Primarily calcium carbonate, derived from the skeletons of very small ancient marine organisms.
chalk is made up of calcium powder and calcium carbonate.
"Blackboard and sidewalk chalk were originally made from the sedimentary rock of the same name; a form of soft limestone. Chalk, composed principally of calcium carbonate (CaCO3), formed underwater by slow accumulation and compression of the calcite shells of single-celledcoccolithophores."
Chalk is calcium carbonate - CaCO3. Any chemical compound contain some impurities.
No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
No, chalk is not a base. Chalk is a form of limestone composed mainly of calcium carbonate, which is a basic substance.
The polarity of a substance affects how strongly it interacts with the chalk. More polar substances will travel up the chalk further because they can form stronger interactions with the polar sites on the chalk surface through processes like capillary action. Less polar substances will travel up the chalk less because they have weaker interactions with the chalk.
When you crush chalk, the solid structure of the chalk breaks down into smaller particles. This results in a powder-like substance that is easier to spread and work with.
The chalk-like substance is, in fact, chalk.
Chalk is calcium carbonate - CaCO3. Any chemical compound contain some impurities.
Sidewalk chalk is made up on calcium carbonate, which is a mild alkaline substance (a base). Acids corrode metals, bases do not. Therefore, sidewalk chalk should not rust metal.

Chalk powder is a fine powder made from crushing and grinding natural chalk into a soft, white substance. It is commonly used in various applications, such as in classrooms for writing on chalkboards, in sports for marking playing fields, and in recreational activities like rock climbing.

No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
No, chalk does not contain sulfur. Chalk is primarily composed of calcium carbonate, a mineral substance that does not contain sulfur.
