Use the Keq equation.. concentraion of products divided by concentration of reactants at equilibrium. (with coefficients as exponents, none in this case reaction is balanced)

Keq = [PCl5] / ([PCl3] [Cl2])

fill in given values and solve for [Cl2] using algebra. Im just going to sub in "c" for the unknown.

0.00094 = 0.44 / 0.33c
0.0003102c = 0.44
c = 1418.44 mol/L

Which of the following is not a part of the ideas john dalton proposed in his model
NNADVOKAT [17]

The following which is not a part of  Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

<h3>What is Dalton atomic theory?</h3>

Dalton has proposed his theory in three parts and each part stated that

The first portion of his theory asserts that all stuff is made up of indivisible atoms.

According to the second section of the theory, all atoms of a given element have the same mass and characteristics.

Compounds, according to the third section, are combinations of two or more different types of atoms.

Dalton has given three laws

  • Law of conservation of mass
  • Law of definite proportion
  • Law of multiple proportion

Thus, the following which is not a part of  Dalton atomic theory is the properties of atoms of the same elements can be different . Thus option B is correct.

calculate q for the following: 125.0 ml of 0.0500 m pb(no3)2 is mixed with 75.0 ml of 0.0200 m nacl at 25oc chegg
alexandr402 [8]

The value of Q for 125.0 ml of 0.0500 m Pb(NO3)2 is mixed with 75.0 ml of 0.0200 m NaCl at 25°C is 2.11 × 10^(-6).

Aa we know that, 125mL of 0.06M Pb(NO3)2 is mixed with 75.0 ml of 0.0200 m NaCl.

Given, T = 25°C.

<h3>Chemical equation:</h3>

Pb(NO3)2 + NaCl ---- NaNO3 + PbCl2

PbCl2 in aqueous solution split into following ions

PbCl2 ------ Pb(+2) + 2Cl-

Q = [Pb(+2)] [Cl-]^2

The Concentration of Pb(+2) ions and Cl- ions can be calculated as

[Pb(+2)] = 0.06 × 125/200

= 0.0375

[Cl-] = 0.02 × 75/200

= 0.0075

By substituting all the values, we get

[0.0375] [0.0075]^2

= 2.11 × 10^(-6).

Thus, we calculated that the value of Q for 125.0 ml of 0.0500 m Pb(NO3)2 is mixed with 75.0 ml of 0.0200 m NaCl at 25°C is 2.11 × 10^(-6).
