Answer to Question #135509 in Chemistry for lilo

Question

What it the mass concentration of the excess reagent in the non Stoichemtric reaction

(6HCl+2Al ➡2AlCl3+3H2)

Answer 1

The reactant that produces a lesser amount of product is the limiting reagent.

The reactant that produces a larger amount of product is the excess reagent.

To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given.

To find mass concentration of the excess reagent in the non-stochiometric reaction divide mass of this excess reagent to the total sum of reactants and products (except gaseous products).
