Help on chemistry problems for final. Thanks.?

1. Titanium (III) chloride, a substance used in catalysts for preparing polyethylene, is made by high-temperature reaction of TiCl4 vapor with H2:2TiCl4(g) + H2(g) –> 2TiCl3(s) +2HCl(g)Part A: How many grams of are needed for complete reaction with 135 L of H2 at 430°C and 795 mm Hg pressure? Part B: How many liters of HCl gas at STP will result from the reaction described in part (a)?

Moles H2 = pV/RT = 1.05 atm x 135 L / 0.08206 x 703 K =2.46the ratio between H2 and TiCl4 is 1 : 2moles TiCl4 needed = 2 x 2.46 = 4.92mass TiCl4 = 4.92 mol x 186.692 g/mol=933.3 gMoles HCl produced = 2.46 x 2 = 4.92 At STP 1 mole occupies 22.4 LVolume HCl = 4.92 x 22.4=110.2 L... Show More
