What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What are the two basic parts of a chemical reaction?
Chemical reaction is the making and breaking of chemical bonds, leading to changes in the composition of matter. Chemical reactions do not create or destroy matter; they only rearrange it in various ways.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
What must be true about the properties of the reactants and the properties of the products in a chemical reaction?
The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.
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 are substance you start with in a chemical reaction called?
The reactants
What represents the correct way to write a chemical equation reactants--products products equals reactants reactants equals sum sum--- reactants?
reactants ---> products
Where are the reactants and products identified in a chemical reaction?
Reactants are to left and products are to right.
What are the reactants and the products of a written chemical reaction?
reactants are on the left and the products are on the right
How do reactants and products and compar before and after a chemical reactgion?
The products have different physical and chemical properties than the reactants.
What happens to the reactants when a chemical change occurs?
The reactants change & turn into products.
How do reactants and products compare in a chemical reaction?
Reactants are what the products are made out of. The products are the end result.
What represents the correct way to write a chemical equation reactants ----- products products equals reactants reactants equals sum sum ---- reactants?
reactants -----> products is correct
What is the arrow between the reactants and products?
The arrow between the reactants and products in a chemical equation represents the direction of the chemical reaction. It indicates that the reactants are being transformed into the products.
In chemical reaction the products are?
reactants
What are the substances found on the left side of the arrow in a chemical equation called?
products The chemical on the right side of the chemical equation are generally referred to as products. (Although in reversible chemical reactions, they can also be thought of as reactants.)
When do reactants give products?
They give products when they are brought together and react.
