Essentially the term binary, meaning each different thing has two components. Binary ionic compounds have two ionic compounds, binary molecular compounds have two molecular compounds, and binary acids have two acids.
The volume is 19.76987448 by taking the known variables mass=18.9g and density=0.956g/ml
To get volume you divide the mass by the density which gives you about
19.77 ml in volume
B because those are the elements
Answer:
Bohr's model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy in uncharged. When the atom absorbs one or more quanta of energy, the electron moves from the ground state orbit to an excited stats orbit that is further away. Energy levels are designated with the variable n. The ground state is n =1, the first excited state is n = 2, and so on. The energy that is gained by the atom is equal to the difference in energy between the two energy levels. When the atom relaxes back to a lower energy state, it releases energy that is again equal to the difference in energy of the two orbits.
This is b nuclear energy
Because it turns into gas
