What else can I help you with?
In a chemical reaction the total mass of the substances before the reaction is?
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
What are the substances that are present before the reaction called in science?
The substances present before a chemical reaction are called reactants. These are the starting materials that undergo a transformation to form new products during the reaction.
What is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
What materials present after a reaction?
After a chemical reaction, the materials present can include reactants, products, byproducts, and any leftover starting materials that did not react. The specific materials depend on the reactants used and the conditions of the reaction. Analytical techniques such as chromatography, spectroscopy, and mass spectrometry can help in identifying the various materials present after a reaction.
What is the opposite of reactants?
When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
Substances that are present before the reaction?
Substances that are present before the reaction are called "reactants" or "reagents".
Are the substances present before the reaction?
Substances that are present before the reaction are called "reactants" or "reagents".
What do you call the substances before a chemical reaction takes place?
These initial substances are the reactants.
In a chemical reaction the total mass of the substances before the reaction is?
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
What are the substances that are present before the reaction called in science?
The substances present before a chemical reaction are called reactants. These are the starting materials that undergo a transformation to form new products during the reaction.
What do you call the substaces before a chemical reaction takes place?
The initial substances in a reaction are called reactants.
What is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
What is the difference between a chemical reaction and a chemical composition?
when 2 or more compounds react chemically to form a new compound then it is called chemical reaction chemical reaction whereas the quantity and no. chemical elements presents in chemical compound is called the chemical composition
Who say one may take it for granted that in every reaction there is an quantity of matter before after?
Antoine Lavoisier stated that in every chemical reaction, the total mass of the substances before the reaction is equal to the total mass of the substances after the reaction. This principle is known as the law of conservation of mass.
What are substances that exist before a reaction begins?
The reactants react to produce a product.
What is one of of the original substances before a chemical reaction takes place?
a reactant
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.
