Concept explainers
Interpretation:
Molar mass and molecular formula of compound with empirical formula
Concept Introduction:
Subscript of empirical formula is multiplied by value of
Effusion is explained as movement of the gas molecule through small hole.
Diffusion can be explained as when one gas molecule mix with another gas molecule by random motion.
Graham’s law of effusion gives relation of rate of effusion with molar mass. Rate of effusion and square root of molar mass are inversely related. The mathematical expression is as follows:

- One of the chemical controversies of the nineteenth century concerned the element beryllium (Be). Berzelius originally claimed that beryllium was a trivalent element (forming Be3+ ions) and that it gave an oxide with the formula Be2O3. This resulted in a calculated atomic mass of 13.5 for beryllium. In formulating his periodic table, Mendeleev proposed that beryllium was divalent (forming Be2+ ions) and that it gave an oxide with the formula Be2O3. This assumption gives an atomic mass of 9.0. In 1894, A. Combes (Comptes Rendus 1894, p. 1221) reacted beryllium with the anion C5H7O2and measured the density of the gaseous product. Combess data for two different experiments are as follows: I II Mass 0.2022 g 0.2224 g Volume 22.6 cm3 26.0 cm3 Temperature 13C 17C Pressure 765.2 mm Hg 764.6 mm If beryllium is a divalent metal, the molecular formula of the product will be Be(C5H7O2)2; if it is trivalent, the formula will be Be(C5H7O2)3. Show how Combess data help to confirm that beryllium is a divalent metal.arrow_forwardYou have an equimolar mixture of the gases SO2 and O2, along with some He, in a container fitted with a piston. The density of this mixture at STP is 1.924 g/L. Assume ideal behavior and constant temperature and pressure. a. What is the mole fraction of He in the original mixture? b. The SO2 and O2 react to completion to form SO3.

Calculate the partial pressure exerted by water vapor at this concentration. Assume that this represents a situation with 100% humidity. What temperature would be needed to achieve this value?

- Silicon nitride, Si3N4, is a material that is used in computer chips as an insulator. Silicon nitride can be prepared according to the chemical equation 3SiH4(g)+4NH3(g)Si3N4(g)+12H2(g) If you wanted to prepare a surface film of Si3N4(s) that had an area of 9.0 mm2 and was 4.0 105 mm thick, what volume of SiH4 gas would you need to use at 1.0 105 torr and 775 K?
