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.
What is enthalpy of solution?
enthalpy is how many miles superman can travel in a day. Regards, Lois Lane
True or false The molar enthalpy values and fusion stay the same if you were to reverse the process?
True. The molar enthalpy values for fusion (also known as the enthalpy of fusion) are independent of the direction of the process. This means that the enthalpy change for melting a substance is equal in magnitude, but opposite in sign, to the enthalpy change for freezing the substance.
Why does oxygen gas not have an enthalpy of formation but ozone does?
Oxygen gas (O2) does not have an enthalpy of formation because it is an element in its standard state, which has an enthalpy of formation of zero by definition. Ozone (O3), on the other hand, is a compound and has a defined enthalpy of formation because it is formed from its elements in their standard states.
What is the difference of enthalpy of formation and the enthalpy of combustion?
The enthalpy of formation is the change in enthalpy that occurs when 1 mole of a compound is formed from its elements in their standard states. The enthalpy of combustion is the change in enthalpy that occurs when 1 mole of a substance is completely burned in oxygen. In short, enthalpy of formation is for the formation of a compound, while enthalpy of combustion is for the complete burning of a substance.
How do you make a sentence for enthalpy?
Enthalpy is a thermodynamic property of a thermodynamic system.
What is the enthalpy of HDPE?
The enthalpy of high-density polyethylene (HDPE) can vary depending on its specific form and conditions. However, HDPE typically has a heat of fusion enthalpy of around 110 J/g.
What characteristics of a substance is NOT affected by enthalpy and entropy?
Pressure is not affected by enthalpy and entropy.pressure
What is the difference between enthalpy change and enthalpy change per mole?
Enthalpy change is the total heat energy exchanged during a process, while enthalpy change per mole is the heat energy exchanged per mole of a substance during the same process. The enthalpy change per mole allows for comparison between different reactions on a per mole basis, making it a more useful measure when analyzing chemical reactions.
Define enthalpy and how it is measured?
Enthalpy is a particular amount of heat that is produced or released at a given pressure. There are specific equations that must be used to calculate enthalpy.
What is the standard enthalpy for sodium sulfate?
The standard enthalpy of formation for sodium sulfate is -1385.2 kJ/mol.
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.
What is the description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is the enthalpy of calcium chloride?
The enthalpy of formation of calcium chloride is -795.8 kJ/mol.
What is the enthalpy of N204 ---2NO O2?
The enthalpy change for this reaction is -76 kJ/mol.
