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"Blackboard and sidewalk chalk were originally made from the sedimentary rock of the same name; a form of soft limestone.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."
What else can I help you with?
Is chalk a pure substance?
Chalk is calcium carbonate - CaCO3. Any chemical compound contain some impurities.
Is mixture of chalk and water is a colloid?

Is chalk a mixture or pure substance?
Chalk is a type of limestone composed primarily of calcium carbonate. In its pure form, chalk is considered a pure substance because it has a uniform and definite chemical composition. However, commercially available chalk may contain impurities or additives, making it a mixture.
Is a chalk a base?

How does the polarity of a substance affect how far it travels up the chalk?
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.
