What key assumption of Bohr’s model would a Solar S y stem model of the atom violate? What was the theoretical basis for this as
Art [367]

Answer:

See explanation

Explanation:

The solar system consists of the sun at the core surrounded by all the planets in their proper order. Similarly, the Bohr model of the atom upholds Rutherford's planetary model in which the atom was said to have a positive core surrounded by electrons moving in orbits just as the planets orbit round the sun.

The difference between the two models is that electrons are able to move from one energy level to another. This assumption violates the principles of the solar system because the position of the planets are fixed in their orbits.

The theoretical basis behind this assumption is that each spectral line is produced by the transition of electrons from one energy level to another.

Which describes the correct number and types of atoms in this molecular structure?
Andrews [41]

Answer: Option (1) is the correct answer.

Explanation:

The molecular structure is as follows.

           CH_{3}-CO-CH_{2}-CO-CH_{3}

This compound contains carbon (C) atoms, hydrogen (H) atoms, oxygen (O) atoms.

Or, the chemical formula of this compound is C_{5}H_{8}O_{2}.

Thus, we can conclude that there are five carbon atoms, eight hydrogen atoms and two oxygen atoms.

Which term describes the difference in electrical charge across a membrane?
Dmitry_Shevchenko [17]

Answer:

Resting potential

Explanation:

The resting potential is the term used to the describe the difference in electrical charge across a membrane. Ion is solution are capable of carrying a charge so their presence in biological systems is of interest. Two factors affect the resting potential:

  • the concentration gradients of the ions in solution across the membrane
  • the permeability of the said membrane to the ions mentioned above
