What is a non-example of an exothermic reaction?
Any endothermic reaction, for instance photosynthesis.
Difference between endothermic and exothermic?
Endo draws heat from around it. Exo gives off heat. Example: Ice melting is a endothermic reaction. A match lighting is an exothermic reaction.An exothermic reaction releases heat to it's surroundings. The change in energy is negative. An example is combustion of natural gas.An endothermic reaction absorbs heat, so the temperature of the surroundings drops. The energy is positive. An example is melting ice cubes.
Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
Is a thermos endothermic or exothermic?
Endothermic: absorbs energy from surroundings in the form of heat. ie. outside temperature loses heat. Exothermic: releases energy into surroundings in the form of heat ie. outside temperature gains heat. Seeing as a thermos is supposed to MAINTAIN the temperature of its contents, it is neither.
Does endothermic or exothermic get colder?
Yeah, endothermic means that the heat is basically sucked out of it... or released while in an exothermic reaction, the heat is gathered or taken in. Take for example hot gas in a glass container: if it is cooled down of placed into a tub of ice, the gas will condense and the gas forms into droplets of liquid on the sides of the container and then drops to the bottom once there's enough of it.

Is the making of ice cubes an exothermic reaction?
exothermic. the energy flows out. exothermic. the energy flows out.
Is cold pack exothermic or endothermic?
Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.
Is melting scoop of ice cream an example of an exothermic process?
No, melting an ice cream scoop is an endothermic process because energy is absorbed to break the intermolecular bonds and change the solid ice cream into its liquid form.

Is the reaction of calcium chloride to ice a endothermic or exothermic reaction?
when CaCl2 is added to ice it becomes ionized slowly the ions become surrounded by water molecules the secondary types of bonding is responsible to evolve the heat so it is an exothermic reaction.
Is melting ice endothermic or exothermic change?
Ice cream melting (or pretty much anything melting) is an endothermic process in that it requires the absorption of heat energy in order to occur. An example of an exothermic process is the burning of paper which gives off heat energy.

Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
Is ice endothermic or exothermic?
Definitions Exothermic - accompanied by, or requiring, the release of heat. Endothermic - accompanied by, or requiring, the absorption of heat. Now, does the melting ice get warmer or colder? If it gets colder, then it is exothermic. If it gets warmer, then it is endothermic. Consider how we make ice - we put water into a cold place so that it gets colder with time.
Which reaction is an endothermic reaction?
Melting ice
Is the formation of ammonium nitrate crystals from an aqueous state endothermic or exothermic?
Endothermic. That is why it is used in ice packs.
Is dry ice exothermic?
Dry ice sublimation (changing from solid to gas) is an endothermic process because it requires heat energy to break the intermolecular forces holding the solid together. However, when dry ice sublimates in an enclosed space, it can release cold temperatures and feel cold to the touch, but this is due to the removal of heat energy from the surrounding environment, not due to an exothermic reaction.
