Homework Help: Limiting reaction

  1. Mar 6, 2008 #1
    1. Add 25 mL of HCL solution to each flask.
    2. Weigh out 0.15g, 0.3g, and 0.6g of Mg ribbon and place each sample into its own balloon
    1.0moles HCL/1L or 0.1 moles HCL/100mL solution

    Mg + 2HCl --> H2 + MgCl2

    show the calculations determining the limiting reactant for each reaction.

    Help on how to get the limiting reactant!!

    And using the limiting reactant as the starting amount, determine the amount of hydrogen gas that was produced per reaction flask:

    Convert the weight of each reagent to mols, whichever gives the least number of mols is your limiting reagent (don't forget to divide by 2 where appropriate to represent 2 atoms/molecules being required).
