Answer:
The answer to your question is 1124.8 g of TiCl₄
Explanation:
Data
TiCl₄ = ?
Volume of H₂ = 170 l
Temperature = 450°C
Pressure = 785 mm Hg
Process
1.- Convert temperature to °K
Temperature = 273 + 450
Temperature = 723 °K
2.- Convert mmHg to atm
1 atm ---------------- 760 mmHg
x --------------- 785 mmHg
x = (785 x 1) / 760
x = 1.032 atm
3.- Use the Ideal gases law
PV = nRT
solve for n
n = (PV) / (RT)
Substitution
n = (1.032 x 170) / (0.082 x 723)
Simplification
n = 175.44 / 59.29
Result
n = 2.96 moles of H₂
4.- Use the balanced reaction to calculate the moles of TiCl₄ needed
2TiCl₄ + H₂ ⇒ 2TiCl₃ + HCl
2 moles of TiCl₄ ------------- 1 mol of H₂
x -------------- 2,96 mol of H₂
x = (2.96 x 2) / 1
x = 5.92 moles of TiCl₄
5.- Convert moles to grams
190 g of TiCl₄ ---------------- 1 mol of TiCl₄
x ----------------- 5.92 moles of TiCl₄
x = (5.92 x 190) / 1
x = 1124.8 g of TiCl₄
Metals usually donates electrons. The concept behind this phenomenon is stability. The elements with the most stable electronic configuration are the noble gases in Group 5A. As a result, the other elements donate or accept electrons so that they would be like the noble gases. Since metals are past their nearest noble gas element, they have to shed their electrons. When they do, they become cations which are positively charged ions.
K → K⁺ + e⁻
where e is an electron donated
