continued from before....

the question was
what are three chemical characteristics and ten physical characteristics

so then would i have to say something like
-when iron rusts
or
-sugar burns
or something like that

i was thinking that would just be a chemical reaction not a characteristic

Both sugar and iron in your examples are chemical properties. http://en.wikipedia.org/wiki/Chemical_property
thanks :)
Chemical property becomes evident AFTER a chemical reaction has occured.

For example iron has the potential to rust given the right conditions. This is a chemical property.

That is a chemical property.

While a chemical reaction would be like: Iron rusted.
