What evidence is there to show that a chemical reaction has taken place when an egg is cooked?
The change in color indicates that a chemical reaction has taken place.
How do you know a reaction occurred?
A reaction has occurred when there are observable changes, such as a color change, the formation of a precipitate, the evolution of gas (bubbles), or a temperature change (exothermic or endothermic). Additionally, if the properties of the original substances change and new substances with different properties are produced, it indicates that a chemical reaction has taken place. Observing these signs can confirm the occurrence of a reaction.
What is a chemical reaction in which more energy is taken in than given off?
An endothermic reaction is a chemical reaction in which more energy is taken in than given off. This means that energy is absorbed from the surroundings during the reaction, causing a decrease in temperature. An example of an endothermic reaction is the reaction between baking soda and vinegar.
What is the difference between endothemic and exothemic?
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
What takes place in the stoma of the chloroplasts?
Dark reaction is taken place. It is the light independent reaction

What is different between exothermic and endothermic reactions?
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
What is the name given to reactions which take in heat?
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.

The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Are hand warmers exothermic or endothermic?
Exothermic Because exothermic means heat is released and endothermic means heat is taken in.

Dark reaction is taken place. It is the light independent reaction
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
Does energy decrease or increase during a chemical reaction?
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
