Be sure to answer all parts. 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 7.46 g of SrH2 and 6.22 g of H2O.

(a) How many moles of H2 can be produced from the given mass of SrH2?

moles

(b) How many moles of H2 can be produced from the given mass of H2O?

moles

(c) Which is the limiting reactant?
H2O
SrH2

i think   the answer is c hope i'm right

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
