Elaborate on the nuclear model of the atom. A. The nuclear model describes the atom as protons and neutrons distributed throughout a sea of electrons.

B. The nuclear model describes the atom as electrons uniformly scattered in a positive cloud of protons.

C. The nuclear model describes the atom as a small, negative center enveloped by a cloud of positive particles.

D. The nuclear model describes the atom as a dense, positive nucleus surrounded by a cloud of negative electrons.

D

Explanation:

The nuclear model of the atom was proposed by Ernest Rutherford.

In his submission, the atom consists of a dense positive nucleus with electrons moving round this nucleus as planets move round the sun. He likened his model to the solar system. The nucleus is at the center of this system just as the sun is at the center of the solar system.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
