The moon is made up mostly of Silicates, hope this answer helps.
That seems like a statement more than a question. Where's the question?
Answer:
5
Explanation:
The d subshell has 5 orbitals, each capable of holding a maximum of two electrons. Hund's rule tells us that every orbital in a sub-level must first be singly occupied by electrons before any orbital is doubly occupied. Therefore five electrons will fill the five orbitals within the d subshell.
We calculate current from the formula:
, where q is a electric charge transferred over time t
Time should be converted to seconds:
1h 15 min= 75min= 4500s
I=
Result is in unit-Ampere
In order to understand the results of another scientist's work, any scientist
who reads the report MUST understand the measurement system in which
the result is described. Otherwise the result is meaningless to him.
