Answer:

D. 0.063 mol

Explanation:

We can calculate the number of moles by using the definition of molarity:

Molarity = moles / liters

As we are given both the molarity and the volume:

0.05 M = moles / 1.25 L

We can calculate the number of moles:

moles = 0.05 M * 1.25 L

moles = 0.063 mol

Thus the answer is option D.

Answer:

B. the resonance hybrid of all structures

Explanation:

The idea of resonance is used to explain bonding in compounds where a single structure does not fully account for all the bonding interactions in a molecule.

A number of equivalent structures are then used to show the nature of bonding in such a molecule. Such structures are called resonance structures or canonical structures. None of these structures individually offer a holistic explanation to the bonding interactions in the molecule under study.

However, a hybrid of all the canonical structures does explain the nature of bonding in the molecule.
