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

This is referred to as: spontaneous recovery

Spontaneous recovery is a theory of learning and memory which involves unexpected and recurrence of a conditioned response after a period of reduced response or delay. Spontaneous recovery is associated with classical conditioning and operant conditioning. Extinction will happen quickly after a spontaneous recovery, if the conditioned and unconditioned stimulus is not connected.

lesantik [10]

Answer:

a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.

b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.

c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.
