Problem

Metal hydrides react with water to form hydrogen gas and metal hydroxide. For example, 

SrH2 (s) + 2H2O (l) → Sr(OH)2 (s) + 2H2 (g) 

You wish to calculate the mass of hydrogen gas that can be prepared from 7.27 g of SrH  2  and 6.06 g of H2O. 

(a) How many moles of H2 can be produced from the given mass of SrH 2


(b) How many moles of H2 can be produced from the given mass of H 2O?  


(c) Which is the limiting reactant? 

(d) How many grams of H2 can be produced?
