Is it possible for a chemical to behave as an acid in one instance and as a base in another instance?
Yes, but not at the same time. Such substances are called amphoteric. Their acidic or basic character depends on the substance they are reacting with.
A good example of an amphoteric substance is water.
When water reacts with a substance more basic than itself (like ammonia), it acts as an acid.
H-OH + NH3 --> NH4+ + OH-
When water reacts with a substance more acidic than itself (like hydrochloric acid), it acts as a base.
HCl + H2O --> H3O+ + Cl-

What information does the activity series of a metal give?
It predicts of one metal will replace another metal in a compound.
What elements behave like carbon?
Silicon, germanium, and tin can behave similarly to carbon due to their ability to form covalent bonds and exhibit similar chemical properties. These elements are also capable of forming a diverse range of compounds, much like carbon.
Does bromine behave the most like krypton in chemical reactions?
I do not think that Bromine behaves like Krypton in chemical reactions. Krypton is very unreactive due to the fact that it has a full stable set of valence electrons, and Bromine is extremly reactive and has high electronegativity because is does not have a full stable set of valence electrons. Although, I do suppose that if a Bromine atom were to become a negative ion (Br+1) by gaining another electron, it would act as if it were a Krypton atom.
Why do the two isotopes of chlorine have the same chemical properties?
Oh, dude, it's like this - isotopes of an element have the same number of protons and electrons, so they behave chemically the same way. The number of neutrons might be different, but that's like saying you have different hair colors - doesn't change who you are on the inside, right? So yeah, chlorine isotopes are basically twins in the chemistry world.
Are all atoms of the same element chemically alike?
Not 100%; Istopes of an element do have identical electronic structures but there are slight differences in mass: 'Molecules with different isotopes of a particular element have different bonding characteristics: the bonds between the atoms are just a bit different because the atoms have different masses. As a result, the molecules with different isotopes behave a little bit different during chemical reactions.' See related link
When is a chemical most likely to behave as an acid?
Acid is a major chemical that behaves both as an acid and as a base. Another chemical would be KOH.
Can a chemical behave as an acid and a base?
yes.
