Endothermic

concentration of the reactants. Moreover, an additional factor may be the type of reaction, either endothermic or exothermic. An exothermic reaction requires less energy to overcome the activation energy, whereas as the reverse endothermic reaction would require more energy. In addition, the forward exothermic reaction will have a larger barrier than the reverse exothermic reaction, and thus, the endothermic reaction will be slower. Therefore, because these magnesium-acid reactions are…

The purpose of this experiment has been met and all heat changes in each part of the experiment were measured. In Part I we had to calculate the specific heat (SH) and the atomic mass of a metal. In this case, Copper was examined and the specific heat of Copper was calculated to be 0.262 J/g℃, even though the actual specific heat is 0.387 J/g℃. The percent error of that calculation is 32.299%. A considerable reason for this error is inaccurately reading the thermometer to the tenth degree digit…

Differences in thermoregulation patterns observed in the Monarch Butterfly, Danaus plexippus Many Lepidoptera species thermo-regulate using several patterns, physical and behavioral. These patterns are usually observed as movements from the shade and cooler areas to a place exposed to the sun as well as utilizing mechanical flight to generate heat. However, some species have intermediate behavioral patterns, often a mixture of basking and heat production, also known as endothermy (Kingsolver…

is the reaction between lithium hydroxide and water vapour to form lithium hydroxide monohydrate. LiOH(s) + H2O(g) LiOH•H2¬O(s) This reaction is followed by the endothermic formation of lithium carbonate. An endothermic reaction is the exact opposite of an exothermic reaction in which in an endothermic reaction, is a reaction that absorb energy from its surroundings in the form of heat. In this reaction lithium hydroxide monohydrate reacts with carbon dioxide to produce…

is added to the system, the chemical system will react by shifting the reaction to the side that will consume the heat. In this case, an increase in the temperature (heat) added to the left side which caused the reaction to shift to the right (endothermic). By producing more products, the heat added on the reactant is consumed. 2) The concentration of the products and the reactants suddenly spike. After this sudden increase, The concentration of the…

water using the formula ∆H=mC∆T. Calorimetry experiment or method is the process of measuring the amount of heat released or absorbed throughout a chemical reaction. By knowing the change in heat, it can be determined if a reaction is exothermic or endothermic. Some substances dissolve in some solutions and produce energy in the form of heat. These dissolution reactions are known as exothermic reactions. Example on the exothermic reactions is the reaction between sulphuric acid and water. When…

significantly the same as heat liberated during solidification. The small endothermic peak observed at 252.5 0C in the heating curve is attributed to the formation of silicon carbide (SiC). And also graphite…

feathers, which would have aided in insulating an internally maintained body temperature and hindered ectothermy. Finally, dinosaurs (in many cases) possess anatomies formidable for rapid movement. Rapid movement is most reliably facilitated in endothermic…

The great and evil Winter is going to take of the magical education government at OSU. He’s a rather hard target to defeat, since he’s a shapeshifter, and so far he’s succeeding at his goal. Anyways, two dragons, Moon and Sephira, are sitting in the middle of their very last class only half watching the presentation going on. And the presentation is Moon’s illusion, so technically, Moon is watching only half-watching herself try to earn a degree after 8 years of school for a chemistry PhD. The…

and even laptops and electronics have air conditioning which has allowed for appealing aspects of commercial use and consumer consumption, but what we don 't consider is how it uses heat, and the absence of heat to facilitate the exothermic and endothermic reactions to do work. Air conditioning controls humidity, ventilation and temperature, creating a fresh ambiance in warmer weather. It requires scientific topics which…
