Answer 2

The acid-conjugate base pair : ( B ) NH₄⁺ and H₃O⁻

The chemical reaction is

NH₄ + H₂O --> NH₃ + H₃O

Acid-conjugate base pair

An acid-conjugate base pair is a pair that consists of two substances that are different from each other just by the presence or absence of a proton ( H⁺ ) it helps to determine the relative strengths of acids and bases.

Hence we can conclude that the acid-conjugate base pair : ( B ) NH₄⁺ and H₃O⁻.

Which statement accurately represents the arrangement of electrons in Bohr’s atomic model? -Electrons move around the nucleus in fixed orbits of equal levels of energy. -Electrons move around the nucleus in fixed orbits of increasing levels of energy. -Electrons move randomly in the relatively large space surrounding the nucleus. -Electrons vibrate in fixed locations around the nucleus.

Answers

Answer:

electrons move around the nucleus in fixed orbits of equal amounts of energy

Explanation:

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option B.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

According to Bohr’s atomic model,  electrons move around the nucleus in fixed orbits of increasing levels of energy.

Therefore, the correct option is option B that is electrons move around the nucleus in fixed orbits of increasing levels of energy.
