Not sure what you exactly mean, but I think what you are talking about are the spheres of earth (Lithosphere, Hydrosphere, Atmosphere, and Biosphere.)
Lithosphere (Terrestrial) is the land on earth. Hydrosphere (Hydrologic) is the water on earth.
I'm not sure if this is 100% correct but I'm guessing this is what you are referring to. It could be different across different science classes.
Answer:
Molecular formula is C21H40
Explanation:
Use the formula CnH2n-2
That is the alkyne formula
Many of the elements on the periodic table will always form ions that have the same charge. The alkali metals (shown in yellow) always form +1 ions. The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions.
Answer:
[CO2] > [N2] > [He]
Explanation:
The relative concentration of CO2, N2 and He depends on the solubility of each gas in water. The more soluble in water a gas is, the greater its concentration in aqueous solution.
Among the gases listed, CO2 is most soluble in water hence it is expected to have the greatest concentration in solution followed by N2. Helium gas is insoluble in water hence it has the least concentration in the aqueous solution.
