Question:

Calcium oxide reacts with nitric acid (HNO{eq}_3{/eq}) to form aqueous calcium nitrate and water.

{eq}\rm CaO (s) + 2HNO_3 (aq) \to Ca(NO_3)_2 (aq) + H_2O(l) {/eq}

0.4262 g of calcium oxide is reacted with 0.1250 L of 0.06000 M nitric acid.

(a) Write the net ionic equation of the reaction.

(b) Calculate the moles of calcium oxide and nitric acid.

(c) Identify the limiting reagent.

Answer: _____ is the limiting reagent.

(d) Assuming complete reaction, determine the amount of excess reagent in moles that remains in the reaction.

Net Ionic Equation:

A net ionic equation is a chemical equation for a chemical reaction which lists only species, typically ionic reactants, participating in the reaction, eliminating spectator ions. A full ionic equation shows all ions participating including the spectator ions.

Answer and Explanation:


The given balanced chemical reaction equation is:

{eq}\rm CaO(s) + 2HNO_3(aq) \rightarrow Ca(NO_3)_2(aq) + H_2O(l) {/eq}

(a) The net ionic...
