Here are the answers to your questions:
Question 1
A) Which option describes a situation in which reduction occurs?
- Answer: S becoming S²⁻ - This indicates that sulfur is gaining electrons (from S to S²⁻), demonstrating reduction.
Question 2
A) Does this equation represent a redox reaction?
- Answer: Yes, it does because hydrogen (H) undergoes reduction and silver (Ag) undergoes oxidation. - In this reaction, silver is oxidized (losing electrons) and hydrogen is reduced (gaining electrons).
Question 4
A) Which product forms when two or more nonmetal atoms share valence electrons?
- Answer: a covalent compound - When nonmetals share electrons, they form covalent bonds, resulting in covalent compounds.
Question 5
A) Which phrase best defines a galvanic cell?
- Answer: an object that produces electrical energy through redox reactions - A galvanic cell works by converting chemical energy to electrical energy through redox reactions.
Question 6
A) Which phrase best describes oxidation?
- Answer: loss of electrons - Oxidation is defined as the loss of electrons by an atom or molecule.
