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
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
What happen if a chemical reaction takes place in an open system?
matter can enter from the surroundings, but cannot escape to the surroundings. matter is not allowed to enter from or escape to the surroundings. matter cannot move at all. matter can enter from or escape to the surroundings.
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.
Elements or compounds that enter into a chemical reaction?
Reactants are the elements or compounds that enter into a chemical reaction. These substances are transformed into different products at the end of the reaction.
A chemical reaction that transfers energy from the reactants to the surroundings is reffered to as?
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
WHAT In an exothermic reaction energy is transferred from?
In an exothermic reaction energy is transferred from the system to the surroundings. An exothermic reaction is a chemical or physical reaction that releases heat.
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 substance you start with in a chemical reaction called?
The reactants
What defines an exothermic reaction?
A reaction that produces heat
What are the starting materials in a chemical reaction-?
Reactants
An endothermic reaction is one in which heat is transferred from the surroundings to the reactants?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing a decrease in temperature. This type of reaction requires an input of energy to proceed.
What are the materials you have at the beginning of a chemical reaction called?
The starting materials in a chemical reaction are called reactants.
Is an endothermic reaction one in which heat is transferred from the surroundings to the reactants?
Yes, an endothermic reaction is one in which heat is absorbed from the surroundings and transferred to the reactants. This results in a decrease in the temperature of the surroundings as energy is taken in during the reaction.
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 is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
