10 points to FIRST person to answer it right.
Answer:
I might be guessing on some of these, but here goes:
1. c. sulfur
2. c. odor
3. a. H2S
4. d. water
5. d. rhombic
6. a. is an oxidizing agent
7. d. sulfuric
1) sulfur
2)odor-rotten egg smell
3)H2S-hydrosulfuric acid is just another name for hydrogen sulfide
4)water- sulfuric acid is hygroscopic and absorbs moisture from air
5)rhombic- rhombic is the only stable allotrope at room temperature (below 96oC)
6)sulfuric acid is an oxidising agent
7)sulfuric acid
