Answer to Question #249215 in General Chemistry for sgahbee

Question

Titanium is a transition metal used in many alloys because it is extremely strong and lightweight. Titanium tetrachloride (TiCl4) is extracted from titanium oxide (TiO2) using chlorine and coke (carbon). What is the mass of Cl2 gas is needed to react with 1.25 mol of TiO2?

Answer 1

The reaction is represented by the following equation:

TiO₂ + 2Cl₂ + C --> TiCl₄ + CO₂

Therefore,

$m(Cl_2)=1.25mol(TiO_2)\times\frac{2mol(Cl_2)}{1mol(TiO_2)}\times\frac{70.91g(Cl_2)}{1mol(Cl_2)}=177g$

Answer: 177 g
