Use the value of the constant obtained to calculate the concentrations of the species at equilibrium
if 2.65 millimoles of Cl₂, 3.1 millimoles of Br2, and 1.44 millimoles of BrCl are introduced into an
empty container of 185 cm³, maintaining the temperature at 350 °C
Ignoring trace elements, a typical elemental composition (by mass) of the human body is as follows:
10.5 % H
66.3 % O
19.9 % C
3.3 % N
Use these percentages, the molar mass values, Avogadro's number, and the atomic numbers to determine the total number of electrons (and protons) in a 73-kg human body (160 pounds).
If these electrons and protons were placed 100 m apart (the distance of approximately one football field), then what would be the force of electrical attraction between them.
