Chapter 2, Problem 2.106QP
In a hypothetical universe, an oil-drop experiment gave the following measurements of charges on oil drops: −5.55 × 10−19 C, −9.25 × 10−19 C, −1.11 × 10−18 C, and −1.48 × 10−18 C. Assume that the smallest difference in charge equals the unit of negative charge in this universe. What is the value of this unit of charge? How many units of excess negative charge are there on each oil drop?

- Two basic laws of chemistry are the law of conservation of mass and the law of constant composition. Which of these laws (if any) do the following statements illustrate? (a) The mass of phosphorus, P, combined with one gram of hydrogen, H, in the highly toxic gas phosphene, PH3, is a little more than twice the mass of nitrogen, N, combined with one gram of hydrogen in ammonia gas, NH3. (b) A cold pack has the same mass before and after the seal between two reactants is broken to allow reaction to occur. (c) It is highly improbable that carbon monoxide gas found in Los Angeles is C1.2O1.1.arrow_forwardThe element europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 amu, and 153Eu has a mass of 152.9209 amu. The average atomic mass of europium is 151.96 amu. a. Calculate the relative abundance of the two europium isotopes. b. Graph each fractional abundance value as a y-axis value in association with its corresponding mass value on the x-axis. Starting from each x-axis value, where y = 0, draw a vertical line up to the fractional abundance value. The result will approximate the type of visual graph a mass spectrometer would yield for europium in the 150155 amu range.arrow_forwardWhich of the following is true about an individual atom?
