Yes- fire is an example of combustion- the reaction with oxygen to produce a variety of products which depend on the material being burnt- burning say coal or oil gives CO2 and CO as well as many other compounds. Yes it is. When you set something on fire, it means you are oxidizing it.

When a wax taper is used to light a firework is it a chemical or physical change?
Phisical re action: when the wax turns to liquid when the liquid cools down it turns to solid which goes back to its own form again soryy i don't know the chemical reaction
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
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
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 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?
Does energy change in a chemical reaction?
yes it does i didnt know that at first but it does
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.
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.

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.
