Question 2 Which equation depicts aqueous hydrogen sulfide behaving as a Brønsted-Lowry acid in water? a. H₂S(aq) + 2 OH (aq) →→→ SO₂(aq) + 2 H₂(g) b. H₂S(aq) + H3O*(aq) →→→ H3S*(aq) + H₂O() c. H,S(aq) + H2O(0) + +HS (aq) + H3O*(aq) d. HS (aq) + H₂O*(aq) →→→→H₂S(aq) + H₂O() e. H₂S(aq) + H₂O(l) <→→→→ H3S**(aq) + OH (aq) a b

During the experiment, can the crucible and lid be touched with bare hands? (Choose all correct answers) No. If the crucible is still hot, a student can burn his or her hand. Yes. Gloves can be slippery, making it more dangerous to wear them in lab. Yes. They are easier to transport to the balance room and bare hands do not introduce error into the experiment. No. Dirt and oils on hands can add to the mass of the crucible.
