As you move down a column what happens to the ionic radius?

Vera_Pavlovna [14]

The ionic radius increases.

Each time you move down to the next Period, you are adding an extra shell of electrons.

Each shell is further from the nucleus than the one before it, so the .

The image below illustrates the increase in ionic radius as you go down a Group.

A sample of gaseous PCl₅ was introduced into an evacuated flask so that the pressure of pure PCl₅ would be 0.50 atm at 523 K. Ho

Lera25 [3.4K]

Answer:

Kp = 0.2215

Kc = 0.0052

Explanation:

Step 1: The balanced equation

PCl5(g) → PCl3(g) + Cl2(g)

Step 2: given data

Initial pressure PCl5 = 0.50 atm

Temperature = 523 Kelvin

The actual pressure in the flask was found to be 0.74 atm.

Step 3: Calculate the pressure after the decomposition

Pressure of PCl5 after decomposition = 0.5 - X

Since the equation has a ratio 1:1 the pressure after the decomposition of PCl3 and Cl2 is X

Step 4: Calculate total pressure at equilibrium

0.74 atm = 0.5 atm - X + 2X

X = 0.74 - 0.5 = 0.24 atm

Step 5: Calculate Kp

Kp = P(PCl3)* P(Cl2) / P(PCl5)

Kp = 0.24² / 0.26 = 0.2215

Step 6: Calculate Kc

The ideal gas wet: P*V = nRT

with P= the pressure of the gas in atm

with V= the volume of the gas in L

with n= the number of moles

with R= the gas constant in L*atm/mol*K

T = the temperature in Kelvin

P= nRT/V

Kp= Kc*(RT)^Δn

Kc=Kp/(RT)^Δn

Kc= 0.2215 / (0.08206*523)^1

Kc= 0.0052

State, in terms of subatomic particles, how an atom of C-13 is different from an atom of C-12

mariarad [96]

C-12 and C-13 are isotopes of the element carbon. Since they are both of the same element, they have the same number of protons. The number that follows the C indicates the number of neutrons. Isotopes are variations of the element with different number of neutrons. C-12 shows that that variation of carbon has 6 protons and 6 neutrons for a total mass of 12. C-13 shows that it has 6 protons but 7 neutrons for a total mass of 13
