A catalyst undergoes no chemical change during a chemical reaction.
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the 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.
This chemical reaction is called dehydration.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
A reaction that emmits heat is called an exothermic reaction .
A catalyst doesn't undergo a chemical change during a chemical reaction.
That would be the product of the chemical reaction.
ENzyme
A chemical change that gives off heat. Burning paper would be an example.
No. Product is the new material formed during the chemical reaction.
