Answer:
Which best describes the geologic time scale? It explains why events happen throughout Earth’s history. It presents the correct sequence of events in Earth’s history. It is used to determine the absolute dates in years for different periods.
Answer:
Explanation:
From the question we are told that:
Edge length of the unit cell 
a)
Generally the equation for The relationship between edge length and radius is mathematically given by
Therefore
b)
From the question we are told that:
Density 
Edge length of 
Therefore Volume is given as
Generally the equation for Mass is mathematically given by
Therefore Molarity is given as
Finally The atoms in a unit cell is
Many transition metal ions(e.g. in soluble salt solutions) give colored hydroxide precipitates when mixed with aqueous sodium hydroxide solution. However zinc ions give a white hydroxide precipitate. These reactions can be used to help identify transition metal ions in solution.

Answer:
8 moles of C
Explanation:
From the question given above, the following equation was obtained:
3A + 2B —> 6C
From the equation above,
3 moles of A reacted to produce 6 moles of C.
Thus, the number of mole of C produced by reacting 4 moles of A can be obtained as follow:
From the equation above,
3 moles of A reacted to produce 6 moles of C.
Therefore, 4 moles of C will react to produce = (4 × 6)/3 = 8 moles of C
Thus, 8 moles of C can be obtained from the reaction of 4 moles of A with excess B
