Homework Help: Maximum Amount of Ca(OH)2

  1. Sep 13, 2012 #1
    For the reaction

    Ca + 2 H2O → Ca(OH)2 + H2

    what is the maximum amount of Ca(OH)2
    which could be formed from 11.27 g of Ca and
    17.8 g of H2O?
    Answer in units of g

    Would I use the limiting reactant type of format to solve this problem? Like find how much Ca would produce Ca(OH)2 and how much H2O would produce Ca(OH)2 and then my final answer would be my the answer that has the greater value? Is that right? Or am I on the wrong track?

    Yes, you will have to find the limiting reagent. Start by finding the number of moles of the reactants.

    Like the final answer would be the one with the LOWER value.
