How is Hess's law used to measure enthalpy of a desire reaction?
... Intermediate equations with known enthalpies are added together.
What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
What is true of the enthalpy value of an intermediate reaction?
It is multiplied by 2 if the intermediate reaction is multiplied by 2
What would be the final value for the enthalpy of reaction you use for this intermediate reaction?
-2820 kJ APEX
If you need to multiply the reaction by 2 to be an intermediate reaction in a hess law problem what would be the final value for the enthalpy of reaction you use for this intermediate reaction?
-572k
If you multiply the following reaction by 2 to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this intermediate reaction?

What is a correct description of the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the intermediate reactions.
If you need to multiply the following reaction by 2 to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this intermediate reac?
-572k
What does Hess's law say about the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the reactant path taken.
If you need to reverse the following reaction in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this in?
1410 kJ
What does Hesses law state?
The enthalpy of a reaction is the sum of the enthalpies of intermediate reaction.
