Answer:
Explanation:
Mars is the fourth planet from the sun. Mars is more than 142 million miles from the Sun. A day on Mars is 24.6 hours. A year on Mars is 687 Earth days.
well its evaporation cuz it the suns heat heated the ice to the point where it turned to a gas, it could be conduction cuz the heat of the sunshine conducted the ice and turned it to a gas but that would be evaporation too so its not onduction, its not a chemical change cuz theres no new molecule the substance is itself, and its not a sudden change obviously
so the answer is A. evaporation~~~
Answer:
The fraction of the available octahedral positions are filled with 
ions is 
Explanation:
If there are n numbers of spheres in HCP in packing:
Number of octahedral void = n
Number of tetrahedral void = 2n
Total number of voids = n + 2n = 3n
The 
crystal structure consists of an HCP arrangement of 
ions.
Number of spheres in HCP = 6
Number of = 6
Number of octahedral voids = 6
Number of tetrahedral void = 12
Number of aluminum ions when there are 6 ion =
Number of voids in which 
ions are present = 4
The fraction of the available octahedral positions are filled with ions =
