In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
What are substances that provide energy as the result of a chemical change?
These substances are called reactants, the reaction produces products. This type of reaction is called exothermic. As in the following reaction with the burning of methane: CH4 +2O2 ---> CO2 + 2H2O (reactants) (products)
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
Exothermic reaction
Is bond making exothermic or endothermic?
Bonds are both broken and made in an exothermic reaction, but in the end, the potential chemical energy of the products is less than the potential chemical energy of the reactants.
which of the following describes an endothermic reaction?
Hf, products > hf, reactants
What describes the potential energy diagram of an exothermic reaction?
The potential energy of the reactants is greater than the potential energy of the products.
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
What is the equation for exothermic reaction?
In exothermic reactions heat is liberated. So reaction can be reactants---->products+heat
What equation show exothermic reaction?
Hf, reactants > Hf, products

What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What describes the two phases is dynamic equilibrium?
reactants are turning into products. products are turning into reactants.
Which do the following best describes a neutralization reaction?
A neutralization reaction has as reactants a base and an acid and as products water and a salt.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
What describes what happens when reactants reorganize to form products?
A chemical reaction occurs when reactants reorganize to form products. However, a chemical equation is a written form that describes what we've observed when reactants reorganize to form products.
In an exothermic reaction the products have a what type of bond?
An exothermic reaction can produce a covalently bonded compound or an ionically bonded one. It depends on the starting reactants.
