Answer:I think it's Geosphere
Explanation:
Option A. Hydrogen Ions
The dissolution of carbon dioxide in the oceans produce hydrogen ions as when carbon dioxide is dissolved in the ocean it leads to Ocean Acidification. This Acidification produces the hydronium ions as more acidic nature implies higher concentrations of hydrogen ions.
Carbon dioxide is a gas that readily dissolves in water to give Carbonic Acid , bicarbonate ions and carbonate ions , all of which are acidic in nature. This lowers the pH of the ocean making the waters more acidic. Therefore the acidity of oceans is largely dependent on carbon compounds and the amount of Carbon dioxide.
The reaction of Carbon dioxide with water to give carbonic acid :
CO2 + H2O → H2CO3

The unknown alcohol = 2-propanol
<h3>Further explanation</h3>
Given
volume = 50 ml
mass = 39.4 g
Required
The unknown alcohol
Solution
Density of sample :
= mass : volume
= 39.4 g : 50 ml
= 0.788 g/ml
The unknown alcohol at room temperature = liquid, so the unknown alcohol is 2-propanol because it has temperature range between -90 to 82 for liquid and the density = 0.788 g/ml
A model of an atom is important in understanding chemistry and in explaining the behavior of matter because it is the components of the atoms that gave rise to the different properties exhibited by the elements especially the electrons. From the model of the atom, we can predict the how would the elements or molecules behave or interact with each other. Also, it is the from the smallest unit of matter that we can actually see what is going on with the substance undergoing a particular process. You would see the arrangement of the subatomic particles and its effect on the overall structure.
