Is the enthalpy change of the chemical reaction between a monoprotic acid and sodium hydroxide the same for all strong monoprotic acids?
The reaction that occurs between a strong monoprotic acid and sodium hydroxide is H++OH- => H2O. This reaction is the same for all strong monoprotic acids and sodium hydroxide so, in theory, they should all have the same standard enthalpy of reaction. In practice, there are very slight differences between acids. If you are in a freshman or sophmore chemistry class, say yes. If you are in physical or analytical chemistry say no.

What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Does the overall enthalpy change of a chemical reaction depend on the reaction pathway?
No, the overall enthalpy change of a chemical reaction is independent of the reaction pathway. This is because enthalpy is a state function, meaning it only depends on the initial and final states of the system, not on how the system reached those states.
What does it mean if the change in enthalpy value for a chemical reaction is positive?
A positive change in enthalpy for a chemical reaction indicates that the reaction is endothermic, meaning it absorbs heat from its surroundings. This typically results in the surroundings feeling cooler.
What is a monoprotic base?
A monoprotic base is a molecule that has one functional group that can accept a proton. NaOH for example is a (strong) monoprotic base because it can accept one proton. But amines can also be monoprotic bases.

When does heat equal enthalpy in a chemical reaction?
Heat equals enthalpy in a chemical reaction when the reaction is carried out at constant pressure.
Why is the enthalpy of reaction between sodium hydroxide and sulfuric acid different from that of sodium hydroxide and hydrochloric acid?
The enthalpy of reaction between sodium hydroxide and sulfuric acid is different from that of sodium hydroxide and hydrochloric acid because sulfuric acid is a diprotic acid, which means it releases two moles of H+ ions per molecule. This leads to a different stoichiometry in the reaction and results in a different enthalpy change compared to the reaction with hydrochloric acid, which is a monoprotic acid releasing only one mole of H+ ions per molecule.

Is enthalpy conserved in a closed system undergoing a chemical reaction?
Enthalpy is not conserved in a closed system undergoing a chemical reaction.
How do you calculate the change in enthalpy for a chemical reaction?
To calculate the change in enthalpy for a chemical reaction, subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the change in enthalpy for the reaction.
What does a negative enthalpy indicate in a chemical reaction?
A negative enthalpy in a chemical reaction indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings.
IS HCLO4 a monoprotic?
Yes, HClO4 is a monoprotic acid because it can donate only one proton (H+ ion) in a chemical reaction.
