Answer:

speed is the speed with which an object travels

Explanation:

for physics The average speed of an object is defined as the distance traveled by an object divided by the elapsed time. Speed is a vector quantity and the average speed can be defined as the displacement divided by time. in the same way the speed helps to calculate the travel time, since the more speed the less time is made.

The partial pressure of N2 in the air is 593 mm Hg at 1 atm. What is the partial pressure of N2 in a bubble of air a scuba diver

Evgen [1.6K]

Answer: Partial pressure of $N_{2}$ at a depth of 132 ft below sea level is 2964 mm Hg.

Explanation:

It is known that 1 atm = 760 mm Hg.

Also, $P_{N_{2}} = x_{N_{2}}P$

where, $P_{N_{2}}$ = partial pressure of $N_{2}$

P = atmospheric pressure

$x_{N_{2}}$ = mole fraction of $N_{2}$

Putting the given values into the above formula as follows.

$P_{N_{2}} = x_{N_{2}}P$

$593 mm Hg = x_{N_{2}} \times 760 mm Hg$

$x_{N_{2}}$ = 0.780

Now, at a depth of 132 ft below the surface of the water where pressure is 5.0 atm. So, partial pressure of $N_{2}$ is as follows.

$P_{N_{2}} = x_{N_{2}}P$

= $0.78 \times 5 atm \times \frac{760 mm Hg}{1 atm}$

= 2964 mm Hg

Therefore, we can conclude that partial pressure of $N_{2}$ at a depth of 132 ft below sea level is 2964 mm Hg.

$Z= 1s^22s^22p^63s^23p^5$

<h3>What is an electronic configuration?</h3>

Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.

$x=1s^2$

$Y= 1s^22s^22p^63s^2$

$Z= 1s^22s^22p^63s^23p^5$

x= Period 1 and group18

Y=Element is in period 3 and Group 2

Z=Element is in period 3 and group 17.

X, Y & Z represents Helium, magnesium, and chlorine.
