Is picking up iron filings with a magnet a chemical reaction?
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
A change in matter that produces new substances is called?
Chemical change. References: Intro to Matter book.
How can you know this is a chemical reaction?

What sentence has the word chemical reaction?
A chemical change is a resultant change of a combination of a couple different substances that become a new substance. A sentence with this is: "Its particles changed due to it undergoing a chemical change."
Why do you have to balance chemical equations?
You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).You only need to balance a chemical equation if you want to know the proportions (how many of each type of molecules participate in the reaction).
When hydrochloric acid is mixed with calcium is that a chemical or a physical reaction?
The reaction between hydrochloric acid and calcium is a chemical reaction because new substances are formed. In this reaction, calcium displaces hydrogen from hydrochloric acid to produce calcium chloride and hydrogen gas. This process involves a rearrangement of atoms and the formation of different chemical bonds.
What states that volume is neither created nor destroyed in chemical reaction?
As far as I know this is not true- volume can be increased or decreased. What is conserved in a chemical reaction is mass. Matter is not created or destroyed.
How does the motion of molecules affect a chemical reaction?
the answer is unknown the world may never know.
