Answer:
The answer to the question is option <u>D</u>
Answer:
<u>True</u>, some molecules have the same molecular formula as their empirical formula.
Explanation:
The empirical formula of many compounds may be the same. Formaldehyde, for example, has the chemical formula CH2O, which is equal to the empirical formula of glucose. Each molecule of formaldehyde has one carbon atom, two hydrogen atoms, and one oxygen atom.
The lowest point of a wave is called trough.
Answer:

Explanation:
Hello,
In this case, the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:

In this case, the solute is the KCl (potassium chloride) and the solution is made up of both water and KCl. Moreover, since during this type of dissolution processes, the volume of the solution is not significantly affected by the addition of the solute, the resulting molarity is:

Best regards.
