Is crushing a piece of chalk a chemical change or a physical change?
Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.
What do you get when you crush a piece of chalk?
When you crush a piece of chalk you get lots of small pieces of chalk.It is only a physical change. It is not a chemical change.
What happened when the piece of chalk was broken into pieces what there a change?
When a piece of chalk is broken into pieces, there is a physical change as the chalk is simply being divided into smaller fragments. The chemical composition of the chalk remains the same even though it is now in multiple pieces.
When pounding chalk to small bits a physical change or a chemical change?
It's a physical change because it's only changing size and shape, not converting chemicals.
What mixture does mixing vinegar with crushed chalk make?
When vinegar is mixed with crushed chalk (which is mainly calcium carbonate), a chemical reaction occurs. The vinegar (acetic acid) reacts with the calcium carbonate to produce carbon dioxide gas, water, and calcium acetate. This reaction is often used as a fun science experiment to demonstrate the formation of bubbles as carbon dioxide gas is released.

Is a chalk grinding a physical change?
It doesn't matter if something is reversible or irreversible. it will not depend if it is a chemical or physical change. A physical change is when the composition of a substance remains unaltered (the particles stay the same) and no new substance is produced. Such as when you make a paper plane out of paper, the appearance changed, the particles stayed the same, no new substance was created, and the paper remains paper. A chemical change is when the composition of a substance is altered and a new substance is produced. Such as when paper is burned, the new substance produced is the carbon and other gases from the fire, and the composition of the paper changes, slowly disappearing.It usually is unless you draw so rapidly that the heat of the friction heats the paper and causes it to smoke.
Why is a piece of chalk classified as matter?
A piece of chalk is classified as matter because it has mass and occupies space. Matter is anything that has mass and volume, and chalk meets these criteria as it has physical properties and can be measured.
tearing a piece of paper in half physical or chemical change?
Physical change
Why does a piece of chalk called a matter?
A piece of chalk is called matter because it is made up of atoms and molecules, which are the building blocks of all matter in the universe. In this case, the chalk is composed of materials such as calcium carbonate and other compounds that give it its physical properties.

When sandpaper smooths a piece of wood what kind of change is it?
this is a physical change
Is cutting a piece of wood a physical change or a chemical change?
Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.
