After James Chadwick discovered the neutron, atomic theory expanded to include isotopes. Isotopes have many practical uses. For
example,
scientists use the relative amount of carbon-12 to carbon-14 in ancient bones to determine how old they are.
How many neutrons are in an atom of Carbon-147
A 2
B 6
C 8
D 14

Answer and Explanation:
For the following balanced reaction:
PCl₅(g) ↔ PCl₃(g) + Cl₂(g)
We can see that all reactants and products are gases, so it is an homogeneous equilibrium. The expression for the equilibrium constant Kp can be written from the partial pressures (P) of reactants and products as follows:
Where PPCl₃ is the partial pressure of PCl₃ (reactant), PCl₂ is the partial pressure of Cl₂ (reactant) and PPCl₅ is the partial pressure of PCl₅ (product).
