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.
What happens when electrons are gained or lost?
Gain or electron means reduction energy is not gained but given off during this and also when oxidation takes place the same thing thing happens' energy is released when a redox reaction takes place(ie both oxidation & reduction)
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.
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.
A reaction in which energy is taken in?
base
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.
Does energy decrease or increase during a chemical reaction?
Energy is only made not taken away. But during a chemical reaction, it depends on what kind of chemicals you put in there.

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
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.
What changes gives NO evidence that a chemical reaction has taken place?
Physical changes give no evidence that a chemical reaction has taken place, because no chemical reaction has taken place.
Is bananas turning black if you leave them in a warm cupboard for a week a chemical reaction and why?
Yes, it is a chemical reaction, because the colour of the banana has changed, which shows that a chemical reaction has taken place. Also, if the banana has gone black and turned bad, you can't change it back to it's original form, which proves that it is a chemical reaction and not a physical reaction. Remember - A chemical reaction has definitely taken place if : It's colour has changed A gas is given off There are energy changes Or, it can't be changed back to what it used to be! :) Hope this helps!!
Which is more energy given off than taken in A exothermic reaction an endothermic reaction a diluted solution or a concentrated solution?
exothermic
