it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.

Is the process of KNO3 dissolving in water spontaneous at all temperatures studied?
yes delta s is positive, delta h is negative making delta g negative at all temps
What could make delta G become negative at a given enthalpy and entropy?
The equation for ∆G is ∆G = ∆H - T∆S H is enthalpy and S is entropySo, ∆G is negative if T∆S is greater than ∆H
What is delta h in the equation delta g delta h - t delta s?
The change in enthalpy between products and reactants in a reaction
What is the delta H deg f of potassium?
What is the delta H deg f of potassium?
What is delta H for HCl aq?
the delta h for x hydrogen and x chlorine because it is aq and dissociates in water into h+ ions and cl- ions
Is the process of KNO3 dissolving in water spontaneous at all temperatures studied?
yes delta s is positive, delta h is negative making delta g negative at all temps
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)

How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
What conditions make delta G always positive?
G is always positive when enthalpy increases and entropy decreases.
What is delta h in the equation delta g delta h - t delta?
The change in enthalpy between products and reactants in a reaction
What is hydration energy?
Hydration Energy is involved in the solution process. The solution process involves three steps all including a change in enthalpy. The first delta H (change in enthalpy) is the process by which water molecules overcome attractive forces in the solute particles to break chemical bonds. This process is endothermic. The second step delta H 2 is the separation of solvent molecules to accommodate the solute. This step also requires energy and is endothermic (delta H is greater than 0) The final step is the formation of new attractive interactions between solute and solvent particles and is exothermic (delta H is less than 0). The sum of delta H 1, 2, and 3 is the overall enthalpy of the solution process and this sum is known as the hydration energy. If the sum of delta H 1 and 2 is greater in magnitude than the delta H 3 (which is a negative number) the overall process will be endothermic. If the sum of delta H 1 and 2 is lesser in magnitude than delta H 3 the overall process will be exothermic.
What is delta h in the equation delta g delta h - t delta s?
The change in enthalpy between products and reactants in a reaction
What is the delta H deg f of potassium?
What is the delta H deg f of potassium?
Delta H equals delta E plus delta nRT prove?
Yes
What is true when two reactants combine in an exothermic reaction?
Exothermic Reactions: The delta h is always NEGATIVE! Energy is released (delta is the little triangle in front of the H)
