In a chemical change chemical properties often change (like a substance's melting point or it's reactivity). In a physical change the materials have the same properties (a physical change would be like crushing rocks into sand). You can take wood, grind it into saw dust, but it is still wood. But if you burn it, the wood goes through a chemical change with the oxygen in the air and most of it is broken down into a gas (smoke) and the solid of which is left behind has a very different flammability property. (Suit, it doesn't burn.)
What else can I help you with?
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What describes the reactants and products involved in a reaction?
Reactants are the substances that are consumed or used up in a chemical reaction to form products. Products are the new substances that are formed as a result of the reaction between the reactants.
How are the terns reactant product and chemical reaction related?
In a chemical reaction, reactants are the substances that undergo a change to form products. Reactants are written on the left side of a chemical equation, while products are written on the right side. The chemical reaction is the process by which reactants are transformed into products through the breaking and forming of chemical bonds.
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.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
What are substance you start with in a chemical reaction called?
The reactants
The elements or compounds produced by a chemical reaction are known as what?
The substances produced by a chemical reaction are known as Products. The substances that are reacted are the Reactants.
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
What are the reactants and products of the forward reaction?
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
In chemical reaction the products are?
reactants
What substances do you have at the beginning of a chemical reaction?
The substances you have at the beginning of a chemical reaction are the reactants or the reagents.
What are the reactants and the products of the forward Left to right reaction?
Reactants- The substances used up in a reaction. Products- The new substances made.
Why are reactants important in a chemical reaction?
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
What are the reactants and the products of a written chemical reaction?
reactants are on the left and the products are on the right
Where are the reactants and products identified in a chemical reaction?
Reactants are to left and products are to right.
What turns on a chemical reaction?
In a chemical reaction reactants are transformed in products.
Does endothermic favor reactants or products in a chemical reaction?
Endothermic reactions favor the reactants in a chemical reaction.
