What are substance you start with in a chemical reaction called?
The reactants
In a chemical reaction a catalyst changes the 1.potential energy of the products 2.potential energy of the reactants 3. heat of reaction 4.activation energy?
A catalyst lowers the activation energy of a reaction, making it easier for the reactants to form products. It does not change the potential energy of the reactants or products, nor does it affect the overall heat of the reaction.
What are some characteristics of reactants?
Reactants are the substances present at the beginning of a chemical reaction. They are consumed during the reaction to yield products. Reactants typically undergo a transformation in their chemical structure or properties during the reaction.
What are the substances that are present before a chemical reaction starts?
The reactants exist before a reaction begins, and also the products are the result of the reaction of the reactants.
What are the materials you have at the beginning of a chemical reaction called?
The materials present at the beginning of a chemical reaction are called reactants. Reactants undergo a chemical change and transform into products during the reaction.
