Basically it just has to do with how the electrons orbiting the atoms in the molecules prefer to behave. Add: Reactions generally happen in order to cause the electrons to reach a lower, more stable energy state.
Cooking is a chemical process.
a chemical reaction makes something happen, like rust or water
the chemical shall be changed
In the cytoplasm, because that is where the chemical reactions happen.
No
No, but production of new molecules does happen.
Equillibrium
yes
well I'm not really sure but i think it needs time to mix in with each other and then it will cause a chemical reaction.
The chemical properties cannot be changed; only after a chemical reaction the products have new chemical properties.
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
When an acid and metal come in contact, a chemical reaction occurs where the metal will dissolve and release hydrogen gas. This reaction is known as a single displacement reaction, where the metal displaces hydrogen from the acid.
