Stoichiometry

Post by brwhite »

2.914 grams of aqueous magnesium sulfide reacts with 11.227 grams of aqueous titanium (iv) nitrate.

1.) Predict the products and balance the equation.
---I came up with this as the answer--- 4MgS+Ti(NO3)4 = 4Mg(NO3)+TiS4 with Mg(NO3) and TiS4 being the predicted products

2.) Use a solubility chart to determine which products are insoluble. Add correct states of matter to your equation.

3.) Using the given amounts of reactants determine the following:
a) limiting and excess reactants
b) amount of solid product that can be made in both moles and grams
c)% yield (when a student did this in a lab, they got 1.15 grams of product)

I've tried looking into reactions between MgS and Ti(NO3)4 but haven't managed to find much of anything on it. I also can't find anything on TiS4 and instead get information on TiS2 when I try looking it up. So any help in solving this assignment would be greatly appreciated!

Check the oxidation number of Mg and also sulfur. There you have the errors.
