in a exothermic reaction temperature changed from 30 to 43, reasons why I got those answers
It depends on what you were measuring.
my point is, something gained (absorbed..endothermic) heat, whatever you measured. Where did the heat come from?
To understand why the temperature changed from 30 to 43 in an exothermic reaction, we need to understand the concept of exothermic reactions and how they affect temperature.
An exothermic reaction is a chemical reaction that releases heat into its surroundings. In these reactions, the energy released by the reaction exceeds the energy required to break the bonds of the reactants. As a result, the excess energy is released in the form of heat, causing an increase in temperature.
In your case, the temperature changed from 30 to 43. This indicates an increase in temperature, which is consistent with an exothermic reaction.
There could be several reasons why the temperature increased specifically from 30 to 43:
1. Heat of reaction: The reaction itself may have a high heat of reaction, meaning it releases a significant amount of heat. This could be due to the nature of the reactants and the specific reaction conditions.
2. Stoichiometry: The stoichiometry of the reaction could cause a specific increase in temperature. The stoichiometry refers to the balanced equation of the reaction, which determines the ratio of reactants and products. If the reaction is designed to have a specific heat change, it could result in a targeted increase in temperature.
3. Concentration: The concentration of reactants could affect the temperature change. Higher concentrations of reactants could result in a more significant temperature increase.
4. Reaction conditions: The reaction conditions such as pressure and presence of a catalyst can influence the temperature change. If the reaction is carried out under specific conditions that favor a higher temperature increase, it could explain the change from 30 to 43.
It's important to note that without more information about the specific reactants and reaction conditions, it's difficult to pinpoint the exact reasons for the temperature change from 30 to 43. However, the general principles of exothermic reactions can help explain why the temperature increased in your case.
