What is chalk dust made of?
crushed limestone then it is pressurized so that it for like a solid rock but is not as rigid as a rock because you can write with it on a blackboard.
What is the physical state of marble at room temperature?
Solid.
How fast does vinegar dissolve marble?
This depends on the ratio liquid/solid, type of marble, temperature, pressure, stirring, marble granules dimension, vinegar concentration etc.
When chalk dissolves in water how can it be collected?
Chalk particles can be collected by using a filtration process. A filter paper or a fine sieve can be used to separate the dissolved chalk particles from the water. The water can then be evaporated to obtain the solid chalk residue.
Solid limestone may change into a cave when?
It doesn't! :-)) Caves represent a loss of rock, not a change, by dissolution of the limestone by weakly acid ground-water.
What element is a solid found in marble limestone chalk and teeth?
Calcium.
Which element is a solid found in marble limestone chalk and marble?
CALCIUMThis element is calcium (Ca).
What is CaCO3 at room temperature?
Calcium carbonate is a solid, such as chalk or limestone.

How do you separate salt and marble chips?
First you mix both chalk and salt in water. From the solution that you get, you can filter the chalk out because it is non soluble in water. As for the salt, all there is to do is to just evaporate the water out.
Is marble a solid liquid or gas?
Marbles ARE solid.
Is a marble a solid?
Yes.
A solid that cannot be dissolved in water?
Chalk
What is a marble veneer?
A marble veneer is a thin layer of marble that is attached to a different material, such as plywood or metal, to create the appearance of solid marble. It is commonly used in furniture, countertops, and decorative finishes to achieve the look of marble at a lower cost.
When do we use filtration?
We use filtration when we want to separate a solid and a liquid. e.g. chalk and water The residue left behind at the filter paper will be chalk in this case, for it is a solid:)
What is the white solid produced when heating limestone?
When limestone (CaCO3) is heated, calcium oxide is produced!
What mass of carbon dioxide will be produced?
Full question: Ordinary chalkboard chalk is a solid mixture with limestone (calcium carbonate) and gypsum (calcium sulfate) as its principal ingredients. The limestone dissolves in dilute hydrochloric acid, producing calcium chloride, carbon dioxide, and water. 1.) Gypsum does not react with HCl. If a 5.05g piece of chalk that is 72.0% calcium carbonate is dissolved in excess HCl, what mass of carbon dioxide will be produced? 2.) Determine the mass percent of calcium carbonate in a 4.38g piece of chalk that yields 1.31g carbon dioxide when it reacts with excess HCl?
