Answer:
magnesium
Explanation:
because zinc does not react with water because it too forms a protective layer of insoluble.
Answer:
d. All of the above three answers are correct
Explanation:
Atoms are themselves built up from many smaller particles. According to Rutherford's nuclear theory (1906), the neutron and proton make up the nucleus of the atom. Atoms are electrically neutral because they contain the same number of electrons and protons. The size of atoms is about
meters. The fundamental particle of the atom is the electron.
Answer: The precipitate formed is 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:

The right answer for the question that is being asked and shown above is that: "b. positive or negative charge" An isotope undergoes radioactive decay by emitting radiation that has no mass. The other characteristic does the radiation have is that b. positive or negative charge
