What is the chemical symbol for chalk?
The chemical symbol for chalk is CaCO3, which represents the compound calcium carbonate.
Is making chalk dust a chemical change?
No, it is a physical, not chemical change.
What is the chemical formula of chalk?
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
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.
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 it possible to distinguish chalk from kaolin without using acid explain?
Yes, it is possible to distinguish chalk from kaolin without using acid. One way is to conduct a streak test - kaolin will have a white streak while chalk will not. Additionally, kaolin has a greasy feel when touched, unlike chalk which feels powdery. Lastly, kaolin is less friable and harder than chalk, so their physical properties can also help differentiate them.
How do you know if chalk contains calcium carbonate?
You can test if chalk contains calcium carbonate by placing a small amount of vinegar or another acid on the chalk. If it bubbles or fizzes, it indicates the presence of calcium carbonate, as it reacts with the acid to produce carbon dioxide gas. Additionally, you can perform a simple acid-base titration to confirm the presence of calcium carbonate in the chalk.
Chemical name for chalk?
Calcium carbonate
Is chalk clastic chemical or organic?
It is clastic
How do you separate chalk water?
Due to the chemical composition of Chalk, you can separate it from water either by filtration of evaporation.
Does vinegar and chalk create a chemical reaction?
Yes the chalk is turned into salt and water if there is enough vinegar
When you hydrochloric acid and chalk together is it physical or chemical change?
When you mix hydrochloric acid with chalk, a chemical change occurs. This is because the acid reacts with the calcium carbonate in the chalk to form carbon dioxide gas, water, and calcium chloride. This is a chemical reaction that results in the formation of new substances.
