Answer:
a. Are miscible because each can hydrogen bond with the other.
Explanation:
Both ethanol and water are miscible. The reason why they can both mix freely is due to the hydrogen bonds that will form between their molecular structure.
Hydrogen bonds are special dipole-dipole attraction between polar molecules in which hydrogen atoms are directly joined to an electronegative atom.
Ethanol has an hydroxyl group which will bond to form an intermolecular bond with the oxygen and hydrogen on the water molecule. This attraction makes them miscible.

Instrumental methods of analysis rely on machines.The visualization of single molecules, single biological cells, biological tissues and nanomaterials is very important and attractive approach in analytical science.
There are several different types of instrumental analysis. Some are suitable for detecting and identifying elements, while others are better suited to compounds. In general, instrumental methods of analysis are:
-Fast
-Accurate (they reliably identify elements and compounds)
-Sensitive (they can detect very small amounts of a substance in a small amount of sample)
The new volume V₂ is 5.4L
The new volume is calculated using Boyle's law formula
That is P₁V₁=P₂V₂
where,
p₁ = 852 torr
V₁ = 27.0
P₂ = 4260 torr
V₂=?
Make V₂ the subject of the formula by diving into both sides of the equation by P₂
V₂ = P₁V₁/P₂
⇒ 852 *
V₂ is, therefore, = 5.4 L
