How is it possible for carbon to move through the biotic parts of carbon cycle

andrey2020 [161]

Answer:

Explanation:

Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.

Match the following aqueous solutions with the appropriate letter from the column on the right. Assume complete dissociation of

Serhud [2]

Answer: 0.17 m $CH_3COONH_4$ : Highest freezing point

0.20 m $CoSO_4$ : Second lowest freezing point

0.18 m $MnSO_4$ : Third lowest freezing point

0.42 m ethylene glycol: Lowest freezing point

Explanation:

Depression in freezing point is a colligative property which depend upon the amount of the solute.

$\Delta T_f=i\times k_f\times m$

where,

$\Delta T_f$ = change in freezing point

i= vant hoff factor

$k_f$ = freezing point constant

m = molality

a) 0.17 m $CH_3COONH_4$

For electrolytes undergoing complete dissociation, vant hoff factor is equal to the number of ions it produce. Thus i =2 for $CH_3COONH_4$ , thus total concentration will be 0.34 m

b) 0.18 m $MnSO_4$

For electrolytes undergoing complete dissociation, vant hoff factor is equal to the number of ions it produce. Thus i = 2 for $MnSO_4$ , thus total concentration will be 0.36 m

c) 0.20 m $CoSO_4$

For electrolytes undergoing complete dissociation, vant hoff factor is equal to the number of ions it produce. Thus i = 2 for $CoSO_4$ , thus total concentration will be 0.40 m

d) 0.42 m ethylene glycol

For non electrolytes undergoing no dissociation, vant hoff factor is equal to 1 . Thus i = 1 for ethylene glycol, thus concentration will be 0.42 m

The more is the concentration, the highest will be depression in freezing point and thus lowest will be freezing point.

Explanation:

(1)

True

The winds are significant in the distribution of heat across the globe. There are global air circulations around the world such as the Hadley and polar cells that take heat from the hotter regions to the cooler regions. This is driven by high and low-pressure systems on earth that are influenced by the sun. Cooler air masses move from the high-pressure system and displace the warm winds in the low-pressure systems. This helps in maintaining a heat balance on earth.

(2)

False

The geosphere not only includes all the rocks on the surface of the earth but also the whole of the lithosphere ( or crust), which also includes all the landforms on earth. All the rocks and minerals in the interior of the earth are also part of the geosphere, including the process – such as the convection currents of the mantle- that helps in the shaping of the earth's surface.

(3)

In a storm, the heat from the hydrosphere which is transferred to the atmosphere via the heat of evaporation is what feeds the storm. Therefore these two spheres not only share distribution of heat energy but also water. When the storms dissipate the heat and its water from the clouds, the water flows back to the hydrosphere and the cycle continues.

(4)

True

The biosphere includes all the living and biotic components on earth. Therefore even the marine animals in the oceans are part of the biosphere. They are one aspect that signifies the interaction betwene the hydrosphere and the biosphere. These organisms draw oxygen, water and minerals from the hydrosphere which is important or life.

(5)

True

However, the atmosphere is not the only sphere that distributes heat across the globe. So does the hydrosphere. The ocean's currents are very significant with this regard just as are air currents, The warm surface currents from the equator distribute heat towards the poles while cooler deeper currents flow towards the equator from the poles – maintaining a heat balance on earth.

(6)

When a volcano erupts, gases -like sulfur dioxide and carbon dioxide- and pyroclasts from deep in the earth rocks (geosphere) are spewed into the atmosphere. This is an example of how these two spheres of the earth interact.
