The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0
devlian [24]

Answer:

volume  = 0.285 L

Explanation:

Henry constant is given as

Henry constant  =  \frac{C}{P}

Where C  is concentration

P is atmospheric pressure

Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm

when atmospheric pressure 4 atm

solubility = K_H\times P

              = 0.0007 \times 4 = 0.0028 M

In 5 litere blood , moles of N_2 = Molarity \times volume

                                                     = 0.0028 \times 5 = 0.014

At surface moles  = 0.0056 \times 5 = 0.0028

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of N_2 = 0.0112 \times 28 = 0.314 g

T = 37 + 273 = 310 K

VOLUME = \frac{nRT}{P}

= \frac{0.0112\times 0.0821\times 310}{1}

volume  = 0.285 L

Can anyone help me write hydroelectric essay
Assoli18 [71]

Answer:

A competitive firm’s marginal revenue always equals its average revenue and price. This is because the price remains constant over varying levels of output. In a monopoly, because the price changes as the quantity sold changes, marginal revenue diminishes with each additional unit and will always be equal to or less than average revenue. A conclusion is the last paragraph of your essay, or, if you’re writing a really long essay, you might need 2 or 3 paragraphs to conclude. A conclusion typically does one of two things—or, of course, it can do both: Summarizes the argument. Some instructors expect you not to say anything new in your Hydro-power is the energy harnessed from running water-streams, rivers or any other artificial or natural water flow. It is one of the oldest method of energy production. Even in the medieval period, people used to derive energy from water wheels. The contribution of hydel power in the world en­ergy production scenario is immense and ever-increasing.

Hydro-electricity now contributes nearly 7% of global electricity production when only 15.3 percent of the global exploitable hydro-electric potential is being used. Ever increasing awareness of ecology and social costs of hydro-plant construction failed to debar the increas­ing use of hydro-electricity.
