is a chemical reaction and chemical change the same if not what is the difference?
A chemical reaction is a change in which a substance reacts with a different substance usually to create a different substance or compound.
A chemical change is a change in the chemical makeup of a substance usually ending with a different sunstance but the beginning substance doesn't necessarily hev to react with anouther different substance.
Since this is not my area of expertise, I searched Google under the key words "chemical reaction change" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps a little more. Thanks for asking.
A chemical reaction and a chemical change are similar but not exactly the same. Let me explain the difference to you.
A chemical reaction is a process by which one or more substances, called reactants, are converted into different substances, called products. This conversion occurs due to a rearrangement of atoms or ions. During a chemical reaction, bonds between atoms are broken and new bonds are formed to create the products.
On the other hand, a chemical change refers to any change that results in the formation of new substances with new properties. This includes both chemical reactions and other processes, such as changes in state (like melting or boiling), changes in color, or changes in odor.
So, in essence, a chemical reaction is a specific type of chemical change that involves the conversion of reactants into products through the breaking and forming of chemical bonds. All chemical reactions are considered chemical changes, but not all chemical changes necessarily involve a chemical reaction.
To determine if a given process is a chemical reaction or a chemical change, you need to consider whether new substances are formed and if there is a breaking and forming of chemical bonds.
