ndium antimonide (InSb) detectors are used for thermal imaging, infrared detectors, and heat-seeking missile guidance systems. The antimony metal needed to make indium antimonide is usually found in nature as the mineral stibnite, Sb2S3. Pure antimony can be obtained by first converting the sulfide in stibnite to an oxide, and then heating the oxide with coke (carbon). It can then be converted to indium antimonide via a high temperature reaction with indium metal. The relevant reactions are:2 Sb2S3 (s) + 9 O2 (g) Sb4O6 (s) + 6 SO2 (g)Sb4O6 (s) + 6 C (s) 4 Sb (s) + 6 CO (g)In (s) + Sb (s) InSb(s) How many kilograms of indium antimonide can be obtained from 800 kg of stibnite using this process?How many kilograms of indium metal are required for this reaction?
I suggest the red jersey with white letters and also getting one of linebackers like patrick willis or Aldon Smith two best players on the team i think
Yeah, when you wear glasses under goggles and it's warm or humid in the classroom you have a problem with fog up and the like. There are sports goggles you can get that are safety glasses that look really cool and as long as they meet what is called ANSI (American National Standards Institute) standards for safety eyewear there is no reason they should not allow you to wear them in class. (But I would ask first since the sports goggles with your Rx are going to cost a little money). They can be made without the inserts behind the goggles. If they have any question about their safety at school, tell them to look on the upper temporal edge of the lenses where they will see an imprint of the lab that made the safety lenses (that confirms the lenses were made to ANSI standards).
e-mail . i know they do them but they aren't on their website. they can give you a quote and ship within 3 days (they are based in CT). but be sure to include your Rx in the e-mail so they know how thick the lens will be so they can make a recommendation.
