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?
If you need to multiply the reaction by 2, you must also multiply the enthalpy change by 2. The final value for the enthalpy of the reaction used for the intermediate reaction would be 2 times the original enthalpy value.

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?
When you multiply a reaction by a factor, you also multiply the enthalpy change by the same factor. Therefore, if you multiply the reaction by 2, the final value for the enthalpy of reaction for the intermediate reaction will also be multiplied by 2.
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?
The final value for the enthalpy of the reverse reaction used in a Hess's law problem would simply be the negative of the original value of the enthalpy of the forward reaction. This is because reversing a reaction changes the sign of the enthalpy change.

What is true of the enthalpy value of an intermediate reaction?
It is multiplied by 2 if the intermediate reaction is multiplied by 2
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 interme?
To reverse a reaction in a Hess's law problem, you need to change the sign of the enthalpy change associated with that reaction. If the original reaction has an enthalpy of reaction ( \Delta H ), the final value for the enthalpy of the reversed reaction would be ( -\Delta H ). This allows you to correctly account for the energy change in the overall pathway when combining reactions.
If you need to reverse the following reaction and multiply it by 2 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?
If you need to reverse a reaction and multiply it by 2 in Hess's law, the enthalpy change of the reaction will also change sign and double in magnitude. This is because reversing a reaction changes the sign of the enthalpy change. Multiplying the reaction by a factor also multiplies the enthalpy change by that factor. Therefore, the final value for the enthalpy of the reaction will be twice the original magnitude but with the opposite sign.

What would be the final value for the enthalpy of reaction you use for this intermediate reaction C2H4 plus 3 O2 2 CO2 plus 2 H2O H -1410 kJ?
The final value for the enthalpy of reaction for the combustion of ethylene (C2H4) in your given reaction is -1410 kJ. This indicates that the reaction is exothermic, releasing 1410 kJ of energy as products (2 CO2 and 2 H2O) are formed from the reactants (C2H4 and 3 O2). Therefore, the enthalpy change, ΔH, for the complete combustion of ethylene is -1410 kJ.
What is the value of the enthalpy change of the uncatalyzed reaction?
The enthalpy change of an uncatalyzed reaction is the heat energy absorbed or released during the reaction when no catalyst is present. This value can be determined by calculating the difference between the enthalpy of the products and the enthalpy of the reactants.
What is true of the enthalpy reaction?
The enthalpy of a reaction is a measure of the heat energy exchanged with the surroundings at constant pressure. A negative enthalpy change indicates an exothermic reaction, where heat is released. A positive enthalpy change indicates an endothermic reaction, where heat is absorbed.
