## Question:

The alkali metals react with the halogens to form ionic metal halides. What mass of potassium chloride forms when {eq}5.25 \ L {/eq} of chlorine gas at {eq}0.95 \ atm {/eq} and {eq}293 \ K {/eq} reacts with {eq}17 \ g {/eq} of potassium?

## Limiting Reactant:

Most chemical reactions contain several reactants mixed in varying proportions and starting quantities. The reactant in this mixture that has an insufficient number of moles to satisfy the reaction stoichiometry, is called the limiting reactant. It will be fully consumed, while the other reactants present in excess will partially remain after reaction. Determining the limiting reactant requires a balanced reaction equation and all starting reactant quantities converted to moles. Once you determine if a limiting reactant is present, you can determine the theoretical yields of any products formed.

The balanced reaction equation of potassium metal with chlorine gas to form potassium chloride salt is:

{eq}2K (s) + Cl_2 (g) \rightarrow 2KCl (s)...
