For the reaction 2 CI2(g) + 4 NaOH(aq) → 3 NaCl(aq) + NaCIO2(aq) + 2H2O(I) 11.9 g CI2 is reacted with 12.0 g NaOH. Determine which is the limiting reactant. Show your work and explain your reasoning.

The names and symbols for the transition elements used in the fictional kingdom of Narnia are different from those used by the rest of the planet, except for silver, cadmium, and zinc. For the rest of the elements and chemical entities, the kingdom uses the same names and inorganic nomenclature rules as used by the rest of the world. If the name used for a transition metal is “narnium” (symbol Nr), what would be the name of NrSO4 in the kingdom of Narnia? Explain your reasoning.
