Enthalpy of solution describes the net change in heat when a solute is dissolved in a solvent. Specifically, the standard enthalpy of solution is the heat change when one mole of solute is completely dissolved in a solvent to form a solution concentration of 1 mol per dm3 under standard conditions.
The net change in heat can be broken down into the sum of two heats. First, the solute crystals must break from their lattice. This is known as the lattice enthalpy and its reversal is typically endothermic. Second, the ions are solvated (or hydrated in the case of aqueous solutions), which is typically an exothermic step. Depending on the magnitude of each of these factors, the sum can lead to a positive or negative enthalpy of solution.

What does the negative sign on the value of an enthalpy of formation indicate?
A negative enthalpy of formation indicates that energy is evolved.
What does no solution mean in math?
it means no solution. no answer. cant be answered
Does the solution is the empty set mean there is no solution?
Yes, empty set means null which is no solution.
What is the solution of 7x-53 9x?
If you mean: 7x-53 = 9x Then the solution is: x = -26.5
What does it mean to be a solution to an equation?
A solution to an equation is a set of values for the variables in the equation which make it true.

How can the enthalpy change be determined for a reaction in an aqueous solution?
Utilizing a thermometer to measure the temperature change of the solution can be used (along with the mass of the reactant(s)) to determine the enthalpy change for an aqueous reaction, as long as the reaction is carried out in a calorimeter or similar apparatus so that no external heat is added or removed from the system.
What is the enthalpy of HDPE?
enthalpy LDPE
What is the heat of solution for sodium chloride in joules assume that the specific heat capacity of the system is the same as that for water?
The standard enthalpy for the change in solution is: +3,87 kJ/mol at 25 0C
What is the difference between enthalpy change and enthalpy change per mole?
Enthalpy is the energy absorbed or lost from a reaction, but enthalpy change per mole is the amount of energy lost per mole, so in order to get the overall enthalpy from the change per mole, you must multiply that value by the amount of moles used in the reaction.
How do you calculate the boiling point of water-ethylene glycol mixture?
