When glaciers are growing larger, the concentration of the heavier oxygen isotope in sea water increases?

Chemistry

Dmitry_Shevchenko [17]3 years ago

Answer: TRUE

Explanation: Oxygen has two isotopes namely, ¹⁶O (being the lighter oxygen) and ¹⁸O (being the heavier oxygen). Both this isotopes plays a significant role.

The water-ice that accumulates at the glaciated region are derived from the seas and oceans. The ocean and sea water when heated, gets vaporized and rises up, being rich in ¹⁶O, whereas the ¹⁸O, being the heavier isotope does not get vaporize and so it remains in the oceans.

This lighter oxygen isotopes ¹⁶O are then carried to the atmosphere which subsequently falls back as snow in the glacial covered region and consecutively forms ice undergoing compaction.

This, is the reason why ¹⁶O are rich in the glaciated region, whereas the ocean waters are rich in ¹⁸O.

Thus, the above given statement is true, i.e when glaciers become large in size and quantity, then the concentration of heavier oxygen isotope also increases in the ocean and sea water.

Answer : Yes, The heavier oxygen isotope in sea water is increasing as the result of growing of larger glaciers.

The global warming of the climate which is also called as global warming is helping to increase the isotopic oxygen in the ocean and sea waters. When glaciers are growing they have comparatively less isotopic oxygen but this proportion changes with the temperature.

What is the final volume?
zaharov [31]

Answer:

Option A. 9.4 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 8 L

Initial temperature (T₁) = 293 K

Final temperature (T₂) = 343 K

Final volume (V₂) =?

V₁ / T₁ = V₂ / T₂

8 / 293 = V₂ / 343

Cross multiply

293 × V₂ = 8 × 343

293 × V₂ = 2744

Divide both side by 293

V₂ = 2744 / 293

V₂ = 9.4 L

Therefore, the final volume of the gas is 9.4 L

Explain in words or using your diagrams how beryllium atoms would react with fluorine atoms.
Marysya12 [62]

Explanation:

To delineate the the nature of the bonds that would be formed between the two elements, let us first write the electronic configuration of the two species;

  Be  = 2, 2

  F  = 2, 7

 Beryllium is a metal with two valence electrons whereas fluorine is a halogen with seven valence electrons.

When Be loses two electrons it becomes isoelectronic with He;

                 Be →  Be²⁺ + 2e⁻  

Also, when fluorine gains  an electron, it becomes isoelectronic with Ne;

               F  + e⁻ →  F⁻

This loss and gain of electrons between the two elements creates an electrostatic attraction them and they enter into an electrovalent bond.

      Hence;

           Be²⁺  + 2F⁻ → BeF₂

Photosynthesis is The process that uses sunlight energy to convert water, and carbon dioxide into high energy glucose, and oxygen.




Chloroplast is This organelle of a cell, is where chlorophyll is found. The organelle most involved in photosynthesis.








Hope that helps!!! :)



Chlorophyll is a green pigment present in all plants, that absorbs light to provide energy for photosynthesis.




Energy is the ability to do work, That can produce physical changes within living, and non-living systems.

how many molecule of carbon dioxide are needed to react with excess iron oxide to produce 11.6 g of iron
lesya692 [45]

Answer:

0.16 moles of Carbon

Explanation:

The balanced reaction equation:

2Fe_{2}O_{3} + 3C → 4Fe + 3CO_{2}↑

The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)

i.e 3 moles of C produces 4 moles of Fe.

If 1 mole of Fe - 55.8g of Fe

? moles - 11.6g of Fe

= \frac{11.6}{55.8} = 0.208 moles

But 3 moles of C - 4 moles of Fe

? moles of C - 0.208 moles of Fe

= \frac{3 *0.208}{4} = 0.16 moles of carbon.

I hope this explanation was clear and useful.
