What does sulfur's texture feel like?
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.
How do you separate sulfur and fine chalk?
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.
What is the hardness of chalk?
Chalk has a Mohs hardness of 1, meaning it is very soft and can be easily scratched with a fingernail.
Is chalk harder than rubber?
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.
Is the chalk you find in nature the same as the chalk that you use on the board?
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.
Is sulfur the same thing as chalk?
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.

Which substance is chalk made of?
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ancient marine organisms.chalk is made up of calcium powder and calcium carbonate."Blackboard and sidewalk chalk were originally made from the sedimentary rock of the same name; a form of soft limestone.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."
Is mixing crushed chalk with water a chemical or physical change?
Mixing crushed chalk with water is a physical change. This is because the chalk particles are simply dispersed throughout the water, but no new substances are formed. The mixture can be easily separated back into its original components of chalk and water.
What is a collective noun for chalk?
