When two compounds react do they only give off only other compounds or elements as well?
both :P the elements and compounds in the original substances will join together to form a new substance, with possible elements left over i.e. oxygen+glucose --> carbon dioxide+water (respiration)
What is the name for new substances produced in a chemical reaction using two compounds?
A binary compound
What is formed when two substances combine and form a new substances combine and form a new substance which cannot return to their original form?

What is the total of original and new substances that are the same after a chemical change?
