Exothermic reactions give out heat.
some examples of exothermic reactions are :
1)burning fuel in a fire
2)the addition of acid to water
3)the thermite reaction(this one is quite a sight)
4)the haber process of producing ammonia
Endothermic reactions take in heat from their environment.
some examples of endothermic reactions are:
1)an ice cube melting
2)depressurising a can(responsible in part why deodorant feels cold)
3)dissolving ammonium nitrate in water
4)decomposition of Mercury (II) oxide(this requires a lot of heat)
What else can I help you with?
What is a sentence using endothermic and exothermic?
Plants are endothermic because they use photosynthesis as their means of obtaining energy and endothermic means energy obtaining. A candle flame would be considered exothermic because it releases heat.
What chemical reactions are exothermic?
Any chemical reaction that produces energy is exothermic. A erection that requires energy is endothermic. For instance, NaCl + H20 -> HCl + NaOH is endothermic. Run the equation the opposite direction, HCl _+ NaOH -> NaCl + H20 and it's an exothermic reaction.
Is stone exothermic or endothermic?
It depends on the situation. Suppose the stone is placed in a cup of hot water. It is now endothermic because it absorbs some of the heat. But if it is placed in a cup of frigid water, it is exothermic because it will release some of its heat as it drops in temperature. --------------------------------------------------------------- Endothermic or exothermic are terms used for processes, phenomenons, reactions not for materials.
Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
The reaction between potassium permanganate and glycerin is exothermic, which means it releases heat as it proceeds. This reaction is highly exothermic and can lead to spontaneous combustion in some cases.
Is polymerization endothermic or exothermic?
Exothermic, because the reaction enthalpy must be negative. With polymerization, the entropy decreases. The Gibbs energy has to be negative. Thus negative reaction enthalpy. Gibbs energy = reaction enthalpy - temperature*entropy
Is curium endothermic or exothermic?
The terms exothermic and endothermic are applicable to chemical or physical reactions, not to materials. But because curium is an radioactive element, of course some thermal radiation is emitted.
What are some examples of endothermic birds?
All of them are endothermic.
What is a sentence using endothermic and exothermic?
Plants are endothermic because they use photosynthesis as their means of obtaining energy and endothermic means energy obtaining. A candle flame would be considered exothermic because it releases heat.
What are some examples of endothermic reactions that are endothermic as well?
All ENDOthermic reactions are of course ENDOthermic by themselves, aren't they?
Do chemical reaction absorb energy spontaneously or do they release them?
Some chemical reactions are exothermic, some are endothermic.
What chemical reactions are exothermic?
Any chemical reaction that produces energy is exothermic. A erection that requires energy is endothermic. For instance, NaCl + H20 -> HCl + NaOH is endothermic. Run the equation the opposite direction, HCl _+ NaOH -> NaCl + H20 and it's an exothermic reaction.
What Are some similities between photosynthesis and endothermic reaction?
It is a exothermic reaction. So there is nothing similar.
Is stone exothermic or endothermic?

Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
The reaction between potassium permanganate and glycerin is exothermic, which means it releases heat as it proceeds. This reaction is highly exothermic and can lead to spontaneous combustion in some cases.
Examples of endothermic and exothermic reactions?
Exothermic reactions give out energy overall. Here are some exothermic reactions:- Combustion of fuels such as hydrogen & methane- Neutralisation of an acid by an alkali- Reaction between sulphur & ironEndothermic reactions take in energy overall. Here are some endothermic reactions:- Reactions involved in cooking- The thermal decomposition of calcium carbonate- Photosynthesis in which plants use sunlight, carbon dioxide & water to make their own food
Is polymerization endothermic or exothermic?
Exothermic, because the reaction enthalpy must be negative. With polymerization, the entropy decreases. The Gibbs energy has to be negative. Thus negative reaction enthalpy. Gibbs energy = reaction enthalpy - temperature*entropy
Is the reaction of magnesium sulphate and water exothermic or endothermic?
The stuff is actually used in some hotpacks. It's exothermic.
