During the chemical reaction, the iron atom lost two electrons, resulting in the formation of the Fe²⁺ ion. This loss of electrons occurs when iron reacts with other elements or compounds, leading to its oxidation. As a result, the iron atom transitions from a neutral state to a positively charged ion, which can participate in further chemical interactions.
If Fe becomes Fe^2+ it has lost 2 electrons, and so the Fe has been OXIDIZED.
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence
bcoz once paper is burned it cannot be turned back to its original form
Hormones are chemical messengers in the body that trigger physical changes during puberty. They are responsible for the development of secondary sexual characteristics such as breast development and voice changes. Hormones like testosterone and estrogen play a key role in the growth and maturation of reproductive organs.
Well, during the beginning, it started out fairly cool, then it became quite warm! It then went from hot to cold when the ice age kicked in!

When the egg is in its liquid form and then heated, a chemical reaction between the protein and amino acids cause it to harden therefore making your "Became chemical change"

It just happend
It became bigger I guess

It wasn't a chemical reaction; it was a physical reaction. The O rings (a type of gasket sealing the sections of the booster rockets) became too brittle due to cold weather. They failed and allowed the flames from the booster to melt and then ignite the external fuel tank. It was oxygen and liquid hydrogen
