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...
Is the reaction endothermic or exothermic? Explain. Find the enthalpy of reaction, DH for the reaction 2H2(g) + 2C(s) + O2(g) --->C2H5OH(l), using the following thermochemical data, and determine the reaction is endothe...
Answer to: How can chemists use the properties of a solute to predict if an enthalpy change of solution will be exothermic or endothermic? By...
This article is here to tell you everything you need to know about repairing your refrigerator and freezer yourself. You might be surprised to learn that repairs are actually quite easy, requiring only a little knowledge about the appliance and a little patience. Let's get started with some b...
and water and carbon dioxide are two products of a reaction, then it is probably a combustion reaction. Double-displacement reactions tend to involve ionic solutions that produce ionic compounds, one of which forms a precipitate; if you notice a precipitate in your reaction, you know it can li...
“I like to frame decaf roasting as similar to roasting a natural process coffee, because of the processing that happens,” says Mike. “Beans that have undergone our decaf process will move from their endothermic to exothermic states earlier and more aggressively than non-decaffeinated coffees,”...

a molecular level is you generally have a transfer of electrons. Depending on the reactants and a few other variables (this is very non-specific and simplified), you can have a reaction that absorbs heat from the surroundings (endothermic) or gives off heat to the surroundings (exothermic)....
At a Physics course at a University, many years ago, the professor thought to give his students the following assignment to answer: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)? Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools when it ...
