How should a student use a thermometer to determine if a reaction is exothermic?
To determine if a reaction is exothermic, a student should use a thermometer to measure the temperature change during the reaction. If the temperature increases, it indicates that the reaction is exothermic, releasing heat.
What can be said about an exothermic reaction with a negative entropy change?
An exothermic reaction with a negative entropy change indicates that the reaction releases heat to its surroundings and results in a decrease in disorder or randomness of the system.
What does a negative deltaH tell about a reaction?
the reaction is exothermic
Where does the energy term appear in the equation for an exothermic reaction?
In an exothermic reaction, the energy term appears as a product in the chemical equation. This indicates that energy is released as the reaction proceeds, resulting in a net decrease of energy in the surroundings.
What does a negative H tell about a reaction?
A negative change in enthalpy (ΔH) indicates that a reaction is exothermic, meaning it releases heat to its surroundings. This suggests that the products have less energy than the reactants, leading to a decrease in enthalpy during the reaction.

To determine if a reaction is exothermic, a student should use a thermometer to measure the temperature change during the reaction. If the temperature increases, it indicates that the reaction is exothermic, releasing heat.
How can you tell whether a reaction is endothermic or exothermic?
You can determine if a reaction is endothermic or exothermic by observing the temperature change of the surroundings. In an exothermic reaction, heat is released, causing the temperature of the surroundings to rise, while in an endothermic reaction, heat is absorbed, leading to a decrease in the temperature of the surroundings. Additionally, you can analyze the enthalpy change (ΔH); a negative ΔH indicates an exothermic reaction, while a positive ΔH indicates an endothermic reaction.

How To determine if a reaction is exothermic a student should use a?
To determine if a reaction is exothermic, a student should use a calorimeter to measure the temperature change of the reaction mixture. If the temperature increases during the reaction, it indicates that heat is being released to the surroundings, confirming that the reaction is exothermic. Additionally, examining the enthalpy change (ΔH) for the reaction can also provide insight; a negative ΔH value signifies an exothermic process.
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.
What does a negative H tell about a reaction?
A negative change in enthalpy (ΔH) indicates that a reaction is exothermic, meaning it releases heat to its surroundings. This suggests that the products have less energy than the reactants, leading to a decrease in enthalpy during the reaction.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
Is the reaction endothermic or exothermic, and what is the enthalpy of the reaction?
The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.
Is KCI plus AgNO3 AgCl plus KNO3 Endothermic or exothermic?
The reaction between KCl and AgNO3 to form AgCl and KNO3 is an exothermic reaction. When these two ionic compounds react, they form a solid precipitate of silver chloride (AgCl) and release energy in the process. This release of energy indicates that the reaction is exothermic.
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
