The gas co2 is diffusin at steady state through a tube 20 cm long having a diameter of 1 cm and containing n2 at 350 k . the tot

Marrrta [24]

The value is J = 1.71*10^-6 kmol/m^2.s

According to the given conditions we get,

The length the tube l= 0.20m

The diameter of the tube d= 0.01m

The total pressure inside the tube P= 101.32kPa

The partial pressure of CO2 at the first end is

P1= 456mm Hg = 60794.832 Pa

The partial pressure of CO2 at the other end is

P2= 76mm Hg = 10132.472 Pa

The temperature is T = 298 K

The diffusion coefficient D= 1.67* 10^-5 m^2/s

Generally the molar flux of CO2 is mathematically represented as

J= D{p1-p2} / R.T

Here R is the gas constant with value R= 8.314 j/kmol

So we get J= 1.71 * 10^-3 mol/m^2.sec

I am confused on how to do this? please help!

IceJOKER [234]

You would take random numbers preferable smaller ones such as -1,0,1,2
You would put those in the place of x
Then you would square the value of x. After that you subtract 4. Whatever you come out with is your y value. Then you put the x value on the x axis and from that point count up or down to the number you need on the y axis. Together that would be your point

If 45% of a number n is 225 what is 75% of n

Tpy6a [65]

75% of n is 375.

Step-by-step explanation:

Given,

45% of a number n = 225

We will find n first.

$\frac{45}{100}n=225\\0.45n=225$

Dividing both sides by 0.45

$\frac{0.45n}{0.45}=\frac{225}{0.45}\\n=500$

Now we have to find 75% of n.

75% of n = $\frac{75}{100}*500=75*5$

75% of n = 375

75% of n is 375.

What is 7.8 × 105 m/h in kilometers per day? A. 3.24 × 1010 km/day B. 3.24 × 108 km/day C. 1.872 × 106 km/day D. 1.872 × 104 km/

damaskus [11]

The comparison may be done by the dimensional analysis and the proper conversion factor. That is,
(7.8 x 10^5 m/h) x (1 km / 1000 m) x (24 h / 1 day) = 18720 km / day
The scientific notation of the answer is 1.872 x 10^4 km/day. Thus, the answer is letter D.
