In 1808, John Dalton proposed a series of statements regarding the atom that became known as Dalton's postulates or Dalton's ato

mic theory. Since Dalton's original proposal, some of the statements have been updated or changed due to new discoveries. Which of the statements was not a part of Dalton's original atomic theory? Matter is comprised of small particles called atoms. All four statements are part of Dalton's original atomic theory. Different elements have atoms of different masses and properties. Atoms of the same element have the same size, mass, and structure. Atoms cannot be created or destroyed in a chemical reaction.

Answer:

The all 4 the given statements are part of Dalton's atomic theory.

Explanation:

Dalton's postulates or Dalton's atomic theory:

  • Matter is made up of small particles termed as atom.
  • Atoms are indivisible particle.
  • Atoms of different element have different masses and properties.
  • Atoms of the same element have the identical size, mass, and structure.
  • During chemical reaction, rearrangement of atoms takes place.
  • Atoms of different different combines together to form new compounds in simple whole number ratio.

The equilibrium constant for the chemical equation N2(g) + 3H2(g) ⇌ 2NH3(g) and Kp=0.174 at 243°C. Calculate the value of Kc for
Mashcka [7]

Answer:

The Kc of this reaction is 311.97

Explanation:

Step 1: Data given

Kp = 0.174

Temperature = 243 °C

Step 2: The balanced equation

N2(g) + 3H2(g) ⇌ 2NH3(g)

Step 3: Calculate Kc

Kp = Kc *(RT)^Δn

⇒ with Kp = 0.174

⇒ with Kc = TO BE DETERMINED

⇒ with R = the gas constant = 0.08206 Latm/Kmol

⇒ with T = the temperature = 243 °C = 516 K

⇒ with Δn = number of moles products - moles reactants  2 – (1 + 3) = -2

0.174 = Kc (0.08206*516)^-2

Kc = 311.97

The Kc of this reaction is 311.97
