[Answer] (3) Compound B has lower melting and boiling points than compound A. At the same temperature compound B vaporizes faster than compound A. If one of these compounds is ionic and the other is molecular which would you expect to be molecular? ionic? Explain your reasoning.

Answer: “In fact many molecular compounds are already completely gaseous at room temperature. In contrast the ions in ionic compounds are held together by strong attractive forces so ionic compounds generally have higher melting and boiling points than do molecular compounds.” Page 193(215 of 971)Compound B= Molecular compound(Vaporizes faster and has a lower boiling/melting point)Compound A= Ionic compound(Vaporizes slower and has a higher boiling/melting point)

Ununennium also known as eka-francium or element 119 is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively which are used until the element is discovered confirmed and a permanent name is decided upon. In the periodic table of the elements it is expected to be an s-block element …

We must also note that relativistic effects are causing 9p 1/2 and 8p 3 /2 to behave together as one p-shell and so should not really be compared with how it affects p-shells made of np 1/2 and np 3 /2 subshells with the same n. This p-shell is predicted to behave like the 2p and 3p ones so that the full shell of 172 is stabilized (making it a …

Form compounds with oxidation state = d 10 ions (e.g. Cd 2+ In 3 + Sn 4+) but these are less ionic in character than pre-TMs. In solution post-transition metals form stronger complexes than pre-transition metals; lower oxidation states also common (e.g. Tl + Sn 2+ ).

Methane (US: / ˈ m ɛ θ eɪ n / or UK: / ˈ m iː θ eɪ n /) is a chemical compound with the chemical formula CH 4 ( one atom of carbon and four atoms of hydrogen).It is a group-14 hydride and the simplest alkane and is the main constituent of natural gas.The relative abundance of methane on Earth makes it an economically attractive fuel although capturing and storing it poses technical …
