An endothermic reaction is one which requires the continuous input of energy. Although some reactions require energy to start them off, e.g. combustion of wood, they will then continue to react and will emit energy, mainly in the form of heat, in an exothermic reaction.
Baking a cake requires a continuous source of energy (i.e. the heat from an oven). If you turn the oven off, the cake will not continue cooking by itself. It is therefore endothermic.

Why is brownies a chemical change?
Because it is a mixture until it is baked and went through a chemical change and it is an endothermic reaction.
What is a chemical reaction that absorbs heat?
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
Is baking soda and citric acid a endothermic or exothermic reaction?
It is endothermic. The heat of the water in the calorimeter decreases (giving you a -deltaH), which means that the system absorbed heat, making the reaction endothermic.
A chemical reaction that absorbs free energy?
Can be called endothermic.
What chemicals are needed to create a constant endothermic reaction when heat is applied?
I presume you want example of endothermic reaction. Example is Saponification process (making soap) Photo synthesis (making sugar from CO2 and water) Heat of solution of many salt is endothermic.
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
Chemical reaction in which heat is absorbed?
It is an endothermic reaction. An example is thermal decomposition.
How does baking brownies relate to technology and science?
Well, One could take into consideration the ingredients for making the brownies, endothermic and exothermic properties in the baking, the technology in the oven and in the tools used to mix the ingredients.
Is water gas reaction endothermic?
yes it is a endothermic reaction
What is the difference between endothermicand and exothermic reaction?
An endothermic reaction absorbs energy, making its environment cooler. Ab exothermic reaction releases energy, making its environment warmer.
What kind of reaction is photosynthesis?
Photosynthesis is a Endergonic/Endothermic reaction.
