When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
Is an indicator's reaction in acids and bases a chemical change?
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.
Ions that do not change in a chemical reaction is?
Spectator ions do not change in a chemical reaction as they appear in the reactants and products in the same ionic form. They do not participate in the reaction and are typically omitted when writing net ionic equations.
If the chemical properties of a substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
Is breaking a lump of chalk to make powder a chemical reaction?
Breaking a lump of chalk into powder is a physical change, not a chemical reaction. The chemical composition of the chalk remains the same before and after breaking it into powder.
What is the word for a chemical change in a substance?
A chemical change is the same as a chemical reaction.
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
A chemical change is also called a chemical reaction?
This is true.
Is a chemical change the same as a chemical reaction?
They are just two different terms that mean the same thing.
Is a chemical change a chemical reaction?
Yes. The two terms mean the same thing. They are synonyms.
How many atoms are in a chemical change?
the same as before the reaction
Can you call a chemical reaction a chemical change?
They are just two different terms that mean the same thing.
Is solubilty the same as a chemical Change?
Solubility is forming of chemical bonds between solute molecules and solvent molecules, hence a chemical reaction.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
Is burns in the presence of oxygen physical or chemical change?
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
