2.c.1.2.......
Write a total ionic equation and a net ionic equation for each of the following reactions:

a. HCl(aq)+NaOH(aq) -> NaCl(aq)+H2O(l)
b. Mg(s)+2HCl(aq) -> MgCl2(aq)+H2(g)
c. CuCl2(aq)+Na2CO3(aq) -> 2NaCl(aq)+CdCO3(s)

Please format with

Problem (Letter):
Steps:
Answer:
1. (total ionic equation)
2. (net ionic equation)

Thanks!
PS: This is not my HW! This is for test corrections

-
a. HCl(aq) + NaOH(aq) -> NaCl(aq) + H2O(l)
1. H+ + Cl- + Na+ + OH- ----> Na+ + Cl- + H2O(l) (liquids/ molecules cannot break apart, must be aqueous)
2. H+ + OH- -----> H2O(l) (eliminate all spectator ions)

b. Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
1. Mg(s) + 2H+ + 2Cl- ----> Mg2+ + 2Cl- + H2(g)
2. Mg(s) + 2H+ ----> Mg2+ + H2(g)

c. CuCl2(aq) + Na2CO3(aq) ----> 2NaCl(aq) + CdCO3(s)
1. Cu2+ + 2Cl- + 2Na+ + CO3(2-) ----> 2Na+ + 2Cl- + CdCO3(s) [the (2-) is the charge of CO3
2. Cu2+ + CO3(2-) -----> CdCO3(s)
