How do energy changes affect whether a chemical reaction will occur?
Energy is released or absorbed whenever chemical slave are formed or disconsolate during chemical reactions. Energy changes are one of the interior significant factors in determining whether a chemical reaction antipathy occur. … Chemical reactions that swallow energy antipathy not befall without a material of energy.
What is the best definition of chemical change?
A chemical vary is a vary of materials inter another new materials immediately particularize properties and one or good-natured sooner_than one new substances are formed. It results when a matter combines immediately another to agree a new matter (synthesis or either decomposes to agree good-natured substances).
What is the relationship between Chemical Reactions and changes in the energy of the molecules involved?

What form of energy is there before the chemical change?
Answer: Thermal energy can be reflection of as a reactant in the occurrence of an endothermic reaction and can be reflection of as a catalyst when it simply provides the activation energy to initiate a exothermic reaction such as lighting a fire.
What causes the change in energy?
The energy vary that occurs as the ant: fail of a reaction depends on the separation between the energy of the reactants and the energy of the products. For reactions resembling combustion the fuel (for sample wood) has energy stored in the chemical slave between the atoms that exult it up.
What energy changes occur when chemical bonds are formed and broken?
Energy is absorbed to fracture bonds. Bond-breaking is an endothermic process. Energy is released when new slave form. Bond-making is an exothermic process.
