Answer:

topographic map only

Explanation:

Topographic maps show features on the earth's surface through symbols and labels in which there are colors that distinguish the different classes. The lines that connect points of features at equal elevations are called contours. An imaginary line is also drawn in which every point in it is of equal elevation with the others. A different contour represents a different elevation. The interval in contour is the difference in elevation between them.

If 1.00 mol of argon is placed in a 0.500- L container at 24.0 ∘C , what is the difference between the ideal pressure (as predic

swat32

The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is 2.08 atm.

<h3>What is the pressure?</h3>

In this problem, we are mandated to obtain the pressure both by the use of the ideal gas equation and then the use of the Van der Walls equation.

Using the idea gas equation;

PV = nRT

P = nRT/V

P = pressure

V = volume

n = number of moles

T = temperature

R = gas constant

P = 1 * 0.082 * (24 + 273)/0.5

P = 48.7 atm

Using the Van Der Wall equation:

P = RT/(V - b) - a /V^2

P = 0.082 * 297/(0.5 - 0.03219) - 1.345/(0.5)^2

P = 24.354/0.46781 - 1.345/ /0.25

P = 52 - 5.38

P = 46.62 atm

The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is; 48.7 atm - 46.62 atm = 2.08 atm

3. Crystalline structural unit of barium metal is a body-centered cubic cell. The edge length of the unit cell is 5.02x10-8 cm.

tiny-mole [99]

Answer:

The Avogadro's number is $N_A = 6.02289 *10^{23}$

Explanation:

From the question we are told that

The edge length is $L = 5.02 * 10^{-8} \ cm= \frac{5.02 * 10^{-8} }{100} = 5.02 * 10^{-10}$

The density of the metal is $\rho = 5.30\ g/cm^3 = 5.30 * \frac{g}{cm^3} * \frac{1*10^6}{1*10^3} = 5.30 *10^3kg/m^3$

The molar mass of Ba is $Z = 137.3 \ g/mol = \frac{137.3}{1000} = 0.1373 \ kg / mol$

Generally the volume of a unit cell is

$V = L^3$

substituting value

$V = [5.02 *10^{-10}]^3$

$V = 1.265*10^{-28}\ m^3$

From the question we are told that 68% of the unit cell is occupied by Ba atoms and that the structure is a metal which implies that the crystalline structure will be (BCC),

The volume of barium atom is

$V_a = \frac{V}{2} * 0.68$

substituting value

$V_a = \frac{ 1.265*10^{-28}}{2} * 0.68$

$V_a = 4.301 *10^{-29} \ m^3$

The Molar mass of barium is mathematically represented as

$Z = N_A V_a * \rho$

Where $N_A$ is the Avogadro's number

$N_A = \frac{ Z}{ V_a * \rho}$

substituting value

$N_A = \frac{ 0.1373}{ 4.301*10^{-29} * 5.3*10^{3}}$

$N_A = 6.02289 *10^{23}$

phosphorus-32 ahs a half-life of 14.0 days. Starting with 8.00 g of 32 P, how many grams will remain after 56.0 days

sertanlavr [38]

0.500 grams would be left after 56.0 days.

After 14 days=4.00 g
After 28 days=2.00 g
After 42 days=1.00 g
After 56 days=0.500 g

This is after four half lives.
