in the course of a chemical reaction, of the reactants initially contain 245 j of chemical energy and the final products contain 115 j of chemical energy, how much thermal energy is transferred to the surroundings?

Respuesta :

The thermal energy is transferred to the surroundings is 130 J.

Energy is a quantitative property given to a body or physical system and can be identified as work being done in the form of heat and light. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed. Energy is the ability to do work. It can exist in electrical, kinetic, thermal, electrical, chemical, nuclear, or other forms.

Calculation:-

initial energy = 245 J

final energy = 114 J

energy transferred to the surroundings = 245 -115

                                                                 = 130 J

Energy exists in many forms. Examples include light energy, thermal energy, mechanical energy, gravitational energy, electrical energy, acoustic energy, chemical energy, and nuclear or atomic energy. Each form can be transformed or changed into other forms.
