What is the chemical formula of chalk?
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
What is the production of a gas when acid is added to a sample of chalk is an indication?
The production of a gas when acid is added to chalk indicates that the chalk contains calcium carbonate. The acid reacts with the calcium carbonate to produce carbon dioxide gas, which can be observed as bubbles. This chemical reaction is a classic test for the presence of carbonate ions.
What is the chemical symbol for chalk?
The chemical symbol for chalk is CaCO3, which represents the compound calcium carbonate.
When you hydrochloric acid and chalk together is it physical or chemical change?
When you mix hydrochloric acid with chalk, a chemical change occurs. This is because the acid reacts with the calcium carbonate in the chalk to form carbon dioxide gas, water, and calcium chloride. This is a chemical reaction that results in the formation of new substances.
What is the chemical formula for chalk calcium and carbonate?
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula

Is it reversible when vinegar is spotted onto chalk or limestone?
When vinegar is spotted onto chalk or limestone, it creates a chemical reaction that dissolves the calcium carbonate in the rock. This reaction is not reversible as it breaks down the structure of the rock and changes it permanently.
What is the chemical name offor chalk?
CaCO3 ... Calcium Carbonate
What happens when you put chalk in a container of cola?
When you put chalk in a container of cola, a chemical reaction occurs between the calcium carbonate in the chalk and the phosphoric acid in the cola. This reaction produces carbon dioxide gas, which creates bubbles and causes the chalk to fizz and dissolve. The chalk will eventually break down and disappear as it reacts with the acidic cola.
