No. Chalk is calcium carbonate and is insoluble in water. It is an ionic solid with a giant lattice structure.
Traditional blackboard chalk was made from naturally occurring calcium carbonate formed from the remains of minute protozoa. This gave the material a soft quality. Crystalline calcium carbonate, calcite, is a transparent crystalline substance. (Modern blackboard chalks were made from powdered calcium sulfate which is also insoluble in water)

∙ 12y agoMany biomolecules, such as proteins, carbohydrates, and lipids are broken down into their smaller components by a process called hydrolysis, which means "water splitting." In hydrolysis, biomolecules break down by the addition of water molecules.
Refer to the related link for an example of the hydrolysis of sucrose (table sugar).

Why does a piece of chalk called a matter?
A piece of chalk is matter because it has mass and occupies space, which is the definition of matter.

What a piece of calcite is used to write or draw on blackboards?
It is chalk.
Why is a piece of chalk classified as matter?
It has mass and volume, the characteristics of matter.
Why does surface of a reactant influence the rate of the reaction?
A chemical reaction is nothing but the conversion of the reactant molecules into product molecules. By increasing the surface area of the reactants more number of reactant molecules are exposed which eventually increases the rate of the reaction...for example, powdered chalk piece dissolves faster in water than a piece of chalk.

Why does a piece of chalk wear out as it is used on a blackboard?
With every stroke of the chalk piece it leaves some of the chalk on the board. This abrasion of the piece of chalk causes it to wear down. This is similar to why the rubber tyres of cars wear down when they are driven over a road surface.
How do you know if chalk contains calcium carbonate?
Through chemical analysis of a piece of chalk!
