The discussion centers around whether fusion in stars can be classified as a chemical reaction, exploring the definitions and distinctions between chemical and nuclear reactions. Participants seek clarification on the nature of these processes, particularly in the context of stellar fusion.
Participants generally agree that fusion is a nuclear reaction and not a chemical reaction, but there is some variation in the details and definitions provided. The discussion reflects differing interpretations of what constitutes a chemical reaction versus a nuclear reaction.
Some definitions and distinctions between chemical and nuclear reactions remain unresolved, particularly regarding the implications of Dalton's law in the context of fusion.
I think not. Chemical reaction involves two substances that are chemically combined to form a brand new substance which is different from its original properties while nuclear reaction involves two nuclei colliding with each other at high speed to form a new type of atomic nucleus. (Am I correct?) Just like the Sun, hydrogen fuses with hydrogen to form helium via nuclear fusion.pinochet said:im reading a chemistry text and its says in daltons law chemicals can not change into atoms during a chemical reaction.but if fusion is a chemical reaction then this is wrong beacuse in stars for example hydrogen combine with hydrogen to form helium .i guest i need a little clarification of what a chemical reaction is.
