Evidence of a chemical reaction include the following:
formation of a precipitate
formation of a gas
change in temperature
change in color
Burning is a chemical reaction, an oxydation.
No. A chemical reaction is not alive.
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).
A chemical reaction is represented by a chemical equation.
A chemical reaction is a process that changes one or more substances into new substances with different chemical properties. This involves the breaking and formation of chemical bonds between atoms or molecules.
don't know

Chemical change. References: Intro to Matter book.
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?
yes it does i didnt know that at first but it does
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.
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.
Chemical reaction
Combustion is a chemical reaction.
No. A chemical reaction is not alive.
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.
