The compound formed is calcium nitrate
Answer:
Diamond
Explanation:
As light moves from a less dense medium to a denser medium it slows down.
This is because the wave length of the light reduces. The denser the medium the less the wavelength. Diamond is the most dense solid among the provided choices thus light travelling through it has the least wavelength.

Answer:
Hydrothermal solutions
Explanation:
Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.
Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.
Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.
