- What are the two most abundant elements by mass in the earths crust, oceans, and atmosphere? Does this make sense? Why? What are the four most abundant elements by mass in the human body? Does this make sense? Why?arrow_forwardArrange the following in the order of increasing mass. (a) a potassium ion, K+ (b) a phosphorus molecule, P4 (c) a potassium atom (d) a platinum atomarrow_forwardUranium-238 (U238) has three more neutrons than uranium-235 (U235). Compared to the speed of sound in a bar of U235, is the speed of sound in a bar of U238 higher, lower, or the same? There are several factors that play a role. (a) Chemically, the atoms of these two isotopes behave in essentially identical ways, since the number of protons (92) is identical and the clouds of 92 electrons are nearly identical. The interatomic distance, and the effective "stiffness" of the interatomic bond, both depend on the chemical properties of the atoms. Therefore, which of the following statements are true? O The effective stiffness of the interatomic "spring" is greater for U238 because the mass is greater. O The effective stiffness of the interatomic "spring" is the same in the two isotopes, since this "spring" is a model for the interactions of the outer electrons, which are the same for different isotopes of the same atom. O An atom with more mass in the nucleus is bigger, so the distance…arrow_forward
- A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of ruthenium in these samples: isotope 101 Ru 102 Ru mass relative (amu) abundance 100.9 53.% Use these measurements to complete the entry for ruthenium in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits.

The compound is so intensely coloured that even a small amount of it makes for a black or dark blue suspension. Given that this antidote has never before been administered at the hospital, none of the doctors or nurses have experience with it. There is one very old bottle of Fe-(CN)18 pills in the medicine store-room, but the label is worn and the units are in the old, archaic British Apothecaries' system which has unusual units like drachms, scruples, grains, and mites: 453.6 grams (g) = 1 pound (Ib) = 12 ounces (3) = 96 drachms (3) = 288 scruples (3) = 5760 grains (gr) = 115200 mites (m)arrow_forwardPredict the products of the reaction below.

- A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18, the mass of oxygen-16 is 2.66 ✕ 10−26 kg, and they are singly charged and travel at 7.40 ✕ 106 m/s in a 1.40 T magnetic field. What is the separation (in m) between their paths when they hit a target after traversing a semicircle?arrow_forwardA robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System.
