A general description of the single replacement reaction in this experiment is: metal + salt in solution --> 'new' metal + 'new' salt solution. Give a balanced equation for another example of this type of single replacement reaction.
a. Zn + Cu(NO₃)₂ --> Zn(NO₃)₂ + Cu
b. Fe + HCl --> FeCl₂ + H₂
c. Na + H₂O --> NaOH + H₂
d. Mg + AgNO₃ --> Mg(NO₃)₂ + Ag
