Negative heat of solution means the process if exothermic. More bonds and/or stronger bonds were made compared to the amount of bonds broken. Positive heat oof solution is the opposite, so it is endothermic and etc.

When a certain solid dissolves in water the solution becomes cool Is ΔHsoln for this solute positive or negative?
Positive, because as the solution forms, heat is absorbed. This answer was correct on WileyPlus
What does it mean when delta H is a negative number?
it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.
What is the heat solution of calcium chloride?
The heat of solution for CaCl2 is -176,2 cal/g.
What is the best way to make a supersaturated solution?
Heat the solution
Why lithium has exothermic heat of solution whereas chlorides of sodium have endothermic heat of solution?
lithium have low ionisation energy.
What is the term for Heat taken or released in a dissolving process?
I suppose that these are synonyms.
What geometric mean of -2 and 8?
No solution. A negative number is not allowed.
What does the word drawback mean?
A negative result of a option or solution you have in a given situation.
When a certain solid dissolves in water the solution becomes cool Is ΔHsoln for this solute positive or negative?
Positive, because as the solution forms, heat is absorbed. This answer was correct on WileyPlus
Why do you heat the sodium sulfate solution?
It is not mandatory to heat this solution.
What does it mean when delta H is a negative number?
it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.
What is the heat solution of calcium chloride?
The heat of solution for CaCl2 is -176,2 cal/g.
When heat flows into a system its value is When heat flows out of a system its value is negative?
Heat is energy and cannot be negative, If you are talking about heat flow then if you define outflow to be negative then inflow is positive.
What is downward heat flow?
negative heat
What does enthalpy of solution mean?
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 is the heat of solution for lithium chloride?
- 37.1 kj/mol is the heat of solution for lithium chloride.
What does principal root mean?
A principal root is the unique solution to an equation within a specified domain or range. For example, in the context of square roots, the principal root is the non-negative solution.
