For the reaction: PCl5(g) ⇌ PCl3(g) + Cl2(g) at 600.0 K, the equilibrium constant is 11.5. Suppose that 1.500 g of PCl5 (MW=208.

22 g/mol) is placed in an evacuated 500.0 mL bulb, which is then heated to 600.0 K. What is the total pressure (in atm) in the bulb at equilibrium?

Answer:

1.418688 atm

Explanation:

(a)  Moles of PCl5 = mass / molar mass

                      =1.5 g / 208.22 g/mol

                     = 0.0072 moles

Also given,

T = 600 K

V = 0.500 L

Pressure of PCl5, P = nRT / V

                             = 0.0072 mol×0.0821 L-atm / (mol.K)×600 K / 0.500 L

                             = 0.709344 atm

(b)  PCl5(g) ⇄ PCl3(g) + Cl2(g)

Initial               0.965         0               0

Change               -x            +x             +x

Equilibrium (0.709344 -x)         x               x

K_p = 11.5 = x×x / (0.965 -x)

solving, we get x = 0.67027

So partial pressure of PCl5 at equilibrium = 0.709344 - 0.67027 = 0.039074 atm

(c)   Partial pressure of PCl3 = Cl2 = 0.709344 atm

So total pressure = 0.709344+0.039074+ 0.67027= 1.418688 atm

What are the two factors that affect ionic bond formation? Additionally, can you describe the trends of one of these factors in
solniwko [45]

Answer:

Ionization energy of the metal and electron affinity of the nonmetal

Explanation:

An ionic bond is formed when a metal transfers electrons to a nonmetal.

M· + A ⟶ M⁺ + ·A⁻

The two main factors affecting this process are the

  • Ionization energy of the metal
  • Electron affinity of the nonmetal

1. Ionization energy

The lower the ionization energy of the metal, the more likely it is able to donate an electron.

2. Electron affinity

The higher the electron affinity of the nonmetal, the more likely it is to accept an electron,

3. Periodic trends

(a) Ionization Energy

Ionization energy increases from bottom to top and from left to right in the Periodic Table.

Thus, the atoms with the lowest ionization energy are in the lower left corner of the Periodic Table.

(b) Electron affinity

Electron affinity increases from bottom to top and from left to right in the Periodic Table.

Thus, the atoms with the highest electron affinity are in the upper right corner of the Periodic Table.

Which of these are equal to 6.02 x 1023 particles? 12.01 g carbon (C) 44.08 g of silicon dioxide (SiO2) 16 g of ozone (O3) 16.04
ki77a [65]
It is known that 1 mol of a substance is equal to 6.02x10^3 particles. This is called the Avogadro's number. From this knowledge, we convert the mass of the substances given above into units of moles by using the molar mass.

12.01 g C ( 1 mol / <span>12.01 g) = 1 mol 
44.08 g SiO2 ( </span>1 mol / <span>60.08 g ) = 0.73 mol
16 g of O3 (</span>1 mol / <span>48 g) = 0.33 mol
16.04 g CH4 (</span>1 mol / <span>16.05 g ) = 0.99 mol

So, the answers are carbon and </span><span>carbon tetrahydride</span>.

UGH NO ONE IS HELPING MEEE
Bogdan [553]

Answer:

Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless ramp is equal to the gravitational potential energy of the block at the top of the ramp. This value is proportional to the square of the block’s velocity at the bottom of the ramp. Therefore, the block’s final velocity depends on the height of the ramp but not the steepness

of the ramp
