Final answer:
The net ionic equation for sodium carbonate and calcium chloride is Na2CO3 + 2CaCl2 → 2NaCl + CaCO3.
Step-by-step explanation:
The net ionic equation for sodium carbonate and calcium chloride is option c) Na2CO3 + 2CaCl2 → 2NaCl + CaCO3. To determine the net ionic equation, we first need to write the complete ionic equation, which shows all of the dissolved ionic compounds as dissociated ions. The complete ionic equation for sodium carbonate and calcium chloride is:
2Na+ + CO3²- + 2Ca²+ + 4Cl- → 2Na+ + 2Cl- + CaCO3
Next, we cancel out the spectator ions, which are ions that appear on both sides of the equation and do not participate in the reaction. In this case, the spectator ions are Na+ and Cl-. The resulting net ionic equation is:
CO3²- + 2Ca²+ → CaCO3
