Identify the limiting reagent when 6.00 g HCl combines with 5.00 g Mg to form MgCl2.
Mg + 2HCl --> MgCl2 + H2
Mg
H2
MgCl2
HCl
Cl2 + 2 KBr → Br2 + 2 KCl

Why is it important to identify the limiting reagent?
The limiting reagent speeds up the reaction.
The limiting reagent controls the amount of product formed.
If there is no limiting reagent, the reaction will not occur.
No stoichiometry calculations can be done without a limiting reagent.
