Question
What has a complete ionic equation of Mg(s) + Zn2+ + 2NO3- Mg2+ + 2NO3- + Zn(s)?A.Mg(s) + Zn2+ Mg2+ + Zn(s)B.Mg(s) + Zn(NO3)2(aq) Mg(NO3)2(aq) + Zn(s)C.Mg(NO3)2 + Zn(s) Zn2+ + 2NO3- + Mg(s)D.Mg(s) + 2Zn(NO3)(aq) 2MgNO3(aq) + Zn(s)
Solution
The correct answer is B. Mg(s) + Zn(NO3)2(aq) Mg(NO3)2(aq) + Zn(s). This is because when Mg(s) reacts with Zn(NO3)2(aq), it displaces Zn2+ from its salt and forms Mg(NO3)2(aq) and Zn(s). This is a type of single displacement reaction. The complete ionic equation shows all of the ions present in the reaction, which matches the given equation.
