What describes the reactants and products involved in a reaction?
Reactants are the substances that are consumed or used up in a chemical reaction to form products. Products are the new substances that are formed as a result of the reaction between the reactants.

A chemical reaction begins with a substance called and ends with substance called?
Pure substances (or ELEMENTS) form COMPOUNDS after a chemical reaction. For example: Sodium and chlorine, when fused in a chemical reaction become the compound Sodium-Chloride The substance you have in the beginning of a chemical reaction are called reactants and the substance you have when chemical reaction is complete is called products.
What catalyzes chemical reaction?

Cutting up a pear chemical reaction or reversible?
It's chemical because you can't get the pear back to a whole.
Is cutting up a pear a reversible change or a chemical reaction and why?
You can't glue together a divided pear,if you want it to be valuable but it is not a chemical change..why?-The reason is that a chemical change is followed by entirely new product and what you have done is to seperate the pear molecules,it is still a pear!,and it is a physical change,and you are free to ask more question,because I understand that a pear has life..
Is cutting up a pear a chemical?
No it isn't, however, the oxidation of the organic material that occurs after the Pear has been cut, is a chemical reaction, it is called Redox.
Why is cutting up a pear irreversible?
irreversible
Is cutting up a pear a reversible change?
no because you cannot really get it back to a whole pear.
How do you prevent pear molding?
Try cutting them up and freezing them
