What is a substance that enters into a chemical reaction called.?
The reactant is the substance present at the start of a chemical reaction, while the product is the substance(s) formed from a chemical reaction.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What is a chemical substance that helps control reactions?
A catalyst is generic term used to influence rates of reaction. The catalyst lowers the activation energy required to start the reaction. In biology, catalysts are called enzymes.
The substances present when a chemical reaction begins?
The substances that are present when a chemical reaction begins are reactants, at the end of the reaction they form products.
What is a substance that enters into a chemical reaction called.?
The reactant is the substance present at the start of a chemical reaction, while the product is the substance(s) formed from a chemical reaction.
What is the substance present at the start of a reaction?
The substance present at the start of a chemical reaction is called a reactant. Reactants are the starting materials that undergo chemical changes to form products during a reaction.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is a substance that results in a chemical change called?
A substance that results in a chemical change is called a reactant. Reactants are substances that are present at the start of a chemical reaction and are transformed into different substances (products) during the reaction.
What are the substance you start with in a chemical reaction?
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 term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?

What term describes a substance that lowers the energy needed to start a chemical reaction?
This substance is a catalyst.
What compound is needed to start a chemical reaction?
The initial compounds in a chemical reaction are called reactants.
What is an element or compound that enters into a chemical reaction?
A reactant is a substance that enters into a chemical reaction and is transformed into a new product. It is present at the start of the reaction and gets consumed during the process.
What is a chemical reactants and the products in the reaction?
Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
What term describe a substance that lowers the amount of energy needed to start a chemical reaction?
