Exothermic the root of the word is therm which relates to heat and these word indeed means a reaction that releases heat. Releases, it releases heat. And one way to think about it if you're thinking about constant pressures or change in enthalpy it can be viewed as your, how much heat you absorb or release.

Transcribed image text: Which one of the following is an endothermic process? A) ice melting B) water freezing C) boiling soup D) Hydrochloric acid and barium hydroxide are mixed at 25 degree C: the temperature increases. Effect of temperature on solubility of a salt lab answer key. Question: Which of the following processes is/are endothermic? 1. the combustion of hydrogen 2. the condensation of water 3. the evaporation of isopropyl alcohol This problem has been solved! See the answer Show transcribed image text Expert Answer 100% (5 ratings) Answer - 3) The evaporation of isopropyl … View the full answerDetailed Solution. Option 4 is correct, i.e (i) and (iii). An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur. Photosynthesis: Plants absorb heat energy from sunlight to convert carbon dioxide and water into glucose and oxygen. State which of the following processes is endothermic and which is exothermic. (i) The breaking of a chemical bond. (ii) The forming of a chemical bond. b. The table below shows the bond energy data for a series of covalent bonds.
  2. An endothermic reaction is one in which heat energy is needed (absorbed) during the reaction. In the thermochemical equation for the endothermic reaction, the heat energy is on the reactants side. The enthalpy of reactants is lower than the enthalpy of products. The enthalpy change of an endothermic reaction is positive.An endothermic reaction is one in which heat energy is needed (absorbed) during the reaction.

(i) Dilution of sulphuric acid (ii) Sublimation of dry ice (iii) Condensation of water vapours (iv) Evaporation of water (a) (i) and (iii)Reactions can either release or absorb energy in the form of heat; Endothermic reactions absorb heat while exothermic reactions release heat. The absorption and release of heat can be represented quantitatively by enthalpy (H), which equates to the heat content of a system. A positive +ΔH value results in a gain of heat in a system, which ... State which of the following processes is endothermic and which is exothermic. (i) The breaking of a chemical bond. (ii) The forming of a chemical bond. b. The table below shows the bond energy data for a series of covalent bonds.
  3. Nov 19, 2021 · Exothermic Reactions – The opposite of an endothermic reaction is an exothermic reaction. It releases energy to its surroundings in the form of light or heat. Neutralization, burning a chemical, fuel reactions, deposition of dry ice, respiration, sulfuric acid solution in water, and many more processes are examples. Commercial processes of direct dehydrogenation include thermal cracking of ethane and catalytic dehydrogenation of propane. However, dehydrogenation is a strong endothermic process with its conversion limited by thermodynamic equilibrium, which makes the reaction proceed at a high temperature with massive energy consumption.Allis chalmers 7050 specs

Which of the following reaction is endothermic? A. C + O → CO B. CaO + H O → Ca (OH) C. C + H O → CO + H D. HCl + NaOH → NaCl + H O Correct Answer: Option C ExplanationCrazyluck casinoIf the enthalpy change listed for the reaction is positive, then that reaction absorbs heat as it proceeds — the reaction is endothermic (endo-= in). In other words, exothermic reactions release heat as a product, and endothermic reactions consume heat as a reactant. The sign of the >
