In my lab class, we did a flame test using a bunch of different metal ions. Of all of the metal ions we tested, Na gave the brightest color and burned the longest (it was a bright orange). Do you think that potassium (it was a whitish-purple) could be detected by the human eye in the presence of Na by burning the two in a flame?

I have an ethylene stream with a lot of trace impurities in it. For all of them except ammonia I can use a Gas Chromatograph with a FID (Flame Ionization Detector). In the case of ammonia a FID will not work. What type of detector would be best suited for ammonia (5-0.1 ppmv range). I also looked at a NPD (Nitrogen Phosphorus Detector) but it seems to only be good for nitrogen containing organic compounds. Any help (and sources) would be appreciated.

1) What is the mass of 1.33 x 10^4 moles of O2 at STP??

2) Write a balences equationfor the following;
hydrogen gas + oxygen gas -> water vapor
hydrogen gas + chlorine gas -> hydrogen chloride gas

3) A chemist determines the mass of a sample of gas to be 3.17g. It's volume is 942 ml at 14 C (degrees) and 1.09 atm. What is the moler mass of the gas?

If you can help me out..... How did you get your answers, I AM SO LOST right now.... and I knida need help with this stuff from where I can get it.

Please and Thank You!!!
