The correct answer is -2 oxidation state.
Assume that the oxidation number of the sulfur atom in H2S S is x.Now, 2+x=0 ⇒ x=−2. As a result, the oxidation number of sulfur in H2S is -2. Various organosulfur compounds are produced by combining Hydrogen sulfide with sulfur. Sewer gas, swamp gas, stink damp, and sour damp all include Hydrogen sulphide, an invisible gas. It smells strongly of eggs, even in small amounts. It is extremely flammable and poisonous. While drilling for and producing crude oil and natural gas, gases like Hydrogen sulfide (H2S) are regularly found.

The answer would be letter A
Answer: Pressure from when the mountain formed creates the sedimentary rock.
Explanation: it’s prob wrong but i’m taking the test rn and this is my best guess
11. a. Amphoteric
12. a. NH₄⁺, H₂O
Explanation:
11. A substance that can act as either an acid or a base is said to be <u>amphoteric</u>.
Water is an amphoteric substance because it can reaction with either and acid or a base.
HCl + H₂O → Cl⁻ + H₃O⁺
NH₃ + H₂O → NH₄⁺ + OH⁻
12. What are the acids in the following equilibrium reaction?
NH₃ (aq) + H₂O (l) → NH₄⁺ (aq) +OH⁻ (aq)
H₂O water is acid 1
NH₄⁺ ammonium ion is acid 2

<span>The function of a hypothesis is to create a testable statement. In that, a hypothesis can be followed up by a experiment. Hypotheses can be used in order to determine if there is a result of an affect, this is the independent variable, what you get out is the dependent variable, or the result. There is a control that is used generally as a means to test your hypothesis to a standard.</span>
