# Solution: 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?

###### 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? View Complete Written Solution
