No, it is a chemical change.
sawdust pilling under the table.
No. Antacids neutralize the hydrochloric acid in the stomach. It is a chemical change.
This change is a physical change because the matter is made up of the same components that it consisted of before it was broken. An example of a chemical change is the molecular rearrangement of matter like rust on a car.
Sawdust is not a change. Making solid wood into sawdust by sawing it, would be a physical change.
Because the antacid neutralizes the the HCl in the stomach (or at least in excess amount) to produce water and a salt, and it is good example of neutralization reaction.
Is an example of chemical change, reacting to air
crushing a sugar cube is a physical change
a substance that can neutralize the acid by reacting with hydrogen ions.
Its A physical change. When you boil water under a stove, The water evaporates and the chemical stays in the..pan or whatever you put in it.
An example: 2HCl + Mg(OH)2 = MgCl2 + 2H2O
forces between chemical reactions for example ethene reacting with hydrogen gas
