Any chemical reaction creates a new substance.
no
The majority of chemicals can react.
In any chemical equation you start with reactants and end up with products.
The products
A reaction has two components with the reactant as an "ingredient," and the product is the end result. A combustion reaction as the reactants of O2 (oxygen) and CH4 (methane). Their product through the reaction CH4 + 2O2 is 2H2 (water) and C02 (carbon dioxide).
A chemical reaction begins with reactants and ends with products.
The products. Reactants -----> product
Enzyme or catalyst
No, that is a catalyst. An enzyme is a type of catalyst, though.
no
These chemicals are called reactants.
The majority of chemicals can react.
The act of mixing chemicals is a physical process, not a chemical reaction. Mixing chemicals together may, or may not, allow a chemical reaction to proceed, depending on the nature of the chemicals being mixed.
The products
In any chemical equation you start with reactants and end up with products.
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
a chemical reaction is a reaction were the two chemicals change into a new chemical.
