1. In the table below, determine the appropriate density, concentration or molar mass that will be used for each reactant in parts IV and V. Show how you determined the limiting reagent for ONE part (IV or V). Show all your work with units.

Part	Reactant	Density (g/mL) or Concentration (M) or Molar Mass (g/mol)	Moles* (mol)	Moles of product formed**(mol)	Limiting Reactant (record limiting or excess)
IV	HCl
Ca
V	HCl
Mg

* = Carry extra decimals here, ** Based on limiting reagent

Part IV: Ca(s) + 2H⁺ (aq) ---> Ca²⁺ (aq) + H2(g)

Part V: Mg(s) + 2H⁺ ---> Mg²⁺(aq) + H₂(g)
