Answer:

a. CH4 is only held together by London dispersion forces since any dipoles cancel out due to symmetry. On the other hand H2O  has strong hydrogen bonds

b. PH3 has dipole-dipole forces while NH3 is held together by stronger hydrogen bonding

c. C2H6 and C3H8 . Both substances are held together by London dispersion forces since any dipoles cancel out due to symmetry. However C3H8 has the stronger London dispersion forces of the two because it is a larger molecule,

d. BH3 is held together by London dispersion forces since any dipoles cancel out due to symmetry while OF2​ is held together by stronger dipole-dipole forces

50 J of work was done on a system, as a result of which 29 J of heat energy was removed from it. How would this affect the inter
cricket20 [7]
  • Work done=50J
  • Heat removed=29J

Now

\\ \sf\longmapsto \Delta E=50-29

\\ \sf\longmapsto \Delta E=21J

  • Hence the internal energy would increase by 21J

Option B is correct

asambeis [7]
Answer is: <span>volume of balloon is </span>476,85 cm³.
density of air: d(air) = -0,0043 · 18,0°C + 1,2874.
d(air) = 1,21 kg/m³ = 1,21 · 10³/ 10⁶ = 0,00121 g/cm³.
m(balloon) = 0,577 g.
d(balloon) = d(air).
d(balloon) = m(balloon) ÷ V(balloon).
V(balloon) = m(balloon) ÷ d(balloon)
V(balloon) = 0,577 g ÷ 0,00121 g/cm³.
V(balloon) = 476,85 cm³.
