Why does an endothermic reaction feel cold if energy is being absorbed?

Because the energy(heat) is being pulled out of your hand. Heat transfer from the hottest substance to the coldest

What kind of reaction energy that requires energy in the form of heat?
Like baking a cake once you heat it, it becomes a new substance. With a chemical change you can never go back to what you had before. Also like a car rusting, a match being lite, and burning wood ( the new substance for wood is ash)
Energy stored formula?
e=mc2 Well - that IS one formula for energy. Another would be e = W = F∙d where e is energy W is work F is force d is distance Generally in thermodynamics we concern ourselves with changes in energy with work being done on or by a system and heat being added to or removed from it.
What occurs when energy is being given off or absorbed?
Heat is dissipated.
If the energy from the light is captured and stored by the surface without being reflected or transmitted then it has been?
Absorbed
If the energy from the light is captured and stored by the surface without being reflected or transmitted then it has been .?
Absorbed
How is energy conserved in an endothermic reaction?
Energy is conserved in an endothermic reaction because the heat absorbed becomes potential energy. This potential energy isn't lost energy, it's simply stored, instead of being used.
What is an endothermic reaction?
An endothermic reaction is one that absorbs heat from the surroundings.
What happens to energy in an endothermic reaction?
An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.
When enthalpy in a system increases what is the reaction considered to be?
When enthalpy in a system increases, the reaction is considered to be endothermic. This means that heat is being absorbed from the surroundings, resulting in an increase in the energy of the system.
What types of energy are released in exothermic reactions?
Exo -> Greek "Outside" Therm -> thérmē -> Greek "Heat" So an exothermic reaction releases heat energy. Related to that type of reaction is the endothermic reaction in which heat is absorbed into the reaction rather than being released by it.
What kind of a chemical reaction happens when hydrogen peroxide can break apart to form water and oxygen gas?
That would be a decomposition reaction. The equation for it would be: 2H2O --> 2H2 + O2 The process called electrolysis will do this.
Is magnesium ribbon burns an endothermic reaction or an exothermic reaction?
The reaction is highly exothermic as heat energy is released from the system to the surroundings whereas in endothermic the heat is absorbed from the surroundings into the system and you can also observe or see the smoke coming out of the apparatus in which the reaction is occurring or taking place.Heat energy is being released in the form of smoke.Therefore the reaction is exothermic.
Is a firecracker exploding an example of an endothermic reaction or an exothermic reaction?
Exothermic Reaction because the fizzing is CO2 being released as heat (energy).
What is a sentence for the term endothermic reaction?
When you heat calcium carbonate, to make it under go thermal decomposition, this is an endothermic reaction, because you are driving heat into the calcium carbonate.
When iron rusts is it an endothermic or exothermic reaction?
It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen
Is baking bread a endothermic and exothermic?
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
Is vaporization is a exothermic or endothermic?
Yes, vaporization is an endothermic reaction while freezing is an exothermic reaction. Think of a pot of water set of the stove. What are you doing to it? You're putting in heat in order to break the hydrogen bonds. The heat/energy is being expendedor absorbed to make the water boil. In the case of freezing (say water), the hydrogen bonds are realigning while producing heat.
