If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Is freezing an example of endothermic or exothermic change?
Freezing is an exothermic process because heat is released when a substance changes from a liquid to a solid, lowering the temperature of the surroundings.
Is spontaneous reaction exo or endo?
Reactions are described by this equation: GD = HD - TDS where D = delta for change in values. GD < 0 spontaneous HD < 0 exothermic ; HD > 0 endothermic The first equation is Gibbs free energy. When G is negative, the reaction is spontaneous. In contrast, a positive number G is non spontaneous. The interesting thing is that spontaneous reactions can be EITHER exothermic and endothermic. Lets look at this: lets assume HD has a value of 100. This means TDS would have to be bigger than 100 in order to make GD a negative number. An endothermic reaction which has a positive H can still be exothermic. Here's another way to pose your question: Is an exothermic reaction spontaneous? Always. Is an endothermic reaction spontaneous? This can be either.
What is the difference between an exothermic and an endothermic chemical reaction?
In an exothermic reaction, energy is released in the form of heat, making the surroundings warmer. In contrast, an endothermic reaction requires energy input from the surroundings to proceed, making the surroundings cooler as it absorbs heat.
What is a endopthermic reaction?
An endothermic reaction is a reaction where heat flows from the surroundings in to the system. Holding an cold pack to your skin is an endothermic reaction; heat flows from your skin (surroundings) into to the cold pack (system).
Is carbon dioxide formation endothermic and exothermic?
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
Is flammability endothermic or exothermic?
exo
Are all thermal decomposition reactions endothermic in nature?
Yes, but rather: 'most of all' combination reactions are exothermic. This is mostly true for spontaneous, common reactions.Examples of the contrary endothermic reactions, though rare, are:The formation reaction (= combination 'pur sang') of ethene, propene, acetylene, and even benzene is endothermic, when combined out of elements (that's why they are called endothermic compounds). Further a lot of metal hydride's, chlorous oxide: ClO2 are endothermic.The most Exceptional Endothermic Compound is:Dicyanoacetylene, IUPAC-name: but-2-ynedinitrile, C4N2 (or more structural: NC-CC-CN)Standard heat of formation Ho298 ( 4C + N2 --> ) is 500.4 kJ/molBecause of its high endothermic heat of formation, it can explode to carbon powder and nitrogen gas (reversed formation reaction, exo. 500.4 kJ/mol).It burns in oxygen with a bright blue-white flame at a temperature of 5260 K, which is probably the hottest flame of any chemical.
Is heat liberated in endothermic reactions?
No. Heat is given out (liberated) in exothermic reactions not endothermic. exo = out, therm = heat. Endothermic reactions take in heat energy from the surrounding wshich cause the surrounding temperature to decrease. endo = in.
Is solid to gas endo or exo?
Heat is required to solid for melting and to liquid for evaporation so these are endothermic processes.
When an electric eel shocks its prey is that endothermic or exothermic?
When it shocks its prey its exothermic. A simple way to remember this is Endo- = In and Exo- = Out.
What is an example of an endothermic change?
An example of an endothermic change is when an ice cube melts or when water evaporates. Endothermic is the opposite from exothermic. Exothermic means to take away energy,so endothermic means to add energy. If you take a test and this is on it remember the water cycle.Also remember that exo means to take OUT so endo means to ADD.
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Is freezing an example of endothermic or exothermic change?
Freezing is an exothermic process because heat is released when a substance changes from a liquid to a solid, lowering the temperature of the surroundings.
Are pygmy marmosets endothermic or ectothermic?
Mammals are endothermic, reptiles are exothermic. Endothermic animals can regulate their body temperature. Cold blooded or exothermic animals can not regulate their body temperature. Exothermic animals have to get their body heat from an outside source..hence the EXO....thermic. Endothermic is from the inside..hence the ENDO....thermic.
Will the temperature in a reaction always go up?
Exo- means out Endo- means in. In an Exothermic reaction thermal energy is released (goes out) and in an Endothermic reaction Thermal energy is taken up, transferring into chemical energy (goes in). So, to answer your question, no, the temperature does not go up in both an exothermic and an endothermic reaction.
Is freezing Endo or Exo?
Endothermic reactions absorb heat from their surroundings and feel cold, whereas exothermic reactions release heat into their surroundings and can feel warm. The sensation of freezing is typically associated with endothermic processes because they absorb heat during the reaction.
