Transition metals have delocalized electrons called an "electron sea." What property does this allow?

Chemistry
1 answer:
RideAnS [48]3 years ago
7 0

Answer:

A conducting electricity

Explanation:

The "electron sea" allows the current to flow across the electrons. If the electrons were stuck in their positions, these metals would be better insulators than conductors because they couldn't spread (or <em>conduct) </em>the energy as electricity.

B, C, and D are all not things directly caused by the delocalized electrons.

Sodium is not a macromolecule hence it does not contain any calories.

<h3>Does sodium contain calories?</h3>

The term  calorie is a unit of energy. We often us the term to describe the amount of energy that is contained in each kind of food. The higher the calories, the greater the energy that the food contains.

Calories can only be contained by macromolecules such as proteins, carbohydrates, fats etc. Sodium is not a macromolecule hence it does not contain any calories at all hence the classmate is wrong.

What types of questions can be answered through science and what questions are beyond the boundaries of science? Be specific and
Anna [14]
The questions tha science can answer are those can be tested to try to find a definite answer.

For example, whether light is wave or particle is matter of science.

Questions that cannot have a definite answer are the field of religion or philosophy, and are out of the boundaries of science.

For example, does a criminal deserve the punishment of not seeing light? It is a moral question, which to be responded needs the intervention of philosophy and that could have different anwers at different times and in different societies.

What is the maximum number of moles of Al2O3 that can be produced by the reaction of .4 mol of Al with .4 mol of O2
Darya [45]

<u>Given:</u>

Moles of Al = 0.4

Moles of O2 = 0.4

<u>To determine:</u>

Moles of Al2O3 produced

<u>Explanation:</u>

4Al + 3O2 → 2Al2O3

Based on the reaction stoichiometry:

4 moles of Al produces 2 moles of Al2O3

Therefore, 0.4 moles of Al will produce:

0.4 moles Al * 2 moles Al2O3/4 moles Al = 0.2 moles Al2O3

Similarly;

3 moles O2 produces 2 moles Al2O3

0.4 moles of O2 will yield: 0.4 *2/3 = 0.267 moles

Thus Al will be the limiting reactant.

Ans: Maximum moles of Al2O3 = 0.2 moles
