August 2018 NY Regents Chemistry
8 Which substance can be broken down by chemical means?
(2) aluminum (3) antimony
Solution: Elements can not be broken down by a chemical change. Compounds can be broken down by chemical means. We can eliminate all the choices that have elements to arrive at the correct answer. The names of all of the elements can be found in Table S on the Reference Table. Out of all the choices, ammonia is the only compound.
