How many molecules in formula 2CaCO3?
In the formula 2CaCO3, there are 2 molecules of calcium carbonate (CaCO3) in total. Each molecule of calcium carbonate consists of one calcium atom, one carbon atom, and three oxygen atoms.
Is calcium carbonate a solute?
Calcium carbonate weakly dissolves in water.
What elements make up calcium hydrogen carbonate?
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
How calcium carbonate solve in water?
Calcium carbonate dissolves in water through a process called dissociation. When calcium carbonate is added to water, it breaks down into calcium ions (Ca^2+) and carbonate ions (CO3^2-). These ions then interact with water molecules, causing the calcium carbonate to dissolve.
How many moles are in 8.23 x 1024 of calcium carbonate?
To find the number of moles in 8.23 x 10^24 molecules of calcium carbonate, you first need to determine the molar amount of molecules in one mole of calcium carbonate by using Avogadro's number. Then, divide the given number of molecules by the molar amount to calculate the number of moles.
The total number of protons in 10gm calcium carbonate?
The total number of protons in 10g of calcium carbonate can be calculated by finding the number of moles of calcium carbonate in 10g, then multiplying this by Avogadro's number to get the total number of molecules. Each CaCO3 molecule contains one calcium atom, which has 20 protons. Therefore, the total number of protons in 10g of calcium carbonate can be determined by multiplying the number of molecules by 20.
Is the carbonate or the calcium the buffer in calcium carbonate?
The carbonate. Calcium is neutral.
How much citric acid and calcium carbonate make calcium citrate?
To make calcium citrate, you would typically combine one molecule of citric acid with two molecules of calcium carbonate. So, for every 1 molecule of citric acid, you would need 2 molecules of calcium carbonate to produce calcium citrate.
Is solid calcium carbonate with water an endothermic or exothermic reaction?
The reaction of solid calcium carbonate (CaCO3) with water is an endothermic process because it requires energy input to break the bonds between the calcium, carbon, and oxygen atoms in the calcium carbonate molecule and form new bonds with the water molecules.
What would be the total number of atoms in ten molecules of calcium carbonate?
This number is 50 atoms.
Are seashells made out of carbon?
Seashells are primarily made of calcium carbonate, which is a compound derived from calcium and carbon dioxide. Carbon is a component of the calcium carbonate molecules that make up the structure of seashells, but seashells are not made solely of carbon.
How many molecules of calcium carbonate are present in its one mole?
If its at STP (standard temperature & pressure) then i think 6 x 10^23 molecules
