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.
Is it true that when an enzyme promotes a chemical reaction by lowering the activation energy it only affects the rate of the reaction?
yea
Would it ever be true that matter and energy may be created or destroyed in a chemical reaction?
false
What is true about enzyme?
Enzymes lower the energy required for a chemical reaction.
What is an antonym of chemical reaction?
I suppose that "chemical reaction" hasn't not a true antonym.
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.?

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.

yea
Would it ever be true that matter and energy may be created or destroyed in a chemical reaction?
false
What is true about enzyme?
Enzymes lower the energy required for a chemical reaction.
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.
What is true for all exergonic reaction?
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
