That will be regarding the water cycle. Write about the importance of the water cycle, each state from evaporation, condensation, precipitation, and run off. How the water cycle affects weather, animals, and the environment.
Different elements emit different spectra when their electrons get excited because each element has a different arrangement of electrons surrounding the nucleus. The energy levels in which the electrons can occupy are unique to a specific element. When an electron gets excited into a higher energy level, it will eventually relax back into its original state and emit light corresponding to that energy.
<span>Air enters through the nose or mouth (which join to form the nasopharyngeal cavity). The air travels through the trachea which and the trachea splits into two bronchi. The air travels through the bronchi which split into smaller and smaller bronchioles. The tiny bronchioles and the air ends up in the miniscule alveoli, where the oxygen in the air diffuse into the bloodstream. Carbon dioxide diffuse from the bloodstream into the alveoli and the unwanted gas travels in reverse back to the nose and mouth, where it is breathed out.</span>
<span>Kp = PH2O^2/(PH2O)^2
To calculate SO2 is to have a Kp for the reaction
let x=PSO2=PH2S
Kp= (28/760atm)^2/x^3
x=cube root(0.03684)/Kp=PSO2</span>
