Question

PLEASE HELP!
TiO2 + 4Cl2 + 3C → CO2 + 2CO +2TiCl4
How many moles of TiCl4 will be needed to react with 115 moles of Cl2?
A. 230 mol
B. 115 mol
C. 76.7 mol
D. 57.5 mol  

Answer 1

hey there!:

The stoichiometry of the reaction is:

TiO2 + 4 Cl2 + 3C =  CO2 + 2 CO +2 TiCl4

4 moles Cl2 -----------------  2 moles TiCl4 
115 moles Cl2 --------------- moles TiCl4 ??

moles TiCl4 = 115 * 2 / 4 

moles TiCl4 = 230 / 4

=> 57.5 moles of TiCl4

Answer D

hope this helps!

Answer 2

Answer:

The correct answer is option D. 57.5 mol

Explanation:

Hello!

Let's solve this!

The reaction is as follows:

TiO2 + 4Cl2 + 3C → CO2 + 2CO + 2TiCl4

The data is:

mol Cl2 = 115 mol

In the reaction we see that the ratio of moles is 4 moles of Cl2 resulting in 2 moles TiCl4.

This is represented as follows:

4molCl2 ---- 2molTiCl4

115molCl2 ---- xmolTiCl4

So:

molTiCl4 = 115molCl2 * (2molTiCl4 / 4molCl2) = 57.5molTiCl4

We conclude that the correct answer is option D. 57.5 mol
