Usng the following balanced chemical equation, determine the limiting reactant in the reaction between 3.0 grams of titanium and 8.0 grams of chlorine gas?
Ti(s) + 2Cl2(g) --> TiCl4(s)
D In this reaction, there is exactly the stoichiometric amount of each reactant.
Titanium is your limiting reagent in this reaction. The number of mole of Ti in the reaction is less than that of Cl even though the ratio of Ti to Cl is 1:2 Ti will still run out first. 3/48 (RAM of Ti) = 0.0625 moles 8/35 (RAM of Cl) = 0.2286 moles but because of the 1:2 ratio this value must be halved to give 0.1143... 0.1143 is still bigger than 0.0625 so Ti will run out first.
