Since limestone is predominantly composed of calcium carbonate (CaCO3), it is soluble in acid (or when crushed soluble in water) and is an alkali. Also it makes good lime for the garden, when heated properly it makes good portland for concrete, and is used in toothpaste and antacids.
For information on the material properties of limestone, such as strength, stiffness and density, please see the related questions.

What is the kindof the change represented by grinding chalk into a powder?
A physical change.
Do you use chalk?
No, I am a digital assistant and do not use physical writing tools like chalk.
What is an organism's physical appearance called by genetics?
False. An organisms physical appearance is its phenotype.
Is chalk made of skeliton?
Chalk is not made of skeletons. It is primarily composed of calcium carbonate, which is a mineral that is found in rocks such as limestone and marble. When chalk is used for writing on chalkboards, the dust particles that are released can sometimes give the appearance of being similar to bone dust, but chalk itself is not made of skeletons.
Is CHALK a foliated rock?
No, chalk is not a foliated rock; it is classified as a sedimentary rock. Chalk is composed predominantly of calcite and formed from the accumulation of tiny marine organisms' remains. Foliated rocks, such as schist or gneiss, have a layered or banded appearance due to the alignment of minerals under pressure, which does not occur in chalk.
Is crushing a piece of chalk a chemical change or a physical change?
Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.
Is a piece of chalk crushed a physical change?
Yes, crushing a piece of chalk is a physical change because the chalk is still composed of the same molecules before and after being crushed. The change in appearance is only due to the physical state of the substance.
What is the kindof the change represented by grinding chalk into a powder?
A physical change.
When chalk is crushed is it a physical or chemical property?
Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.
Is pulverized chalk a physical or chemical change?
Grinding chalk to chalk dust is a physical change because the texture and size may change but the its molecules are still the same.An example of chemical change is burning paper because ash is chemically different from paper.
When pounding chalk to small bits a physical change or a chemical change?
It's a physical change because it's only changing size and shape, not converting chemicals.
Is a chalk grinding a physical change?
It doesn't matter if something is reversible or irreversible. it will not depend if it is a chemical or physical change. A physical change is when the composition of a substance remains unaltered (the particles stay the same) and no new substance is produced. Such as when you make a paper plane out of paper, the appearance changed, the particles stayed the same, no new substance was created, and the paper remains paper. A chemical change is when the composition of a substance is altered and a new substance is produced. Such as when paper is burned, the new substance produced is the carbon and other gases from the fire, and the composition of the paper changes, slowly disappearing.It usually is unless you draw so rapidly that the heat of the friction heats the paper and causes it to smoke.
What kind change is grinding chalk into powder?
Grinding chalk really doesn't change the chalk except to make it into powder. So that makes it a physical change. It is much like ice melting into water.
Do you use chalk?
No, I am a digital assistant and do not use physical writing tools like chalk.
Is mixing chalk with water a physical change or chemical change?
physical :)
If chalk doesn't dissolve in water is it a chemical or physical change?
It is a physical change because the chalk is still chemically the same substance whether it is in solid form or dispersed in water. The molecules in the chalk are not altered by the process of being put in water.
Is breaking a lump of chalk to make powder a chemical reaction?
Breaking a lump of chalk into powder is a physical change, not a chemical reaction. The chemical composition of the chalk remains the same before and after breaking it into powder.
