Question

Consider the unbalanced reaction Ti(s) + Cl2(g) --> TiCl4(s)

When 10.3 g of Ti react with 12.7 g of Cl2, 16.2 g of TiCl4 are obtained. The theoretical yield of TiCl4 is
, the limiting reactant is
and the percent yield is
%. (Remember to use correct sig figs)

Answer 1

Balanced equation: Ti + 2Cl2 --> TiCl4
To find the limiting reactant find the moles of Ti and Cl2. Remeber that theres 2 moles of Cl2. The one with the lowest amount of moles is the limiting reactant.
Next use the moles of the limiting reagent to find to theoretical mass yield. You do this by converting the limiting reactants moles to the moles of TiCl4 and then multiply by the molecular mass of TiCl4 to find the theoretical mass.
% Yield= (Theoretical mass/16.2) *100

Answer 2

Sorry the % yield is = (16.2/ theoretical yield) *100
