(7 pts) hydrogen and chlorine atoms react to form simple diatomic molecules in a 1: 1 ratio that is hcl. the natural abundances of the chlorine isotopes are 75.77% 35cl and 24.23% 37cl. the natural abundance of 1h is 99.985%, the natural abundance of 2h is 0.015% and there is only a trace (less than 0.001%) of 3h. (a) how many different peaks can hcl produce in a mass spectrometer and what is the mass number for each peak observed? (b) what is the relative abundance of each mass. (c) sketch the mass spectrometry analysis output (relative number of atoms vs mass number) for an hcl sample.

In which of these cases are the two wave points considered to be in phase with each other?

What is the empirical formula of a compound that is 50.7% antimony and 49.3% selenium ?

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
