Look up fission and fusion. Basically, with enough energy you can make anything happen.

in short, no.
sorry misread the question, still no, but yes there are plenty of reversible chemical changes. think of a few by yourself.
True it is no common for most chemical changes to be reversible, but they do exist. In highschool and lower grades they don't tell you this becuase it can be confusing for the younger students. look up rechargable batteries

Certainly not. Most chemical changes are reversible. Usually if you react A and B to form AB, you can also separate AB into A and B. Or react AB with C to form AC or BC.

All chemical reactions are in equilibrium. (The reaction may well heavily favour the products over the reactants). Therefore in principle ALL chemical reactions are reversible.
Please use the spell checker

iam learning about all of this right now i just had my test friday...and my teacher told us that one way to tell a chemical change from a physical change is to see if you can reverse it or not...meaning that chemical changes are not reversable...you cant go back to what you started with...while with physical changes you can...if you need anymore help just tell me cuz iam good with this stuff

no once the properties have changed the general rule is that it cannot change back
especially if it has changed state too
