What else can I help you with?
Chalk reacts with hydrochloric acid when mixed Will pounding the chalk into powder increase the rate of reaction?
Yes, pounding chalk into powder will increase the rate of reaction with hydrochloric acid. This is because crushing the chalk into a powder increases its surface area, allowing more of it to come into contact with the hydrochloric acid and react.
Is making chalk dust a chemical change?
No, it is a physical, not chemical change.
Chemical reaction of chalk and sodium carbonate?
When chalk (calcium carbonate) reacts with sodium carbonate, a double displacement reaction occurs. The products of this reaction are calcium carbonate and sodium carbonate. The balanced chemical equation for this reaction is: CaCO3 + Na2CO3 → CaCO3 + Na2CO3
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.
Why is breaking chalk a physical change?
Besides for rearranging the glass pieces, one is not actually changing the chemical formula of the glass. Much like grinding NaCl, the crystals get smaller but the chemical remains the same.

How does chalk change after it has been shaken?
After a piece of chalk is pounded by a fist or rolling pin or other object it normally get crushed and turns into lumpy powder.
What is the chemical formula of refractory chalk powder?
CaCO3
Is making chalk dust a chemical change?
No, it is a physical, not chemical change.
Does vinegar and chalk create a chemical reaction?
Yes the chalk is turned into salt and water if there is enough vinegar

What has more friction polished wood or chalk powder or marble?
Chalk powder

Chemical name of precipitated chalk?
The chemical name of precipitated chalk is calcium carbonate. It is a white, odorless powder that is commonly used in industries such as pharmaceuticals, food production, and in the manufacture of paper and plastics.
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.
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.
