Neko [114]
<h2>The required "options are (II), (III), and (IV)".</h2>

Explanation:

Postulates of Dalton's atomic theory which are scientifically accepted are:

  • Atoms are indestructible.
  • Compounds are combinations of different atoms.
  • A chemical reaction changes the way atoms are grouped together.

Postulates of Dalton's atomic theory which are not accepted scientifically are:

  • All atoms of the same elements are identical.

            The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.

lana [24]

Answer:

the equilibrium constant is 1.8 x 10⁻5 and strongly favor the reactants.

Explanation:

the chemical reaction provided for the two equation are the same but different direction i.e a reversible reaction. Assuming, the mass of reactants and product and temperature remain constant.

therefore, the equilibrium constant K, is 1.8 x 10⁻5. this is a very small value of K, thereby strongly favor the backward direction to form reactant.
