nonpolar
No, chalk is insoluble in kerosene. Chalk is primarily composed of calcium carbonate, which is not soluble in non-polar solvents like kerosene.
Powdered soap does not dissolve in kerosene as kerosene is a non-polar solvent, while soap is made of polar molecules. This difference in polarity prevents the soap from dissolving in kerosene.
Calcium carbonate (chalk) is only sparingly soluble in water. Being ionic, it is even less soluble in non-polar hydrocarbons like petrol.
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.
Toothpaste is typically a mixture of polar and non-polar substances. The surfactants in toothpaste are usually polar, while other ingredients such as thickeners and abrasives can be non-polar.

This is a suspension.
It is usually powdered lime.
Chalk (Powdered CaCO3) may be used for fine polishing.

water and chalk mixed in a bowl
because it consists of small particles that are similar to liquid. Even if we add water to a powdered chalk, it dissolves easily whereas a lump of chalk is harder to dissolve in water.
