Concept explainers
a)
Interpretation:Name and molecular formula of compound formed from
Concept introduction:In the molecular formula, the exact number and type of constituent atoms are shown. Type of constituent atoms is represented by their atomic symbols and the number of each constituent atom is represented by right subscript of its atomic symbol. The number of each constituent in a molecule depends on its valency. The valency of an element is calculated from its electronic configuration, that is how many electrons it can lose or gain to attain a stable electronic configuration.

- A sample of metallic element X, weighing 3.177 g, combines with 0.6015 L of O2 gas (at normal pressure and 20.0C) to form the metal oxide with the formula XO. If the density of O2 gas under these conditions is 1.330 g/L, what is the mass of this oxygen? The atomic weight of oxygen is 15.999 amu. What is the atomic weight of X? What is the identity of X?arrow_forwardA sample of metallic element X, weighing 4.315 g, combines with 0.4810 L of Cl2 gas (at normal pressure and 20.0C) to form the metal chloride with the formula XCl. If the density of Cl2 gas under these conditions is 2.948 g/L, what is the mass of the chlorine? The atomic weight of chlorine is 35.45 amu. What is the atomic weight of X? What is the identity of X?arrow_forward2.75 Chlorine has only two isotopes, one with mass 35 and the other with mass 37. One is present at roughly 75% abundance, and the atomic weight of chlorine on a periodic table is 35.45. Which must be the correct mass spectrum for chlorine?arrow_forward
- The mass spectrum of CH3Cl is illustrated here. You know that carbon has two stable isotopes, and 13C with relative abundances of 98.9% and 1.1%, respectively, and chlorine has two isotopes, 35a and 37CI with abundances of 75.77% and 24.23%, respectively.
