Document Summary

The last three pages consist of an equation sheet, data tables and a periodic table. Feel free to carefully remove these and use them. What is the partial pressure of cl2(g), in mm hg, at 273k and 1. 00 atm in a. 46. 5g n2 x 1mole/28g = 1. 66 mole n2. 21. 7 g ne x 1mole/20. 2g = 1. 07 mole ne. 40. 8 g cl2 x 1 mole /71g = 0. 575 moles cl2. Pcl2 = cl2xptotal = 0. 575/3. 306 x ptotla = 0. 175 x ptotal = 0. 175 atm. There is an error in the problem that i had not noticed when i copied it. The answer key is written for the problem with this error. Some students noticed and asked me about this. I told them to use the numbers provided and not to worry about this. December 9, 2013: the combustion of hydrogen/oxygen mixtures is used to produce very high temperatures (approximately 2500 c) that can be used for welding.
