Question

TiO2(s) + H2(g) Ti(s) + H2O(g)

(a) Consider the unbalanced equation above. What is the maximum mass of titanium that can be produced when 2.65 g of TiO2 and 3.40 g H2 react?
= ?g Ti
(b)Assume the reaction in part (a) goes to completion. Calculate the mass of excess reactant.
=?g

Answer 1

There is a missing arrow --> in your reaction.

Your first step should be to balance the reaction. You will twice as many H2's as O2's to remove the O atoms from TiO2

Someone be glad to critique your work.
