Answer:

The biological pump or the marine carbon pump is the title for multiple processes leading to separation of carbon from multiple sources of water. Biological pumping is partially responsible for the cycling of organic matter. This process can lead to loss of contact between carbon and the atmosphere for thousands of years.

Hope this helped!

Answer:

<h2>18 {cm}^{3}</h2>

Explanation:

<em><u>In</u></em><em><u> </u></em><em><u>first</u></em><em><u> </u></em><em><u>picture</u></em><em><u>,</u></em>

When rock was not in the cylinder,

Volume of water

=  {18cm}^{3}

<em><u>In</u></em><em><u> </u></em><em><u>second</u></em><em><u> </u></em><em><u>picture</u></em><em><u>,</u></em><em><u> </u></em>

When rock is in the cylinder,

Volume of water

=  {36cm}^{3}

<em><u>Hence</u></em><em><u>,</u></em>

Volume of rock

= 36 {cm}^{3}  -  {18cm}^{3}

= 18 {cm}^{3} (ans)

If a pure compound is distilled, the head temperature will be____compared to the pot temperature. If however, an impurity is pre
shutvik [7]

Answer:

If a pure compound is distilled, the temperature of the head will be compared to the temperature of the pot. However, if there is an impurity present that strongly interacts with the molecules of the liquid, then the temperature must be increased to increase the vapor pressure of the liquid, eventually to atmospheric pressure, allowing the liquid to boil. Therefore, at the boiling point, the temperature of the pot will be higher than the temperature of the head.

Explanation:

when temperatures increase, pressures also do so, thus reaching boiling points where liquid states become gaseous.

30.5 g of sodium metal reacts with chlorine gas to produce sodium chloride. How much (in grams) chlorine gas must react with thi
Lena [83]

Answer:

Mass of chlorine = 47.22 g

Explanation:

Given data:

Mass of sodium = 30.5 g

Mass of chlorine= ?

Solution:

Chemical equation:

 2Na + Cl₂      →      2NaCl  

Number of moles of Na:

Number of moles = mass/molar mass

Number of moles = 30.5g/ 23 g/mol

Number of moles = 1.33 mol

Now we will compare the moles of Cl ₂ with Na from balance chemical equation.

                    Na            :              Cl ₂

                     2              :               1

                     1.33          :            1/2×1.33 = 0.665 mol

Mass of chlorine gas:

Mass = number of moles × molar mass

Mass = 0.665 mol × 71 g/mol

Mass = 47.22 g
