The disaccharide sucrose.
Sucrose molecules associate with water because they are polar, with both positive and negative charges. Water molecules are also polar, so they are attracted to the charged regions on the sucrose molecules, forming hydrogen bonds. This interaction between sucrose and water allows sucrose to dissolve in water.
You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

Sucrose is a disaccharide composed of glucose and fructose. A sucrase will hydrolyze sucrose into both constitute parts. You will be left with glucose and fructose, but you cannot directly transform sucrose to glucose.
There are 1.81 x 10^24 sucrose molecules in 3.0 moles of sucrose.
The disaccharide sucrose.
Sucrose molecules associate with water because they are polar, with both positive and negative charges. Water molecules are also polar, so they are attracted to the charged regions on the sucrose molecules, forming hydrogen bonds. This interaction between sucrose and water allows sucrose to dissolve in water.
Sucrose can affect diffusion as it can slow down the movement of molecules across a membrane. This is because sucrose is a larger molecule compared to other substances commonly involved in diffusion. It can create a barrier that hinders the rate of diffusion.
The specific type of chemical bond that connects the glucose and fructose molecules in sucrose is called a glycosidic linkage.

When sucrose dissolves in water, the sucrose molecules are surrounded by water molecules which break the bonds in the sucrose molecule, separating it into its constituent glucose and fructose molecules. The resulting solution is a homogeneous mixture known as a sugar solution.
No they are not.
Yes, the energy generated by the movement of molecules is called heat energy. This movement causes the molecules to vibrate and collide, which produces thermal energy that we perceive as heat.
The correct order by size of the molecules listed would be protein > sucrose > glucose > water. Proteins are the largest molecules, followed by sucrose (a disaccharide), glucose (a monosaccharide), and then water.
Yes, sucrose molecules are larger than glucose molecules. Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule, while glucose is a monosaccharide. This difference in structure accounts for the difference in size between the two molecules.
