Chemical changes release energy?
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
A chemical reaction that occurs in plants that changes light energy into chemical energy is?
photosynthesis
What is meant by thermodynamics of a chemical reaction?
It refers to the energy changes that take place during a chemical reaction.
What is the best term to describe a chemical reaction that absorbs heat energy?
An endothermic reaction.
How does the enthalpy temperature dependence affect the overall energy changes in a chemical reaction?
The enthalpy temperature dependence influences the overall energy changes in a chemical reaction by affecting the heat absorbed or released during the reaction. As temperature increases, the enthalpy change also changes, which can impact the reaction's energy balance.
Is changes in energy a chemical change?
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
What two things happen in a chemical reaction?
change in properties and changes in energy
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
What is the chemical reaction that changes food and oxygen into energy?
These are the metabolic reactions.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
What concept map using the terms endergonic and exergonic?
Endergonic and exergonic reactions are terms used to describe energy changes in chemical reactions. An endergonic reaction absorbs energy from its surroundings to proceed, while an exergonic reaction releases energy to its surroundings. These terms are often used to describe the energy balance of different cellular processes.
What are the changes that are exothermic?
exothermic chemical reaction is any reaction that releases energy to the enviorementex: burning a candle (heat energy is released) eutralization reaction
