(a)
Interpretation:
The number of protons and electrons in a N2 molecule needs to be deduced
Concept Introduction:
- Every system found in nature is a composite of atoms, molecules, ions or other particles
- These are composed of fundamental subatomic particles: protons, neutrons and electrons.
- Each atom is characterized by two quantities:
Atomic number (Z) andatomic mass (A)
Z = atomic number = number of protons = number of electrons ------ (1)
A = atomic mass = number of protons + number of neutrons ------ (2)
For an ion: number of electrons = number of protons + charge on the ion ------ (3)

- One liter of chlorine gas at 1 atm and 298 K reacts completely with 1.00 L of nitrogen gas and 2.00 L of oxygen gas at the same temperature and pressure. A single gaseous product is formed, which fills a 2.00 L flask at 1.00 atm and 298 K. Use this information to determine the following characteristics of the product:(a) its empirical formula;(b) its molecular formula;(c) the most favorable Lewis formula based on formal charge arguments (the central atom is N);(d) the shape of the molecule.arrow_forwardHow does the square root mean square velocity of gas molecules vary with temperature?
