Dissolving sodium chloride (NaCl) in water to form sodium cations (Na+) and chloride anions (Cl-) is an example of what kind of reaction? User: What are the products of combustion reactions?
Weegy: A combustion reaction is when all substances in a compound are combined with oxygen, which then produces carbon dioxide and water. Combustion is commonly called burning. [ It is an exothermic reaction, which means heat is produced and is easily distinguished. Combustion occurs predominantly in automobiles, homes, and in factories. An example of a combustion reaction is as follows: CxHy + O2 - > CO2 + H2O ] User: Why are metal alloys an example of a physical change and not a chemical change? User: List three signs that could make you think that a chemical reaction was taking place. User: What is an exothermic reaction? Weegy: An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction. User: Why do some reactions require energy from their surroundings? User: What occurs to the atoms of reactants in a chemical reaction? User: When is energy released during a chemical reaction? Weegy: In chemistry, Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction or, to transform other chemical substances. Examples include batteries and light bulbs. [ Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system. ] User: What is chemical energy User: Explain why energy is necessary to chemical reactions, and describe some common sources of energy. User: “Photosynthesis, the basis for all life on Earth, is an endothermic chemical reaction.” Explain. Weegy: Photosynthesis is so far the only way that solar energy is made available for the maintenance of organic life, [ scientists have invented solar cells that capture solar energy and transform it to electrical energy. ] (More)
