Why is ethyl alcohol a water-miscible solvent?
Ethyl alcohol (or ethanol) is water-miscible because it can form hydrogen bonds with water molecules. The hydroxyl (OH) group in ethanol is polar and can interact with the polar water molecules, allowing ethanol to mix easily with water. This property makes ethanol a versatile solvent for a wide range of substances.
Is the concentration of water molecules higher in pure water or in sugar water?
The concentration of water molecules is higher in pure water compared to sugar water. Sugar water has sugar molecules dissolved in it, which decreases the concentration of water molecules relative to pure water.
What are free water molecules?
Free water molecules refer to water molecules that are not bound to other substances or ions. These molecules are freely moving and not involved in chemical interactions or bonding with other molecules.
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state
What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
The polar nature of water allows it to dissolve?
a wide variety of substances, making it a versatile solvent in biological systems. The hydrogen bonding between water molecules contributes to its strong cohesive properties.

How many molecules of water H20 contain2.60x1023molecules of water?
2.60x10^23 water molecules contain 2.60x10^23 molecules of water.
Is the concentration of water molecules higher in pure water or in sugar water?
The concentration of water molecules is higher in pure water compared to sugar water. Sugar water has sugar molecules dissolved in it, which decreases the concentration of water molecules relative to pure water.
Why is water a versatile solvent?
Commonly describes as the "versatile solvent", water is a substance that can dissolve almost anything. Because of this, water in nature and in use is rarely pure, and may have some properties different from those in the laboratory. Salts such as sodium chloride dissolve in water by dissociating as each ion becomes surrounded (spherical shape) by the polar water molecules. This sphere of water molecules around each dissolved ion is called a hydration shell. Shielded by this shell of water molecules, the ions remain in solution because they are no longer affected by attractive forces from surrounding ions.
Is salt water made of 1 or more molecules?
It is made of water (H2O) molecules and salt (NaCl) molecules. So two different types of molecules.
What happens to the molecules of a solid such as a sugar cube when it dissolves water?
When a solid such as a sugar cube dissolves in water, the molecules of the sugar cube spread out and become surrounded by water molecules. The water molecules interact with the sugar molecules and weaken their bonds, causing the sugar molecules to separate and disperse throughout the water, resulting in a homogeneous mixture.
When water molecules stick to the molecules of other substance the molecules are displaying?
Adhesion is the ability of water molecules to stick to other molecules. Cohesion is the ability of water molecules sticking to one another.
Which of the following terms describes water molecules sticking to other water molecules?
The term that describes water molecules sticking to other water molecules is cohesion. This cohesive property is a result of hydrogen bonding between the water molecules.
Adjacent water molecules other names?
adjacent water molecules are also known as Polar Covalent Bonds.
What happens when water molecules when heat is added to water molecules?
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
Polar covalent molecules are likely to dissolve in water because they have partial positive and negative charges that can interact with water molecules through dipole-dipole interactions. Ionic molecules also dissolve in water as the positive and negative ions are attracted to the polar water molecules. Nonpolar covalent molecules do not dissolve well in water because they lack partial charges that can interact with water molecules.
