What is a chemical reaction in which more energy is given off than taken in?

Combustion, burning, releases more heat that is taken in to start the reaction.


Can energy be taken in a chemical reaction?

Depending on the particular chemical reaction, energy may be either released or absorbed.


Can energy be taken only during a chemical reaction?

Depending on the particular chemical reaction, energy may be either released or absorbed.


What are 2 results from a chemical reaction?

Usually new products and a change in energy. Usually heat is given out, but occasionally heat is taken from the surroundings.


Is more energy absorbed than released is the result of an endothermic chemical reaction?

In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.


Does energy decrease or increase during a chemical reaction?

Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.


What does the different in potential energy between the reactant and products represent?

It represents the change in enthalpy for the reaction.


What is difference between released chemical energy and absorbed chemical energy?

When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction. When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.


Which is more energy given off than taken in A exothermic reaction an endothermic reaction a diluted solution or a concentrated solution?

exothermic


What evidence is there to show that a chemical reaction has taken place when an egg is cooked?

The change in color indicates that a chemical reaction has taken place.


What two things can happen to energy in a chemical reaction?

well you see now, a lot of things can happen. 1. the chemical reaction will slow down because of the energy being wasted. 2. the chemical reaction will not work anymore because it was wasted and now has no energy. HOPE THAT HELPED


Energy can be taken in only during a chemical reaction?

No, chemical reactions are not the only reactions that may involve absorption of energy. A physical change like heating water to vapor is also endothermic.
