What else can I help you with?
What type of substances start a chemical reaction?
These substances are called reactants.
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 are the substances you start with in a chemical reaction called?
The substances you start with in a chemical reaction are called reactants. Reactants are the starting materials that undergo changes to form new substances called products.
What compound is needed to start a chemical reaction?
The initial compounds in a chemical reaction are called reactants.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
What is the name given to the substances at the start of a reaction?
The substances at the start of a chemical reaction are known as reactants. Reactants are the molecules or compounds that undergo a chemical change during the reaction. They are typically written on the left side of a chemical equation, while the products of the reaction are written on the right side. The reactants are consumed during the reaction to form the products.
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 substance you start with in a chemical reaction called?
The reactants
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.
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.
What are rectants?
Reactants are the substances that are present at the start of a chemical reaction and are consumed in the process to produce the products. They undergo chemical changes or interactions to form new substances during the reaction.
Are substances at the end of the reaction are called the reactants?
No, the substances at the start of a chemical reaction are called the reactants. They are transformed into different substances known as products through the course of the reaction.
