A change of state where energy is given off?
This process is called exothermic reaction, where energy is released in the form of heat. It typically involves a change from a higher energy state to a lower energy state, resulting in the release of energy to the surroundings. An example would be the solidification of molten lava into solid rock, releasing heat energy in the process.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
The activation energy of an endothermic reaction is at least as large as its enthalpy change because the reactants require a minimum amount of energy to reach the transition state where bond-breaking and bond-forming occur. The enthalpy change represents the overall energy difference between reactants and products but does not account for the energy needed to overcome the energy barrier (activation energy) for the reaction to proceed.
can you relate endothermic and exothermic reactions to specifically the making and breaking of bonds?
An exothermic reaction releases energy when bonds are formed, leading to a lower energy state compared to the reactants. In contrast, an endothermic reaction requires energy input to break existing bonds and form new ones, resulting in a higher energy state than the initial reactants.
Is the melting of candle wax and exothermic or endothermic change?
The answer is endothermic. The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat). If the reactants give off heat of their own (self sustaining), then it is an exothermic reaction. There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.
What is a change of state that reacts when energy is endothermic?
An endothermic reaction is one that takes heat from its surroundings to increase the delta H or energy level. it causes the surroundings to lower in temperature as it absorbs heat from the surroundings e.g cooling packs. the change in state depends on what reaction is taking place, e.g melting ice cubes - solid to liquid boiling water - liquid to gas (they both absorb heat to occur)
A change of state reaction that absorbs energy is endothermic?
yes it is endothermic
A change of state reaction of what Energy is endothermic?
absorbed
Which change of phase is endothermic?
is Absorbs If you are asking if a change of state is why a reaction may be endothermic, is not always true. It simply depends on what the change of state is to and what it is from, ex: a change from liquid to solid is usually exothermic because it losses energy as the particles slow down and draw near to eachother... and the opposite occurs from solid to liquid (or liquid to gas).
The change in which ice absorbs energy and melts is?
An endothermic change; or a change of state. Endothermic because it absorbs energy. Change of state because ti changes from a solid to a liquid.
A change in matter in which energy is taken in is an endothermic change?
Endothermic changes are processes where energy is absorbed by the system from its surroundings. This results in a decrease in temperature in the surroundings during the process. Examples include melting ice and evaporating water.

Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
can you relate endothermic and exothermic reactions to specifically the making and breaking of bonds?
An exothermic reaction releases energy when bonds are formed, leading to a lower energy state compared to the reactants. In contrast, an endothermic reaction requires energy input to break existing bonds and form new ones, resulting in a higher energy state than the initial reactants.
Is water freezing an example of an endothermic reaction?
No, water freezing is not an endothermic reaction; it is an exothermic process. During freezing, water releases heat to its surroundings as it transitions from a liquid to a solid state. This release of energy is what causes the temperature of the surroundings to decrease. In contrast, an endothermic reaction absorbs heat from the environment.
Is the melting of candle wax and exothermic or endothermic change?
The answer is endothermic. The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat).

There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.
Why is evaporization an endothermic?
Evaporization is an endothermic reaction which causes a substance to be released into the air. This is typically associated with the change from one state of matter to another like liquid to gas.
