Write the molecular, total ionic, and net ionic, for the reaction.
1). Aqueous sodium carbonate is reacted with aqueous nickle (11) chloride.
2). Aqueous potassium hydroxide is mixed with aqueous hydrochloric acid.
Chemistry 101 -
You add the aq and l and s.
Na2CO3 + NiCl2 ==> 2NaCl + NiCO3(s)
Total ionic equation:
2Na^+ + CO3^2- + Ni^2+ + 2Cl^- ==> 2Na^+ + 2Cl^- + NiCO3(s)
Net ionic equation: Just cancel the ions that are common to both sides. What left is the net ionic equation.
CP3^2-(aq) + Ni^2+(aq) ==> NiCO3(s)
Do the same for the other one.
