Yes, in the form of Calcium Sulphate
Sulfur usually has a soft, crumbly texture similar to that of yellow chalk or powder. It is also commonly found in its crystalline form, which can have a smooth, glassy texture.
One common method to separate sulfur and fine chalk is through a process called flotation. This involves adding water and a reagent to the mixture to make one of the materials hydrophobic and the other hydrophilic, allowing them to be separated based on their different properties. Another method is to use a sieve to physically separate the particles based on their size differences.
There are a couple of things that make chalk hard. The calcium in chalk is said to make chalk hard.
Chalk is harder than rubber. Chalk is a form of limestone made of calcium carbonate, which is a relatively hard mineral, whereas rubber is a soft and flexible material typically made from natural or synthetic polymers.
No, natural chalk found in nature is formed from the shells of marine organisms, while chalk used on chalkboards is typically made from gypsum or calcium sulfate. The chalkboard chalk is designed to have a smooth texture and be easily erased from chalkboards.
No, sulfur and chalk are not the same thing. Sulfur is a chemical element known for its distinct yellow color and strong smell, while chalk is a soft, white sedimentary rock composed mainly of calcium carbonate. They have different physical and chemical properties.

Some compound words with "chalk" are chalkboard, chalk dust, chalk line, chalk stick.
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ancient marine organisms.chalk is made up of calcium powder and calcium carbonate."Blackboard and sidewalk chalk were originally made from the sedimentary rock of the same name; a form of soft limestone.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."
Definitely chemical. I can tell because when I do it, it lets off a sulfur smell, indicating that hydrogen sulfide has been released. I've run the same test with other acids and come up with similar results, only the residue left behind after evaporation is different. The hydrogen must be bonding with the sulfur inside the chalk and creating that strong smell (more noticeable if you use a odorless acid). Did you know that pure elemental sulfur is odorless? The true chemical you smell is hydrogen sulfide, not plain sulfur.
A collective noun for chalk is a box of chalk.
your an idiot, no a whitle chalk is not longer than aq blue chalk
The word 'chalk' is a neuter noun, a word for a thing that has no gender.
Water is the solvent and chalk is the solute.
