The valence electrons (electrons present in the outer most shell) are involved in a chemical reaction.
The primary factor that determines which substance is most responsible for chemical reactions is the reactivity of the substances involved.
Proteins involved in chemical reactions (speeding them up) are called enzymes. Note: most enzymes are proteins, but not all.

No. Only the electrons in the outer most shell take part in chemical reactions.
Not all chemical reactions require water. While many reactions may occur in the presence of water, there are also reactions that take place in other solvents or under dry conditions. The presence of water can often act as a catalyst or a medium for facilitating certain reactions, but it is not a universal requirement for all chemical reactions.
Most of the chemical reactions involved in metabolism require enzymes as catalysts to speed up the reactions. These enzymes help to lower the activation energy needed for the reactions to occur. Additionally, these reactions often require specific substrates and cofactors to proceed efficiently within the cells.
An important factor in all chemical reactions is the type and arrangement of atoms involved. The way in which atoms interact with one another dictates the outcome of a chemical reaction.
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
It is because salt is most involved in chemical reactions so it chemically changes it with rust.
Most chemical reactions occur in water, which is an inorganic compound. Water's unique properties, such as its ability to dissolve many substances, make it an ideal medium for chemical reactions to take place.
These are decomposition reactions.
