At what temperature would 0.05 moles of nitrogen gas occupy 1000cm^3 at 50kPa?

Ideal gas equation: pV=nRT Rearrange to get T: T=pV/nR Convert pressure to Pa: 50 x 1000 = 50,000 Convert volume to m^3: 1000 / (100)^3 = 0.001 Insert to find temperature: T = (50,000 x 0.001) / (0.05 x 8...

Draw the shape of an SF6 and SF4 molecule, indicating bond angles and any lone pairs which may influence these. What shape is the SF6 molecule?

Sulfur is a group six element, meaning it can form up to six bonds with halogen atoms such as F or Cl. In the instance where only four valence electrons of S are bonded to the halogens, the remaining two ...
