Answer: No
Explanation: Some scientists have declared that mineral deposits containing important non renewable resources such as copper and zinc will be exhausted in a few decades if consumption does not decrease.
They are very stable. they have a "full table" so to speak. they have no valance electrons. they do not give electrons and they do not take them either. there are very few if an elements that can be paired with noble gasses
The number of electrons in a completely filled second shell of an atom is 8.
Hope this helped.
We are given with the mass of Arsine (
The mass of arsine is 15g
there is a relation between moles, mass and molar mass of any compound which is
The molar mass of Arsine = atomic mass of As + 3X atomic mass of H
the molar mass of Arsine = 74.92 + 3X 1 = 77.92 g/mol
Let us calculate the moles as
