lemon juice?
safe

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.
Benthos that create a hard calcium?
Corals/coral reefs are benthos that build up layers of calcium that take a long time to form.
Will Sodium Carbonate react with Calcium Acetate?
Sodium and Calcium are both highly reactive elements but I do not believe they will react together, as they both have similar reaction properties. Dont take my word for it though as I am a bit rusty on my periodic table. Check the table. The group they each fall into and their chemical numbers will tell you whether or not they will react together. The Carbon in the Sodium Carbonate may act as a catalyst or may prevent any reaction alltogether, as it is not directly reactive to Calcium.
How long does it take for shells to degrade?
Shells are made of calcium carbonate, which can take hundreds to thousands of years to break down completely in the environment. Factors such as water acidity, temperature, and microbial activity can influence the degradation rate of shells.
Is it safe to take expired calcium supplements..They expired in March of 09?
I would say it is probably not unsafe to take them, in fact, I highly doubt that Calcium would ever go bad (Calcium Carbonate is basically chalk). According to FDA standards, the expiration date is the point at which 90% of the medication still remains- meaning if anything, it will be less effective than it would have been.But really, some new calcium supplements should cost $2.00- just take generic tums (Calcium Carbonate). Look for them in the antacid section!
How do stalagmites fom?
They are deposits of calcium carbonate formed on the floor of a cave by the dripping of calcareous water. Can take thousands of years to 'grow'
