In an ordinary chemical reaction, energy is conserved, meaning the total energy before and after the reaction remains constant. This energy can be released or absorbed in the form of heat, light, or other forms, depending on whether the reaction is exothermic (releases energy) or endothermic (absorbs energy). Additionally, the energy changes often involve breaking and forming chemical bonds, which requires or releases energy. Overall, the law of conservation of energy dictates that energy is neither created nor destroyed, only transformed.
What else can I help you with?
Is it true that Every chemical reaction gives off energy?
yes it does <><><> No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
Is chemical energy potential energy?
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
Would it ever be true that matter and energy may be created or destroyed in a chemical reaction?
No, the law of conservation of matter and energy states that matter and energy cannot be created or destroyed in a chemical reaction. They can only be converted from one form to another.
What is an antonym of chemical reaction?
I suppose that "chemical reaction" hasn't not a true antonym.
Is chemical energy a type of potential energy due to the composition of a substance?
Yes, chemical energy is a type of potential energy stored within the chemical bonds of a substance. When these bonds are broken or rearranged during a chemical reaction, the stored energy is released in the form of heat or light.
True or false when a bond is broken in a chemical reaction heat energy is released?
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
Is IT true the higher the activation energy of a chemical reaction the easier it will be to get the reaction started.?

Is it true that Every chemical reaction gives off energy?

What is a true of a catalyst?
The catalyst is not a reactant in a chemical reaction but contribute to the success of this reaction.
Is it true that catalysts increase the activation energy needed to start a chemical reaction?
Catalysts actually lower the activation energy needed to start a chemical reaction. This makes the reaction happen more easily.
Is chemical energy potential energy?
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
If A chemical reaction occurs and the substances increase in temperature Does this break the law of conservation of energy?
No, an increase in temperature in a chemical reaction does not break the law of conservation of energy. The energy is simply being converted from one form to another – in this case, from chemical potential energy to thermal energy. The total energy before and after the reaction remains the same.
Would it ever be true that matter and energy may be created or destroyed in a chemical reaction?
No, the law of conservation of matter and energy states that matter and energy cannot be created or destroyed in a chemical reaction. They can only be converted from one form to another.
Which of the following is true for all exergonic reactions?
the reactants have more total energy than the products.
What is an antonym of chemical reaction?
I suppose that "chemical reaction" hasn't not a true antonym.
