Label the dimensional analysis according to the stoichiometry problem: 12.2 mol of C5H6 combusts to form CO2 and H2O, how many moles of Oxygen used? 2C5H6 + 13O2 → 6H2O + 10CO2

How much would the freezing point of water decrease if 4 mol of sugar were added to 1 kg of water(k=1.86 c/mol/kg for water and i=1 for sugar

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
