5. Gold(Au)- Element
6. Sulfur (S)-Element
7. Carbon monoxide (CO).- Compound
8. Silver(Ag). Element
Explanation:
Ammonia is a nutritive inorganic nitrogen compound present in the air, land, water, and living tissues (think pee). It is a colorless and odorless gas. In the gaseous phase, its chemical formula is NH3, and when exposed to water, much of it ionizes to NH4+ (now called ammonium ion).
Gold bars, gold nuggets, gold dust, coins, and accessories are all created of the same atomic nuclei and cannot be broken down further. The atoms in one piece of gold are much like the atoms in some other piece. As a result, gold is classified as an element.
Sulfur (S), also managed to spell sulfur dioxide, is a nonmetals chemical element that originally belonged to the oxygen group of the periodic table (Group 16 [VIa]). It is one of the most reactive elements. Pure sulfur is a fragile, flavorless, scentless, yellow strong that is poor conductor of electricity and highly soluble in water.
Carbon monoxide is a compound called in which the carbon is only connected with one oxygen. It's a poisonous gas that's colorless, scentless, and flavorless.
Silver (Ag), a white lustrous metal prized for its ornament elegance and electrical properties. Silver belongs to Group 11 (Ib) and Period 5 of the chemical elements, and its physical and chemical characteristics are comparable between copper (Period 4) as well as gold (Period 6).
