higher potential energy and delta h increases
when the reaction is complete more energy was used to form bonds than to break them.
Endothermic, if the energy is in the form of heat.
For example the chemical reactivity.
bromine combines with aluminum to produce AlBr3.
An endothermic reaction is one that uses chemical energy.
Can be called endothermic.
Endothermic, if the energy is in the form of heat.
Endothermic describes a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature. (adjective)
You did not write any of those chemical names correctly (methane is CH4, not ch4) and all you did was list 4 incorrectly written chemicals, you did not give a chemical equation. Only a chemical reaction can be described as endothermic or exothermic; chemicals by themselves do not have those properties.
For example the chemical reactivity.
bromine combines with aluminum to produce AlBr3.
An endothermic reaction contains more chemical energy.
An endothermic reaction is one that uses chemical energy.
Can be called endothermic.
It is an endothermic reaction. An example is thermal decomposition.
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.
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.
