Answer:
(a) Iron is being oxidized.
(d) Sulfur is being reduced.
Explanation:
Let's consider the following redox reaction.
8 Fe(s) + S₈(s) → 8 FeS(s)
Iron is being oxidized according to the following oxidation half-reaction:
Fe(s) → Fe²⁺(s) + 2 e⁻
Sulfur is being reduced according to the following reduction half-reaction:
S₈(s) + 16 e⁻ → 8 S²⁻(s)
Are u sure this is the right option? Well, antimony can be decomposed. Including octane.
Answer:
elements have the same number of valence electrons and similar chemical properties.
Explanation:
they have the same number
Atomic mass Ti = 47.867 a.m.u
47.867 g ---------------- 6.02x10²³ atoms
33 g --------------------- ??
33 x ( 6.02x10²³) / 47.867 => 4.15x10²³ atoms
Answer D
hope this helps!
