Answer: The percent yield of the reaction is 74 %
Explanation:
To calculate the number of moles, we use the equation:
.....(1)
For oxygen gas:
The chemical equation for the reaction of titanium and chlorine gas follows:
By Stoichiometry of the reaction:
4 moles of aluminium reacts with 3 moles of oxygen.
So, 0.092 moles of aluminium reacts with = of oxygen
As, given amount of oxygen is more than the required amount. So, it is considered as an excess reagent.
Thus, aluminium is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
4 moles of aluminium produce = 2 moles of
So, 0.092 moles of aluminium will produce = of
Now, calculating the mass of aluminium oxide:
To calculate the percentage yield of titanium (IV) chloride, we use the equation:
Experimental yield = 3.5 g
Theoretical yield = 4.7 g
Putting values in above equation, we get:
Hence, the percent yield of the reaction is 74 %
