Which one of these compounds listed below is least likely to exist, and why? nabr hgcl2 arcl mg3n2 c3h8 cao

Argon chloride, ArCl is least likely to exist.

Argon belongs to the noble gas family. It has an atomic number of 18 and a valence electron configuration: 3s²3p⁶. Since the valence shell is completely filled i.e. it already has an octet configuration, this makes it stable and chemically inert. When approached closely by another element, Cl in this case, the fully filled valence shell of Ar would repel the incoming electron cloud. The only bond that could exist is the extremely weak, long-range Vander-Waals bond between Ar and Cl.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.

ill try to . no promises tho.
