Chapter 3, Problem 49P(choose chapter or problem)
Metal hydrides react with water to form hydrogen gas and the metal hydroxide. For example,
\(\mathrm{SrH}_{2}(\mathrm{~s})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{Sr}(\mathrm{OH})_{2}(\mathrm{~s})+2 \mathrm{H}_{2}(\mathrm{~g})\)
You wish to calculate the mass of hydrogen gas that can be prepared from \(5.70 \mathrm{~g} \text { of } \mathrm{SrH}_{2}\) and \(4.75 \mathrm{~g} \text { of } \mathrm{H}_{2} \mathrm{O}\).
How many moles of \(\mathrm{H}_{2}\) can form from the given mass of \(\mathrm{SrH}_{2}\)?
How many moles of \(\mathrm{H}_{2}\) can form from the given mass of \(\mathrm{H}_{2} \mathrm{O}\)?
Which is the limiting reactant?
How many grams of \(\mathrm{H}_{2}\) can form?

Step by Step Solution
Step 1 of 6
Metal hydrides are the ionic compounds formed by the combination of metal and hydrogen atoms. In metal hydrides metal takes a positive charge and hydrogen acquires a negative charge.
