Answer:
the bowling ball will move fastest
Explanation:
because it is heaviest
Aniline has smallest Rf value on silica gel since it is more polarthan the other compounds because aniline is a hydrogen donor and acceptor itmakes the molecule more attracted to the silica gel which is also also polar as<span>‘likes dissolve likes.’</span>

The third reason helped Rutherford to discover the nucleus.
Answer:
Explanation:
Total pressure of the mixture = 300 mm Hg
equation of reaction
C₇ H₁₆(g) + 11 O₂ (g) → 7 CO₂(g) + 8 H₂O(g)
partial pressure of heptane = mole fraction heptane × total pressure = 1 / 12 × 300 mm Hg = 25 mm Hg
partial pressure of oxygen = mole fraction oxygen × total pressure = 11 / 12 × 300 mm Hg = 275 mm Hg
After the reaction
total number of mole before the reaction = 12
total number of mole after the reaction = 15
temperature and volume did not change
if 12 to 300 mm Hg
15 will be 15 × 300 / 12 = 375 mm Hg
partial pressure of water vapor = mole fraction of water vapor × 375 mm Hg = 8 / 15 × 375 mm Hg = 200 mm Hg
