An endothermic reaction is when energy is absorbed. An exothermic reaction releases energy. At times, it is difficult to remember the difference. Answer and Explanation:1 The prefixes of the words help one to remember which is which. Thermionic is related to heat, like thermal underwear.You als...

Some chemical reactions release energy by heat. In other words, they transfer heat to their surroundings. These are known as **exothermic** reactions: "Exo" relates to external, or outside, and "thermic" means heat. Some examples of exothermic reactions include combustion (burning), oxidation ...
The liquid inside the cold pack iswater. In the water is another plastic bag or tube containingammonium-nitrate fertilizer. When you hit the cold pack, it breaks the tube so that the water mixes with the fertilizer. This mixture creates anendothermicreaction -- it absorbs heat. The temperatur...
To build that connection, the product has to speak of itsuseful effect. Informing that you are out there is not auseful effect. Take a look at these pieces: Back Door Roasters makes unique blends of coffee and runs them through endothermic and exothermic roasting processes at 175ºC which...
during combustion, the flame retardants decompose in radical species able to quench the high-energy free radicals formed during cellulose combustion (e.g., H• and •OH) by decreasing the burning rate of the combustible materials and, finally, interrupting the exothermic reactions of the ...
(exothermic reaction) (12) In this regard, researchers are working on the development of new flame-retardant agents and nanocomposites, employing different nanomaterials and compounds such as the ones shown in Figure 8a. The addition of a relatively modest loading level of around 5 wt% of nanom...
