Part III:
You have found a new element with the atomic mass of 119. In a paragraph explain where you would put in on the periodic table and why you would put it there. What type of properties would this element have? What would you call it?

Iron: Fe

Co: Cobalt

Na: Sodium

Tin: Sn

P: Phosphorus

F: Flourine

Fe: Iron

Magnesium: Mg

Uranium: U

Ca: Calcium

Carbon: C

Lead: Pb

Ag: Silver

Zn: Zinc

Ni: Nickle

There is honestly no right answer for this but here is what I would put:

Atomic mass increases as you go from left to right. If you look at the periodic table, it would be between Sn and Sb. It would bet here because Sn is 118 and Sb is 121. Basing it off of Antimony and putting it in group 15, the properties are that it is metallic and is a poor conductor of heat. I would call it Stin, which would be shortened to St.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
