Question: Spinel is a mineral that contains 37 9 aluminum 17 1 magnesium
Spinel is a mineral that contains 37.9% aluminum, 17.1% magnesium, and 45.0% oxygen, by mass, and has a density of 3.57 g/cm3. The edge of the cubic unit cell measures 809 pm. How many of each type of atom are present in the unit cell?
Answer to relevant QuestionsA metallic solid with atoms in a face-centered cubic unit cell with an edge length of 392 pm has a density of 21.45 g/cm3. Calculate the atomic mass and the atomic radius of the metal. Identify the metal. A sample of dry nitrogen gas weighing 100.0 g is bubbled through liquid water at 25.0oC. The gaseous mixture of nitrogen and water vapor escapes at a total pressure of 700. torr. What mass of water has vaporized? (The vapor ...You and a friend each synthesize a compound with the formula XeCl2F2. Your compound is a liquid, and your friend’s compound is a gas (at the same conditions of temperature and pressure). Explain how the two compounds with ...Consider two different compounds, each with the formula C2H6O. One of these compounds is a liquid at room conditions and the other is a gas. Write Lewis structures consistent with this observation, and explain your answer. Hydrogen peroxide (H2O2) is a syrupy liquid with a relatively low vapor pressure and a normal boiling point of 152.2oC. Rationalize the differences between these physical properties and those of water.
