2.22 g of NaF*1mol/41.97g of NaF =0.0529 moles
Answer:
D. CF₄
Explanation:
The compound with this molecular geometry is Carbon tetrafluoride (CF₄)
Carbon tetrafluoride (CF₄) also known as Tetrafluoromethane, is known to be the simplest perfluorocarbon. The compound, tetrafluoromethane is the hydrocarbon methane has been perfluorinated. It useful as a refrigerant but known to be a greenhouse gas. Due to the nature of the carbon-flourine bond, it has very high bonding strength. Its bonds are known to be the strongest single bonds in organic chemistry.
Option D is the correct answer.
Answer:
1s² 2s² 2p⁶ 3s² 3p⁴
Explanation:
Looking at the <em>periodic table</em>, we see that sulfur (S) has an atomic number of 16, this means its electronic configuration would be:
We know the electronic configuration written above is correct because the sum of all the superscript numbers is 16 (2+2+6+3+4=16).
<span>Both contain Sn in 4+ oxidation state. As the charge on the cation is very high, the nature of these compounds will be more covalent. They tend to exist in molecular form rather than in ionic form.
So the attractions between the molecules is weak vander Waal's forces of attractions. These attractions become stronger with more force in the molecular wt.
As the mol. wt of SnI4 is greater than SnCl4, the attractions in SnI4 will be stronger. Hence SnI4 is solid and SnCl4 is a liquid at room temp.</span>
