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 a reaction?
The amount of energy that is used or released as heat in a reaction.
How is hess law used to measure enthalpy of a desired reaction?
... Intermediate equations with known enthalpies are added together.
How is Hess's law used to measure enthalpy of a desire reaction?
... Intermediate equations with known enthalpies are added together.
Is a symbol which stands for the value equal to the entirely enthalpy minus the temperature times enthropy . It can be used to determine if a reaction will take place?
The change in Gibbs Free Energy (∆Gº) predicts if a reaction is spontaneous or not. The equation for this is ∆G = ∆H - T∆S where ∆H is the change in enthalpy, T is temperature in Kelvin, and ∆S in change in entropy.
What does the enthalpy reaction measures?
The amount of energy that is used or released as heat in a reaction.
What does the enthalpy of reaction measure?
The amount of energy that is used or released as heat in a reaction.

The instrument used to determine the volume changes in chemical reaction is known as?
For fluids, a buret is a good one.
What is the enthalpy of a reaction?

What describes how much energy is produced or used during a chemical change?
The enthalpy of reaction
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 bond formation and bond breaking related to enthalpy?
Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.
What is an instrument used to determine humidity?
hygrometer
