What else can I help you with?
What has the larger surface area a lump of chalk or chalk powder?
Chalk powder has a larger surface area compared to a lump of chalk. This is because the process of grinding chalk into powder increases the total surface area exposed to the surrounding environment. As a result, the smaller particles of chalk powder provide more surface area for reactions, interactions, or absorption than a single lump of chalk.
By which process can you separate a mixture of naphthalene and chalk powder?
Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
What is the chemical formula of refractory chalk powder?
CaCO3

Can filter paper separate chalk powder?
No, filter paper is not suitable for separating chalk powder. Chalk powder is insoluble in water, so it will not pass through the filter paper when mixed with water. To separate chalk powder from water, you can use techniques like sedimentation or decantation.
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.
What kind change is grinding chalk into powder?
Grinding chalk really doesn't change the chalk except to make it into powder. So that makes it a physical change. It is much like ice melting into water.

Is chalk powder is soluble in water or not?
