Both California and Peru have or have had significant gold deposits because of their proximity to where two tectonic plate boundaries meet. Off the California coast there is the Pacific Plate and the North American Plate which meet at the San Andreas Fault but there also is the Farallon Plate which apparently has subducted somewhat below the North American Plate. Off Peru, the Nazca Plate is subducting under the South American Plate and which has caused the Andean orogeny.

Answer:
The specie which is oxidized is:- 
The specie which is reduced is:- 
Explanation:
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
For the given chemical reaction:
The half cell reactions for the above reaction follows:
Oxidation half reaction: 
Reduction half reaction: 
Thus, the specie which is oxidized is:-
The specie which is reduced is:-
Answer:

And that is Q
Explanation:
Answer:
Bromine mollecules are held together by van der waals forces while a water molecule constitutes both van der waals forces and hydrogen bomnding
Explanation:
This makes the water molecule recquire more heat energy to break the bond thus a higher boiling point while bromine structure requires just litttle heat energy
