1) Which option describes a situation in which reduction occurs?(1 point)
S2– becoming S
Cl2 becoming Cl–
Al becoming Al3+
Xe2+ becoming Xe6+
2) Use the chemical equation to answer the question.
2Ag(s) + H2S(g) → Ag2S(s) + H2(g)
Does this equation represent a redox reaction?
No, it does not because neither hydrogen (H) nor silver (Ag) transfers electrons.
Yes, it does because silver (Ag) undergoes reduction and hydrogen (H) undergoes oxidation.
Yes, it does because hydrogen (H) undergoes reduction and silver (Ag) undergoes oxidation.
No, it does not because sulfur (S) does not change oxidation states.
3) Which product forms when two or more nonmetal atoms share valence electrons?
a monoatomic ion
a redox reaction
an ionic compound
a covalent compound
4) Which phrase best defines a galvanic cell?
an object that converts stored chemical energy into electrical energy
an object that makes electrical connections
an object that oxidizes atoms to produce ions
an object that produces electrical energy through redox reactions
