WebThe scientific word for burning is combustion. All combustion reactions give off heat into their surroundings. So they’re described as exothermic reactions. But there are other … WebDec 11, 2016 · Clearly, the reaction is "exothermic". You are burning ethane; normally, the gas supplied to homes and labs is methane, CH_4. CH_4(g) +2O_2(g) rarr CO_2(g) +2H_2O(g) The stability of the C=O and O-H bonds means that energy is released upon their formation, and the reaction is "exothermic". Most combustion reactions, e.g …

WebApr 11, 2024 · 3. Feels warm to the touch: Since energy is released to the surroundings, an exothermic process often feels warm to the touch. 4. Examples: a. Combustion: Burning of fuel, such as wood or gasoline, releases heat energy to the surroundings. b. Freezing of water: When water changes from liquid to solid state, the lost energy is released as heat. c. WebEndothermic vs Exothermic Reactions Some reactions are endothermic which absorb energy. Photosynthesis is an endothermic reaction.

Chemistry. Chemistry questions and answers. 1. Two examples of combustion reactions are burning a log in a fireplace or burning gasoline in a car. Are these endothermic or exothermic reactions? 2. What affect does the concentration of reactant have on the rate of a reaction? WebEnergy is also needed for the fossil fuel to react with oxygen, so the energy use portion of combustion is an endothermic reaction into or absorbing. In summary, combustion is a "burning" of fossil fuels in order to release heat energy, and the primary byproduct of combustion is carbon dioxide (CO 2). → » tasmania october public holiday
