In what way do the oceans and the forests perform a similar function in the carbon cycle, under normal conditions?.
ikadub [295]

Both take carbon dioxide out of the atmosphere.

The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.

Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.

Can someone please help me please
GaryK [48]

Liquids have more kinetic energy in their particles compared to solids. this allows the particles to move more freely, hence why they are fluids


Liquids diffuse from a region of high concentration to a region of low concentration, until equilibrium is reached


When heat is applied the particles gain more kinetic energy so they now have enough energy to overcome the bonds holding them in the liquid. this means they can evaporate off

Given your results of Part III, predict the solubility of the following mixtures. Explain your answers. a) Methanol (CH,OH) in w
Setler79 [48]

Answer:

( a ) soluble

( b ) soluble

( c ) insoluble

Explanation:

Solubility is determined by the principle ,  "like dissolves like" .

i.e. ,<u> if a compound is polar then it will dissolve in a polar compound only , </u>and

<u>if a compound is non - polar then it will dissolve in a non - polar compound only .</u>

Hence , from the question ,

( a )

Methanol and water as we know are both polar species , hence , according to the principle - soluble .

( b )

Hexane and cyclohexane

Both the species are polar species , hence , according to the principle - soluble .

( c )

Hexane and water

In this case ,

Hexane , is non polar and water is polar , hence , the mixture will be non soluble .
