How do chaetoceros contribute to global atmospheric oxygen and carbon dioxide levels?

1 answer:

3 0

Chaetoceros is planktonic diatoms and known to be the largest genus with 400 described species. It has a cell wall made up of silica containing long thin spins. These spines connect the cell walls together to form a colony of cells.

Due to its high rate of growth and high lipid concentration, they can be used as bio fuel. Colonies of chaetoceros act as an important food source inside the water and they are major contributor of carbon.

In north water, they contribute 91% of the total phytoplankton cells thus acting as an important producer in the area. This contributes to the production of oxygen in north water. Total phytoplankton contributes to half of the oxygen production of Earth.

In this way, chaetoceros contribute to global atmospheric oxygen and carbon dioxide levels.

The answer to question 2

Bad White [126]

Answer:

Explanation:

You will need a chemical equation with masses and molar masses, so let’s gather all the information in one place.

$M_{r}$ : 258.21 18.02

KAl(SO₄)₂·xH₂O ⟶ KAl(SO₄)₂ + xH₂O

Mass/g: 4.74 2.16

Step 1. Calculate the mass of the KAl(SO₄)₂.

Mass = 4.74 g – 2.16 g = 2.58 g.

Step 2. Calculate the moles of each product.

$\text{Moles of KAl(SO}_{4})_{2} = \text{2.58 g} \times \frac{\text{1 mol} }{\text{258.21 g}} = 9.992 \times 10^{-3} \text{ mol}$

$\text{Moles of H}_{2}\text{O} = \text{2.16 g} \times \frac{\text{1 mol} }{\text{18.02 g}} = \text{ 0.1200 mol}$

Step 3. Calculate the molar ratio of the two products.

$\frac{\text{Moles of KAl(SO}_{4})_{2}}{\text{Moles of H}_{2}\text{O}} = \frac{ 9.992 \times 10^{-3} \text{ mol}}{\text{ 0.1200 mol} } = \frac{1 }{12.01} \approx \frac{ 1}{ 12}$

1 mol of KAl(SO₄)₂ combines with 12 mol H₂O, so x = 12.
