Catalysts
A chemical reaction is a process in which new substances are formed.
The chemicals at the start of a reaction are always called the reactants.The chemicals at the end of a reaction are always called the products.
they are called products.for egsample if copper and oxygen were your reactants copper oxide would be the new substance made and it would be called your product.reactant+reactant=product
Yes, new substances are produced in a chemical change or chemical reaction. There are many examples of this, but one might be the combustion (burning) of hydrogen gas in air. Hydrogen gas will combine with oxygen when it burns, and the result is water. Both hydrogen and oxygen are gases at normal temperature and pressure, and the balanced chemical equation is: 2H2 + O2 => 2H2O
Yes becasue when the atoms inside the wax start to change, they all form and become a solid. this is what is now called replacement.
These substances are called reactants.

The reactants
The chemicals at the start of a reaction are always called the reactants.The chemicals at the end of a reaction are always called the products.
The substances that are present when a chemical reaction begins are reactants, at the end of the reaction they form products.
reactants is your answer
When atoms of two different elements join together (or combine) to make molecules of a compound, scientists say that a Chemical Change or Chemical Reaction has taken place. I you look at the substances you start off with and the substance you get after the change, they are often different.
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.
they are called products.for egsample if copper and oxygen were your reactants copper oxide would be the new substance made and it would be called your product.reactant+reactant=product
I think that a chemical equation tells a chemist that substances you start with and substances you end with
