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?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
What is the correct balanced chemical equation for this reaction?
To provide the balanced chemical equation, I would need to know the specific reaction you are referring to. Can you please provide the reactants and products involved in the 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."
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.
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).
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.
