Question 10 (1 point) Which substance can not be broken down by chemical means? a ammonium chloride -NH 4 Cl b aluminum oxide - Al2O3 c ammonia - NH3 d aluminum - Al

Aluminum, represented by the symbol Al, is a simple element. Unlike compounds like ammonium chloride, aluminum oxide, or ammonia, aluminum cannot be broken down into simpler substances through chemical means because it is already in its most basic form as an element. Elements are the fundamental building blocks of matter, and they stand proud and indivisible, just like the metallic symbol of strength it represents! In practical terms, aluminum is a workhorse in industries ranging from construction to packaging. It's lightweight yet strong, making it the star of manufacturing for things like airplane parts and beverage cans. So next time you pop open a soda, give a nod to aluminum, the unyielding element that made your drink possible!
