Sodium nitrate is one kind of color agents in fireworks. Its energy level spectrum is given below. When sodium nitrate is heated, the electrons of the sodium atoms absorb heat energy and become excited. This high-energy excited state does not last for long, and the excited electrons of the sodium atom quickly release their energy, which is the energy of certain light. 1. What's the quantum numbers for states like 5S1/2, 4P3/2 ? Explain them in details. 2. Give the electron configuration / arrangement of sodium ground state. 3. Find the excited state with the lowest energy. Calculate the exact wavelength of this transition using the relation E=hν and c=λν. 4. Tell the color of this emission.

explanation:

specific heat is the amount of heat required to raise the temperature of a unit mass of a substance.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
