What is the relationship between the heat of reaction and the heat of formation in a chemical reaction?
The heat of reaction is the difference between the heat of formation of products and reactants in a chemical reaction. It represents the amount of heat released or absorbed during the reaction. The heat of formation is the heat change when one mole of a compound is formed from its elements in their standard states. The relationship between the two is that the heat of reaction is related to the heat of formation of the substances involved in the reaction.
What is the difference between the heat (q) of a reaction and the reaction enthalpy (Hrxn)?
The heat (q) of a reaction is the amount of energy transferred as heat during a chemical reaction, while the reaction enthalpy (Hrxn) is the overall change in heat energy of a reaction at constant pressure. The main difference is that heat (q) is the actual energy transferred, while reaction enthalpy (Hrxn) is a measure of the total heat change in a reaction.
What is the difference between the heat of reaction and the heat of combustion?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction, while the heat of combustion specifically refers to the heat released during the combustion of a substance with oxygen.
What is the difference between enthalpy and heat of reaction in a chemical reaction?
Enthalpy is the total heat content of a system, including both heat absorbed and released during a reaction. Heat of reaction specifically refers to the heat released or absorbed when a specific chemical reaction occurs.
What is the difference between the heat of reaction and enthalpy in a chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction, while enthalpy is the total heat content of a system. Enthalpy includes the heat of reaction as well as any changes in pressure and volume.
What is the the molar heat of reaction for the reaction between hydrochloric acid and potassium hydroxide?
alkaline

What is the difference in specific heat between hydrogen and oxygen molecules?
The molar heat capacity of hydrogen (H2) is 28,835 J/mol/K.The molar heat capacity of oxygen (O2) is 29,378 J/mol/K.

How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.

What is molar enthalpy change?
Molar enthalpy change, also known as molar enthalpy of reaction, is the amount of heat energy released or absorbed during a chemical reaction per mole of a substance. It is usually expressed in units of kJ/mol. The molar enthalpy change can be positive (endothermic) if heat is absorbed or negative (exothermic) if heat is released during the reaction.
What is the difference between the enthalpy of the products and the enthalpy of the reactants in a chemical reaction?
The difference between the enthalpy of the products and the enthalpy of the reactants in a chemical reaction is known as the change in enthalpy, or H. This value represents the amount of heat energy either absorbed or released during the reaction. If H is positive, the reaction is endothermic and absorbs heat. If H is negative, the reaction is exothermic and releases heat.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
What is the difference between an endergonic and endothermic reaction?
An endergonic reaction requires energy input to occur, while an endothermic reaction absorbs heat from its surroundings.
