Question

In Earnest Rutherford's experiment, he fired alpha particles through a piece of gold foil. An alpha particle consists of a cluster of two protons and two neutrons, protons and neutrons each have a mass of about 1.67 Times 10^-27 kg. The alpha particles are travelling at around 5.0 Times 10^4 m/s, with an unce rtainty of 5%. Given this information, what would be the untertainty in the position of the alpha particles? Would thisuncertainty be significant? A wavefunction hast eh formula psi =.2 sin pi x. What is the probability that the particle will be found within the region bounded by x = 0.15 and x = 0.85? Molality is moles of solute divided by liters of solution liters of solvent kilograms of solution kilograms of solvent Which of these solvent pairs would form close to a ideal solution. water and ethanol hexane and heptanes The partial pressure of the vapor of the first solvent divided by the sum of the partial pressures of the vapors of two solvents in solution equals The partial pressure of the vapor of the first solvent divided by the vapor pressure of that solvent when it is pure equals Which of these terms is not found in the expression for the freezing point depression cryoscopic constant? Molar mass of the solvent melting point of the solvent

Explanation / Answer

a) Kilograms of solvent

b) Hexane and heptane

c) vapor molefraction of the first solvent

d) liquid molefraction of first solvent

e) Density of solvent
