What chemical reaction describes where energy is absorbed?
Endothermic, if the energy is in the form of heat.
An endothermic reaction is one that uses which form of energy?
An endothermic reaction is one that uses chemical energy.
A chemical reaction that absorbs free energy?
Can be called endothermic.
Chemical reaction in which heat is absorbed?
It is an endothermic reaction. An example is thermal decomposition.
Are melting and freezing physical changes are endothermic?
Freezing is an endothermic change. Freezing, for example a puddle of ice turn into an ice cube, the water is still the same thing but its just in a different form. The water is going into a different form, which is called endothermic. Hope this helped :)!
What chemical reaction describes where energy is absorbed?
Endothermic, if the energy is in the form of heat.
Which contains more chemical energy endothermic or exothermic?
An endothermic reaction contains more chemical energy.
An endothermic reaction is one that uses which form of energy?
An endothermic reaction is one that uses chemical energy.
A chemical reaction that absorbs free energy?
Can be called endothermic.
Chemical reaction in which heat is absorbed?
It is an endothermic reaction. An example is thermal decomposition.
What is a chemical reaction that absorbs heat?
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
What type of chemical absorbs energy?
The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
What is a chemical reaction is endothermic?
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
Is evaporating sea water to leave salt physical or chemical?
chemical
Are melting and freezing physical changes are endothermic?
Freezing is an endothermic change. Freezing, for example a puddle of ice turn into an ice cube, the water is still the same thing but its just in a different form. The water is going into a different form, which is called endothermic. Hope this helped :)!
Water evaporating is it chemical or physical?
physical
