Limiting Reactant Question..A Little help needed

Consider equation:
Ga2S3(g) + 6H2O (l) ---- 2Ga(OH)2 (s) + 3H2S (g)

Assume that 35.0g of Ga2S3 and 13.0g H2O are allowed to react...
(a) determine limiting reagent! --- FIGURED THIS OUT (it's H2O)
(b) calculate mass of hydrogen sulfide (do i use limiting reagent?)
(c) calculate mass of gallium hydroxide (do i use limiting reagent here too?)

just quick yes and no answers will help me out...thanks!

hahha i need this in a few hours...

Yeap, the limiting reagent is H20, and all calculations onwards will base on the limiting reagent.

hey thanks a lot God bless! sorry for the multiple posts on this thread haha

You'd use the limiting because that's the max that could be possibly produced. Its like saying you filled a 1000mL graudated cylinder with 5000mL if you used the excess reactant

ahhh makes sense...good look

Haha maybe ill try...

I wonder how you could figure anything if the reaction is not balanced

Your equation isn't balanced...
