What best describes an exothermic chemical reaction?

Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.

What defines an exothermic reaction?

An exothermic reaction is a chemical or physical reaction that releases heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.

Which is the best example of an exothermic reaction?

Exothermic reactions are chemical reactions that release energy as heat or light.
…
Some examples of combustion include:
  • Lighting a match.
  • A fireworks display.
  • Lighting coals on a barbeque.
  • Starting a gas oven.
  • Lighting firewood for a campfire.
  • Burning a piece of paper.

Which of the following describes an exothermic reaction quizlet?

Which of the following options correctly describes an exothermic reaction? It releases more energy by forming product bonds than is needed to break reactant bonds.

Which statement is the best description of a chemical reaction?

chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

What is exothermic chemical reaction give example?

An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water. Exothermic reactions are reactions that release energy into the environment in the form of heat.

Is exothermic a chemical reaction?

Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Chemical reactions that absorb (or use) energy are called endothermic.

Which of the following is an exothermic process?

Exothermic reactions are chemical reactions that release energy as heat or light. A large amount of heat is released when quick lime reacts with water, along with the formation of calcium hydroxide. Similarly, the process of dissolving an acid or base in water is a highly exothermic reaction.

Which example is an exothermic reaction quizlet?

When energy is being released, it is called an exothermic reaction. Exothermic reactions happen within our body eg. Respiration: Glucose + oxygen —– carbon dioxide + water + energy (energy is being released) that is why we feel hot after doing exercise.

How do you say exothermic reaction?
