Astudent wants to increase the maximum amount of sugar that can dissolve in water. she crushes the sugar and then stirs it into the water. does this work?

Explanation:

When the student crushes sugar there there occurs an increase in the number of molecules or particles of sugar. This means that now more number of sugar particles (solute) are able to interact with water (solvent).

Therefore, there will be more number of collisions taking place between the solute and solvent molecules.

As a result, sugar will dissolve readily into water as there is an increase in interaction between solute and solvent particles.

Thus, we can conclude that when he crushes the sugar and then stirs it into the water then it will work as this leads to more interaction or collisions between the solute and solvent particles.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
