What is the net ionic equation for the reaction between zinc (Zn) and magnesium ions (Mg^2+)?
A
Zn + Mg^2+ → Zn + Mg^2+
B
Zn + Mg^2+ → Zn^2+ + Mg
C
Zn^2+ + Mg → Zn + Mg^2+
D
Zn + Mg → Zn^2+ + Mg^2+
Verified step by step guidance1
Identify the reactants and products in the given chemical equation: Zn and Mg^2+ are the reactants, while Zn^2+ and Mg are the products.
Write the balanced molecular equation for the reaction: Zn(s) + Mg^2+(aq) → Zn^2+(aq) + Mg(s).
Determine the states of matter for each species: Zn is a solid (s), Mg^2+ is aqueous (aq), Zn^2+ is aqueous (aq), and Mg is a solid (s).
Identify the ions that are involved in the reaction: Zn is oxidized to Zn^2+ and Mg^2+ is reduced to Mg.
Write the net ionic equation by removing the spectator ions (if any) and focusing on the species that undergo a change: Zn(s) + Mg^2+(aq) → Zn^2+(aq) + Mg(s).
