What does the abyssopelagic gets its energy and nutrients from?

Chemistry
1 answer:
uysha [10]3 years ago
8 0

Answer:

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. "Abyss" ... This region also contains a much higher concentration of nutrient salts, like ... Many animals also move very slowly to conserve energy. Their reproduction rates are also very slow, to decrease competition and conserve energy.

Explanation:

Rather than relying on producers to form the base of the food pyramid, organisms living in the abyssal zone must feed on the dead organic detritus that falls from oceanic layers above. ... For example, many of these organisms convert hydrogen sulfide to sulfate to produce chemical energy.

Define a salt bridge. Define a salt bridge. A pathway between the cathode and anode in which ions are oxidized. A pathway, compo
ycow [4]

Answer:

A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.

Explanation:

Salt bridge is a link between oxidation half and reduction half of a galvanic cell.

Functions of salt bridge are:

Maintaining electrical neutrality

Preventing cell from reaching equilibrium

For creating salt bridge, a U shaped glass tube is filled with an inert electrolyte. Electrolytes used in the salt bridge generally do not reacts with the cell chemicals.

Cations and anions of the electrolytes have same ionic conductivity and hence, migrate with the same speed.

Most commonly potassium chloride, sodium chloride and potassium nitrate are used as an electrolyte in salt bridge.

Electrolyte are generally mixed with agar agar to prevent mixing of chemicals in the two half cells.

Urea (CH4N2O) is a common fertilizer that can be synthesized by the reaction of ammonia (NH3) with carbon dioxide as follows: 2N
Montano1993 [528]

The question is incomplete, here is the complete question:

Urea (CH₄N₂O) is a common fertilizer that can be synthesized by the reaction of ammonia (NH₃) with carbon dioxide as follows: 2NH₃(aq) + CO₂(aq) → CH₄N₂O(aq) + H₂O(l) In an industrial synthesis of urea, a chemist combines 135.9 kg of ammonia with 211.4 kg of carbon dioxide and obtains 178.0 kg of urea.

Determine the limiting reactant. (express your answer as a chemical formula)

<u>Answer:</u> The limiting reactant is ammonia (NH_3)

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}     .....(1)

  • <u>For ammonia:</u>

Given mass of ammonia = 135.9 kg = 135900 g    (Conversion factor:  1 kg = 1000 g)

Molar mass of ammonia = 17 g/mol

Putting values in equation 1, we get:

\text{Moles of ammonia}=\frac{135900g}{17g/mol}=7994.12mol

  • <u>For carbon dioxide gas:</u>

Given mass of carbon dioxide gas = 211.4 kg = 211400 g

Molar mass of carbon dioxide gas = 44 g/mol

Putting values in equation 1, we get:

\text{Moles of carbon dioxide gas}=\frac{211400g}{44g/mol}=4804.54mol

The given chemical reaction follows:

2NH_3(aq.)+CO_2(aq,)\rightarrow CH_4N_2O(aq.)+H_2O(l)

By Stoichiometry of the reaction:

2 moles of ammonia reacts with 1 mole of carbon dioxide

So, 7994.12 moles of ammonia will react with = \frac{1}{2}\times 7994.12=3997.06mol of carbon dioxide

As, given amount of carbon dioxide is more than the required amount. So, it is considered as an excess reagent.

Thus, ammonia is considered as a limiting reagent because it limits the formation of product.

Hence, the limiting reactant is ammonia (NH_3)
